A. an ion
The atom gains a net electrical charge if the number of protons and electrons are not equal which makes it an ion.
H₂SO₄ + Ba(OH)₂ -----> BaSO₄ + 2H₂O
Coefficient for sulfuric acid: 1
Propylethylene would be the answer
Answer:
105.8 g of Na would be required
Explanation:
Let's think the reaction:
2Na(s) + Cl₂(g) → 2NaCl (s)
1 mol of chlorine reacts with 2 moles of sodium
Then, 2.3 moles of Cl₂ would react with (2.3 .2) / 1 = 4.6 moles
Let's determine the mass of them.
4.6 mol . 23 g/mol = 105.8 g
