Number of moles

Explanation:

Using the number of moles in chemical reactions, we can determine the quantity of products and even the reactants that are combining to form them.

The number of moles is derived using the expression below is;

     Number of moles  = \frac{mass}{molar mass}

Once we establish the number of moles of any of the specie given from the mass and molar mass, we can relate it to any other species.

Wear _______________________ when handling batteries, because they can explode or leak.
Basile [38]

The answer is: b. Safety glasses and acid-resistant gloves.

Battery acid (sulfuric acid) has pH = 0.

Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).

Chemical dissociation of sulfuric acid in water:  

H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).  

Sulfuric acid can come in contact with eyes and hands, so it is important to wear safety glasses and acid-resistant gloves.
