What is the net amount of energy released when one mole of h2o(?) is produced?

[ad_1]

The net amount of energy produced can be obtained from a table of enthalpy change of formation, available online.

The enthalpy change of formation indicate how much energy the 1 mole of the product (H2O) has relative to the elemental reactants (H2 and O2).  In other words, the “lost” energy equals the heat/energy released. 

For water (H2O), this value is -285.8 if the final product is a liquid under standard conditions, and -241.82 if the product is in gas form which contains some energy that could be further released.  This means that if the final product (H2O) is in liquid form, energy released is 285.8 kJ/mol.

Since water is in liquid form under standard conditions, the first value (285.8 kJ/mol) is generally appropriate.

True or false? Health Insurance Portability and Accountability Act (HIPAA) regulations have made medical records release forms more complex by requiring more information and giving the patient more options to restrict the information released.

[ad_1]

1. The answer is “C”.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

2. The answer is “A”.

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in “consensus democracy” in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

A balloon is released from a tall building. the total mass of the balloon including the enclosed gas is 2.0 kg. its volume is 5.0 m3. the density of air is 1.3 kg/m3. will the balloon rise, fall, or remain stationary; and why?

[ad_1]

The gravitational force Fg between two objects is given by the equation:

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies. 

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface. 

m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h. 

So the time for the pencil and eraser to touch is T=1.3449 hours. 

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

Answer:

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

_____ is(are) released when blood glucose levels drop.

[ad_1]

The blood type is B+. The blood type depends on some protein substances called antigens present on the cell membrane of the red blood cells that help the cells to identify and communicate with each other. There are four types of blood types;
1- Blood type A which have antigens A on the red blood cells.
2- Blood type B which have antigens B on the red blood cells.
3- Blood type AB which has antigens A and B on the red blood cells.
4- Blood type O which have no antigens on the red blood cells.
There is a second type of antigens present on the red blood cells which is called rhesus. Rhesus may be present, so the individual will be positive (+) rhesus), or it may be absent, so the individual will be negative (-) rhesus.
To determine the blood type, we add anti-a and anti-b serums to two samples of the tested blood.
If the anti-a coagulates only, the person is blood type A.
If the anti-b coagulates only, the person is blood type B.
If the two samples coagulate, the person is blood type AB.
If the two samples don’t coagulate, the person is blood type O.
To another blood sample from the same blood, we add anti rhesus, if it coagulates, the person is )+), if not the person is (-).

A positive cahnge of enthalpy, ΔH rxn = + 55 kJ/mol, for the forward reaction means that the reaction is endothermic, i.e. the reactants absorb energy and the products are higher in energy.

Activation energy is the difference in the energy level of the reactants and the peak in the potential energy diagram (the energy of the transition state).

For an endothermic reaction, the products will be closer in energy to the transition state than what the reactans will be; so, the activation energy of the reversed reaction is lower than the activation energy of the forward reaction.

Activation energy of reverse and forward reactions is related by:

Activation energy of reverse rxn = Activation energy of forward rxn – ΔH rxn

=> Activiation energy of reverse rxn = 102 kJ/mol – 55 kJ/mol = 47 kJ/mol

Answer: 47 kJ/mol

H2O has a Hvap = 40.7 kJ/mol. What is the quantity of heat that is released when 27.9 g of H2O condenses?

[ad_1]

You have to assume that the hydrocarbon contains only C, H and, possibly, O.

Then, all the C in CO2 and the H in H2O come from the hydrocarbon.

a) Number of moles of C in 23.8 g of CO2.

molar mass of CO2 = 12.0 g + 2 * 16.0 g = 44.0 g / mol

number of moles of C = mass in grams / molar mass = 23.8 g / 44.0 g/mol = 0.5409 mol

b) number of moles of H in 8.11 g of H2O

number of moles = mass in grams / molar mass = 8.11 grams / 18.0 g/mol = 0.4506 mol

c) mass of O in the hydrocarbon, m of O:

m of O = 7.40 g – mass of C – mass of H

mass of C = number of moles * atomic mass = 0.5409 mol * 12 g/mol = 6.49 g

m of H = 0.4506 mol * 1 g /mol = 0.45 g

=> grams of O = 7.40 g – 6.49 g – 0.45 g = 0.46 g of O.

d) number of moles of O = mass / atomic mass

=> number of moles of O = 0.46 g / 16 g / mol = 0.02875 mol O.

e) Empirical formula

C: 0.5409 / 0.02875 = 18.8 ≈ 19

H: 0.4506 / 0.02875 = 15.7 ≈ 16

O: 0.02875 / 0.02875 = 1

=> Empirical formula = C19 H16 O

The intertidal zone is the area of the seafloor between high tide and low tide. It bridges the gap between land and water. Tide pools, estuaries, mangrove swamps and rocky coastal areas are all part of the intertidal zone.

Neritic zone

The water above the continental shelf is the neritic zone. Underwater forest of kelp and grassy meadows of sea grass are home to tiny fish, green turtles, sea cows, seahorses and tiny shrimp. Coral reefs have thousands of animals and plants that live in the waters of the neritic zone.

Open ocean zone

The open ocean zone lies beyond the continental slope and contains 65% of the water in the oceans. This zone is divided further into three subzones. The sunlit zone is where photosynthesis takes place. Plankton and jellyfish are drifters that inhabit this zone. Most animals living in the open ocean live in the sunlit zone.

Twilight zone

Below the sunlit zone is the twilight zone where some light penetrates the ocean to a depth of 3000 feet. Viper fish, firefly squid, and the chambered nautilus live in this zone. The midnight zone extends from a depth of 3000 feet to the seafloor. Animals found in this zone include the giant squid, deep sea hatchet fish

and bioluminescent jellyfish.

Benthic zone

The benthic zone includes the entire seafloor. About 200,000 species of plants and animals live here. They live on the continental shelf and continental slope. Hydrothermal vents discovered in 1977 are also teeming with life. These plants and animals doe not need sunlight to exist.

Lise Marie J. de Baissac came from a French family. She was born in Mauritius and had British nationality. She was the superstar of the Special Operations Team at the time of WW-II. She was a dignified agent who, multiple times, risked her life in order to work in national spy operations. After the war seized, she was received numbers of gallantry prizes.

However, the reason after every option for its acceptance or nonacceptance as the answer is mentioned beneath each point. Anyhow, the correct answer is darkened.

A. “When she … lived there.”

This line only defines a specific detail about how the special agent survived through a fake name as a spy. No theme is described through this sentence.

B. “Baissac’s goal … resistance groups.”

This statement the agent’s motive and the way she enacted the task provided. Still, the complete idea is not expressed within the line.  

C. “Baissac did … her tasks.”

The writer is praising the efforts of Baissac in this sentence. He again writes how much hard work the agent did in order to achieve the national goals.

D. “As a … German troops.”

This is the statement that definitely defines the central idea of the excerpt. When we break this line into sections, we can see that it illustrates that she performed multiple essential tasks when appointed in Normandy. The phrase “sometimes dangerous tasks” describes the critical nature of the job she handled in there. And, also the opposition (German troops) is clearly mentioned in this sentence which helps to convey the idea very clearly.
