What volume 12.6 M HCL must be added to enough water to prepare 5.00 litters of 3.00 M HCL?

[ad_1]

To solve this problem, we shall use the role;
M1V1 = M2V2
M1: is the molarity of the solution before dilution.
V1: is the volume of the solution that we need to dilute.
M2: is the molarity of the solution after dilution.
V2: is the volume of the solution after dilution.

By substitution;
12*V1 = 3*5
V1 = 1.25 litters.

Use the equation where p = pressure and V = volume. What happens to the pressure as the volume approaches 0? Explain your reasoning.

[ad_1]

Answer:-  The pressure ‘p’ will be infinity at volume ‘V’=0.

Explanation:-

The given equation :- p=frac{8.31}{V} where p is a rational function dependent on V.

A rational function is undefined for denominator = 0.

In the given function V is the denominator , if V=0 then the function will be undefined.

⇒ p will approach to zero at V=0.

For assistance see the attachment , the graph of the given function represented by vertical assymptote which approaches to 0 but never touches it..

The length of the base of a rectangular pyramid is tripled, the width of the base remains the same, and the height of the pyramid is divided by 7. What volume formula reflects these changes?

[ad_1]

Answer with Step-by-step explanation:

The volume of a rectangular pyramid is given by:

V=lbh/3

Where l is the length

b is the breath  

and h is the height.

Now, l’,b’ and h’ be new length,breath and height

Then, l’=3l

b’=b

and h’=h/7

New volume=V’=l’b’h’/3

                         = dfrac{3ltimes btimes dfrac{h}{7}}{3}

                         = dfrac{lbh}{7}

Hence, Volume formula which reflects these changes is:

dfrac{lbh}{7}

Calculate the ph of 0.375 l of a 0.18 m acetic acid-0.29 m sodium acetate buffer after the addition of 0.0090 mol of koh. assume that the volume remains constant.

[ad_1]

To calculate the pH of this solution, we use the
Henderson-Hasselbalch equation: 

pH = pKa + log ([A-]/[HA])

Where,

[A-] = Molarity of the conjugate base =
CH3COO- = 0.29 M
[HA] = Molarity of the weak acid  = CH3COOH = 0.18 M

pKa = dissociation constant of the weak acid =
4.75

When KOH is added to the buffer, the chemical
reaction is:

CH3COOH + KOH = CH3COO-K+ + H2O

Therefore when 0.0090 mol KOH is added, 0.0090
mol acid is neutralized, and 0.0090 mol CH3COO- is produced.

[CH3COO-] = [0.0090 mol + 0.375 L (0.29 mol/L) ]
/ 0.375 L = 0.314 M

[CH3COOH] = [-0.0090 mol + 0.375 L (0.18 mol/L) ]
/ 0.375 L = 0.156 M

Going back to Henderson-Hasselbalch
equation:

pH = 4.75 + log (0.314 / 0.156)

pH = 5.054

A sample of carbon dioxide gas, co2 (g), occupies a volume of 5.75 l at 0.890 atm. if the temperature and the number of moles remain constant, calculate the volume when the pressure a. increased to 1.25 atm b. decrease to 0.350 atm

[ad_1]

According to Boyle’s law;
P1V1 = P2V2
P1 is the pressure of the gas in the first case.
V1 is the volume of the gas in the first case.
P2 is the pressure of the gas in the second case.
V2 is the volume of the gas in the second case.

P1 = 0.890 atm, V1 = 5.75l

a. P2 = 1.25 atm, 
0.890*5.75 = 1.25*V2
V2 = 4.094 l

b. P2 = 0.350 atm,
0.890*5.75 = 0.350*V2
V2 = 14.621 l.

Our water footprint includes the volume of freshwater we use ________ . a. directly b. for irrigation c. indirectly d. both directly and indirectly e. in households

[ad_1]

Answered by answersmine AT 22/10/2019 – 05:01 AM

Water footprint is the measurement of the amount of fresh water utilized in the production or supply of the goods and services used by a particular person or group. The water footprint tells us how much water is used in a single process (for example: production of one T-Shirt, but it is also an indicator for the amount of water consumed by a particular country or nation.
So, our water footprint includes the volume of freshwater we use both directly and indirectly.
