A helium balloon has a volume of 2.30 L at 23.5 oC and a pressure of 1.00 atm at sea level. The Balloon is released and floats upward. At a certain height the atmospheric pressure is 0.810 atm and the temperature is 12.0 oC. Calculate the volume of the balloon.

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.

How many liters of water vapor can be produced if 108 grams of methane gas (ch4) are combusted at 312 k and 0.98 atm? show all work. pls ! will mark as brainliest
