1. in a compound, chemical energy is contained in the (1 point)
a. nuclei of the atoms.
b. unbonded electrons.
c. bonds.
d. movement of the electrons.
2. which of the following statements is true about what happens during a chemical reaction? (1 point)
a. bonds of the reactants are broken, and bonds of the products are formed.
b. bonds of the reactants are formed, and bonds of the products are broken.
c. the bonds of both the reactants and the products are broken.
d. the bonds of both the reactants and the products are formed.

1. Potential of a chemical substances to undergo transformation in a chemical reaction is known as chemical energy. The chemical energy is stored in the bonds of chemical compounds.

Hence, in a compound, chemical energy is contained in bonds.

2. The process in which one or more substance known as reactants are converted to one or more completely new substances known as products are formed is known as a chemical reaction.

Hence, during a chemical reaction bonds of the reactants are broken, and bonds of the products are formed.

1.C 2.A are the answer to the following questions.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
