A chemist wishes to perform the following reaction between nitrogen gas and hydrogen gas to produce ammonia: N2 + 3 H2 → 2 NH3
If 10.7 g of hydrogen gas is available, what is the maximum amount, in grams, of ammonia can be produced?

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.

Which change to the system wood cause the freely-moving piston to lower?
