The complete combustion of ethene gas, C2H4, and water vapor. If 35.0 grams of water were produced, (A) calculate the volume of carbon dioxide produced. (B) calculate the volume of ethene used. (C) calculate the volume of air required to supply the oxygen needed for the reaction

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.

The mass of a neutron is equal to the mass of a proton plus the mass of an electron. true or false false true

Avariable that is not being directly tested during an experiment should be
