Carbon dioxide can be formed from the reaction of carbon monoxide and oxygen. How many moles of carbon monoxide must be reacted in order to produce 147 kJ of energy?
2 CO + O2 -> 2 CO2 ΔH = -787 kJ

Layers of rock containing fossils, like the layers illustrated here, are most likely composed of rocks.

In a spacecraft, the following reaction occurs: co2(g) + 2lioh(s) -> lico3(s) + h2o(i) (i attached picture of equation) how many liters of carbon dioxide will 4 moles of lithium hydroxide (lioh) absorb? (one mole of any gads occupies 22.4 l under certain conditions of temperature and pressure. assume those conditions for this equation.) 45l 6.0l 3.0l 34l
