Write the net ionic equations for the reactions.
an unknown gas has a density of 1.60 g/L at 1.00 atm and 30.5 degrees celsius what is the molar mass of the gas.
The initial volume of a sample of argon gas is 415 mL at 323°C. If the pressure is held constant and the volume is changed to 599 mL, what will be the new temperature (in °C)?
Nickel nitrate and potassium carbonate react to form nickel carbonate and potassium nitrate. How many milliliters of 0.55M Ni(NO3)¬2 are needed to react with 85 mL of 0.25M K2CO3? First, write a balanced equation.
The EPA limit for lead in the water supply is 15 parts per billion by mass. Calculate the number of lead ions present in 1.00kg of water that is at the EPA limit for lead.
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.
