When water freezes, its volume is increased by one-eleventh. In other words, the volume of ice equals the sum of the volume of the original amount of water and the product of one-eleventh and the volume of the water. If 979 cubic centimeters of water is to be frozen, what will be the volume of the ice that will be formed?

How many liters of hydrogen gas are collected over water at 20°C and 725 mmHg when 0.75 g lithium reacts with water? Aqueous lithium hydroxide also forms.
solid NaI is slowly added to a solution that is 0.010 M in Cu+ and 0.010 M in Ag+. which compound will begin to precipitate first?
whats the amount of heat required to raise the temperature of 165 g of water from 12.0 C to 88.0 C (sp. heat of H20(l)= 4.18 J/g)
H2S and H2O have similar structures and their cenertal atoms belong to the same group. Yet H2S is a gas at room temperature and H2O is a liquid. Use bonding principles to explain why this is.
How many grams of CO2 were used during the month? molar mass of CO2 is 44.00995 g/mol.
describe the reactant and products of the chemical reaction. Qas the reactant (potato chip) completely consumed? What evidence supports your answer?
Suppose the calorimeter for this experiment had been made of a heat-conducting material (such as metal) rather than plastic foam, so that the portion of heat energy lost to the calorimeter itself was larger and could not be ignored
A fluid has a density of 4.25 g/mL. If you need to acquire 5.0 g of the fluid, how much volume will you need to draw?
