2c6h5cooh + 15o2 → 14co2 + 6h2o which of the following options gives the correct product: product ratio? co2: h2o = 14: 6 co2: h2o = 6: 14 co2: h2o = 1: 1 o2: h2o = 15: 6

The products of the reaction are the molecules on the right, thus water and carbon dioxide, hence we eliminate choice 4. Every time the reaction takes place, 14 molecules of CO2 are created and 6 molecules of H2O by the stoicheiometry of the reaction. This ratio will remain throughout the whole reaction, however many reactants are used up. Hence, the correct ratio is CO2:H2O=14:6, answer a).

Yapo 13 fool coming at you for it

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
