Giovanni created this chart to study for an exam. Compound I uses ———————————————————————————————————— Sodium Hydroxide (NaOH) Plastic, soap, and paper production ———————————————————————————————————— Iron oxide (FeO) Toothpastes and antacids ———————————————————————————————————— Calcium chloride (caCl2) Snow removal ———————————————————————————————————— Calcium carbonate (CaCO3) Dark pigment in makeup Which best describes how to correct the error in the chart? A) Remove “plastics” from the uses for sodium hydroxide. B) Swap the uses for iron oxide and calcium carbonate. C) Change the use for calcium chloride to “used in preservatives.” D) Add “de-ice roads” to uses for calcium carbonate.

Answer; B) Swap the uses for iron oxide and calcium carbonate. Explanation; Calcium carbonate is a compound that is naturally found in marble, chalk and limestone. It is used in pharmaceutical applications as a cost effective dietary calcium supplement, and also used in antacids. Calcium carbonate is also found in …

A certain skin lotion is a fine mixture of water and various oils. This lotion is cloudy and cannot be separated into oil and water by filtration. Moreover, its components do not separate when left standing. What type of mixture is it? solution suspension colloid compound NextReset

The answer is: colloid. In the presence of an emulsifying agent, a mixture of oil and water becomes a colloidal dispersion. Colloidal dispersion (colloid) is a system, in which discrete particles, droplets or bubbles of a dispersed phase (in this case oil), whose size at least in one dimension is …

Choose the ionic compound from the following choices A)Cesium BromideB)Nitrogen Tirfluoride C)Soduim Chloride D)Carbon Dioxide

The best way to figure out ionic compounds is to simply look at where each element is on the periodic table. Ionic compounds tend to be on opposite sides of the periodic table.This is because a compound is ionic if one element gives up electrons and one receives electrons. Because …

– How many moles of NaHCO3 can be produced from 125 mol of NaCl – How many moles Of H2O are produced when 6 mol of O2 is consumed in burning methyl alcohol, CH3OH, according to the following equation? – Solutions of iron(III) chloride, FeCl3, are used in photoengraving and to make ink. This compound can be made by the following reaction. a. How many moles of FeCl3 form from 31 mol of Cl2? b. How many moles of Fe are needed to combine with 5 mol of Cl2 by this reaction? c. If 0.62 mol of Fe is to be used by this reaction, how many moles of FeCl3 form? – Ammonia is produced synthetically by the reaction: a. Is this an exothermic or endothermic process? b. How many moles of NH3 are formed when 1 mol of N2 reacts with hydrogen? c. If 18 x 1023 molecules of H2 react with nitrogen, how many moles of NH3 are produced?

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 …
