Answer:
Mg(ClO₃)₂ ⟶ MgCl₂ + 3O₂
Explanation:
The reaction gives magnesium chloride and oxygen.
The balanced equation is then
Mg(ClO₃)₂ ⟶ MgCl₂ + 3O₂
A is <em>wrong</em>, because it is not balanced (12 O atoms on left and 6 O atoms on right).
C and D are <em>wrong</em> because they have the reactants as products and vice versa.

Answer:
1.758 x 10⁻¹¹.
Explanation:
∵ pH = - log[H⁺].
∴ 5.47 = -log[H⁺].
log[H⁺] = -5.47.
∴ [H⁺] = 3.388 x 10⁻⁶ M.
∵ [H⁺] = √(Ka.C)
∴ [H⁺]² = Ka.C
<em>∴ Ka = [H⁺]²/C </em>= (3.388 x 10⁻⁶)²(0.653) = <em>1.758 x 10⁻¹¹.</em>
Answer: The answer is critical point
Explanation:
Took the quiz and got it right
Since Cl2O3 is a neutral compound, it has an overall charge of 0, which means that the total oxidation number of the compound is 0.
O has an oxidation number of 2- so, 3(2-)= 6-
to have an overall charge of 0, 6+ shpuld be added. Since there are 2 Cl's 6/2=3
Oxidation number of Cl is 3+
