Which of the following is true about the products formed during photosynthesis? a. they have the same mass as the mass of reactants. b. they are the same set of compounds as the reactants. c. they have more mass than the mass of reactants. d. they are chemically the same as the reactants.

Option (A) is the correct answer.

Explanation:

According to law of conservation of mass, like energy, mass can neither be created nor it can be destroyed.

It can only be transformed from one form to another.

For example, reaction equation for photosynthesis process is

Mass of 6 = 6 (12 + 32) g/mol = 264 g/mol

Mass of 6 = 6(2 + 16) g/mol = 108 g/mol

Mass of = 180 g/mol

Mass of 6 = 192 g/mol

Therefore, total mass of the reactants is 372 g/mol and the mass of products is 372 g/mol.

Thus, we can conclude that the statement, they have the same mass as the mass of reactants, is true about the products formed during photosynthesis.

explanation:

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
