Which statement is correct about the total mass of carbon dioxide and water used during photosynthesis? it is equal to the mass of glucose used. it is less than the mass of oxygen used. it is equal to the mass of glucose formed. it is greater than the mass of oxygen formed.

It is greater than the mass of oxygen formed.

Explanation:

Photosynthesis is the process of using light energy to convert carbon dioxide and water to glucose and oxygen.

6CO₂ + 6H₂O ⟶ C₆H₁₂O₆ + 6O₂

Mass of CO₂ + H₂O = mass of C₆H₁₂O₆ + 6O₂

Subtract the mass of glucose from the right-hand side but not the left. Then

Mass of CO₂ + H₂O > mass of O₂

A is wrong, because glucose is formed, not used.

Bb is wrong, because oxygen is formed, not used.

C is wrong, because the total mass of reactants is greater than just one of the products.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
