Explanation:

(a) Matter cannot be created and destroyed by a chemical reaction. (correct)

The number and type of atoms entering the chemical reaction are the same with the number and type of atoms leaving the chemical reaction.

(b) The reactants are the same substance as the products. (wrong)

You may see in the reaction that we have as reactants zinc and hydrochloric acid which react to form the products, zinc chloride and hydrogen.

(c) The number of molecules in the reactants are equal to the number of molecules in the products. (wrong)

As reactants we have 2 hydrochloric acid (HCl) molecules and as products 1  hydrogen (H₂) molecule. Zn is a metal and ZnCl is a salt.

(d) The atoms on the reactants side are changed into different atoms on the products side. (wrong)

The number and type of atoms entering the chemical reaction are the same with the number and type of atoms leaving the chemical reaction.

Describe the term molarity as it relates to an acid or base.
Sidana [21]
Molarity is expressed as the number of moles of solute per volume of the solution. For example, we are given a solution of 2M NaOH this describes a solution that has 2 moles of NaOH per 1 L volume of the solution. Acids and bases can be measured through the concentrations of H+ and OH- ions in units of molarity. Hope this helps.

How many moles of K2SO4 are in 15.0 grams of K2SO4
uysha [10]
Molar mass K₂SO₄ = 174.259 g/mol

n =  \frac{m}{M}

n =  \frac{15.0 g}{174.259g/mol}

n = 0.0860 moles

hope this helps!
