How could energy conservation to control or decrease air, water, and land pollution?

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %

Determine type of reaction & predict the product c3h12+o2 =

Calculate the temperature rise when 0.2g of propane is used to heat 400cm cubed of water.
