Which statement describes a chemical reaction? · atoms in the products are rearranged to form new substances · atoms in the reactants are rearranged to form new substances · atoms in the products change into new atoms to form new substances · atoms in the reactants change into new atoms to form new substances

The answer to this is B

A chemical reaction is defined as the process in which the reareangements of molecular or iconic structure of a substance happens. In a chemical reaction there is not always a physical change or a nuclear reaction. Based on this we say that the reactants in a chemical reaction are rearranged to create new susbtances. The atoms in itself do not change simply rearrange or move about if they were to change then it would be a different starting material.

The answer for this question is d. none of these

The correct answer is c. orbital shape. "the angular momentum quantum number l describes the shape of an orbital. it corresponds to each orbital type, i.e. (0,1,2,−1)=(s,p,d,f,g,"
