Question 4(multiple choice worth 4 points)
(0403 mc)
which of the following is not evidence for the law or conservation of mass during cellular respiration?
the total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced
ch2o5 +603-6co2 + 6h2o + energy
the products from cellular respiration are created from the same elements (carbon, oxygen, and hydrogen) that make up the reactants
cellular respiration creates an energy molecule when glucose is broken down

CH2O5 +603-6CO2 + 6H2O + energy isn't the evidence of conservation of mass in cellular respiration.

Option B

Law of conservation of mass states that mass can neither be created nor be destroyed. And this law holds good for all sorts of chemical reactions except the nuclear reactions.

In case of cellular respiration, one molecule of glucose reacts with 6 molecules of oxygen to produce 6 molecules of carbon dioxide and 6 molecules of water and energy. Now this energy that is produced isn't produced in expense of mass, but in expense of chemical bonds that are present in glucose molecules.

Also if we calculate the number of atoms on each side of the reaction, the number of atoms remain same as well as number of atoms of individual elements also remain same.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
