carbon has 6 protons and hydrogen has 1 proton
This reaction would produce salt and water- Sodium Sulphate and Water.
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
D. Since it's atomic # is 14 it has 14 electrons and it has 4 valance electrons because it is 4 over.
<h3>
Answer:</h3>
#1. Type of reaction: Single displacement
#2. Balanced equation: Zn + 2HCI → ZnCI₂ + H₂
<h3>
Explanation:</h3>
<u>We are given;</u>
- The equation; Zn+HCI → ZnCI₂ + H₂
Assuming we are required to identify the type of reaction and balance it;
- The reaction is a <u>single displacement reaction.</u>
- Zinc metal displaces hydrogen atom from hydrochloric acid to form a salt, zinc chloride and hydrogen gas.
- To balance the equation, we put coefficients on the reactants and products for the number of atoms of each element to be equal on both sides of the equation.
- In this case, the appropriate coefficients are 1, 2, 1 and 1
- Therefore, the balanced equation will be;
Zn + 2HCI → ZnCI₂ + H₂
Answer:
[H₃O⁺] = 6.31 x 10⁻³ M.
Explanation:
- To find the hydronium ion concentration [H₃O⁺], we can use the relation:
<em>pH = - log[H₃O⁺].</em>
<em></em>
∴ 2.2 = - log[H₃O⁺].
∴ log[H₃O⁺] = - 2.2
<em>∴ [H₃O⁺] = 6.31 x 10⁻³ M.</em>
