2 H2 + CO → CH3OH Methanol (CH3OH) can be produced through the reaction of carbon
monoxide and hydrogen gas in the presence of a catalyst. If 75.0 g of
carbon monoxide react to produce 68.4 g CH3OH, what is the percent
yield of CH3OH? (molar mass of CH3OH= 32.04g, CO= 28.01g)

Which process does not require the presence of a physical substance in order to transfer heat? air in the atmosphere is heated by the ground. this warm air then rises, and cooler air falls. this is an example of what type of process? how is conduction different from radiation?
