The balanced equation for photosynthesis is shown below. 6 co2 + 6 h2o → c6h12o6 + 6 o2 which statement best justifies the conservation of mass during photosynthesis? the total number of carbon atoms on both sides is 6. the total number of hydrogen atoms on both sides is 18. the number of oxygen atoms is equal to the number of carbon atoms on each side. the number of oxygen atoms is equal to the number of hydrogen atoms on each side.

The total number of carbon atoms on both sides is 6.

Explanation:

The law of conservation of mass or the Lavoisier's law is a fundamental law of natural sciences. According to this law, in an isolated system, during any ordinary chemical reaction, the total mass in the system remains constant.

The law of the conservation of mass is the base of the balancing of the chemical equations, since according to it, the consumed mass of the reactants is equal to the mass of the obtained products.

In the following table are the amount of C, H and O in the reagents and products of the reaction in question,

        Reagents     Products

C            6                 6

H            12                12

O            18                18

As you can see, the statement that best justifies the conservation of mass during photosynthesis is the one that says that the total number of carbon atoms on both sides is 6.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
