Hydrogen gas (H2) occupies a volume of 100.0 mL at 27°C and 300 Torr. What pressure will it have if it's cooled to –73°C and the volume remains constant?

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.

All motion is caused by force? true or false
