The balanced equation for the production of sugars by photosynthesis is shown below.
600, + 6h20 enersy cgh12o6 + 602
carbon dioxide
water
sugar
oxygen
this equation demonstrates the law of conservation of mass because
a.
there is the same number of compounds on the right side of the equation as the left.
b.
there are more oxygen atoms on the right side of the equation than on the left.
c. the sugar molecule on the right has the same mass as the carbon dioxide molecules on the left.
d.
there is the same number of each type of atom on the right side of the equation as the left.

D= there is the same number of each type of atoms on the right side and left side of the equation.

Explanation:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

the answer would be a

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
