Explanation:
<span>The answer is - a. Alkali Metal.
</span>They react violently with water to form alkaline solutions. This is because they all have 1 electron in their outer shell and losing 1 electron allows them to have full outer shells, and achieve stability.

Answer:
BaCl₂ and H₂SO₄
Explanation:
The reaction is the precipitation of BaSO₄ from solution.
This means that our reactants must contain the Ba ion and SO₄²⁻ ion. The reactants that meet this criteria are the; BaCl₂ aand H₂SO₄
The reaction is given as;
BaCl₂ + H₂SO₄ --> BaSO₄ + 2HCl
Answer:
5.559*10^(23) atoms
Explanation:
Molar Mass of Al(OH)3 = 78 g/mol
(72g/78g/mol)*(6.022*10^(23)atoms/mol) = 5.559*10^(23) atoms in 72 grams of Al(OH)3
