Answer:
Explanation:
The half reactions are:
Mg → Mg²⁺
+ 2e⁻
2H⁺ + 2e⁻ → H₂
The first equation is an oxidation half while the second is a reduction half. To get the overall reaction equation, we simply combine the two equations. The reactants combines at the left hand side with the products comes together at the right hand side.
Mg + 2H⁺
+ 2e⁻ → Mg²⁺
+ 2e⁻ + H₂
Now we cancel out the species that appear on both sides:
Mg + 2H⁺
→ Mg²⁺
+ H₂

Answer:
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Answer: 1.5
Explanation:
The acid, HCIO4 ionizes to give hydrogen ion (H+) and a conjugate base as follows:
HCIO4(aq) <---> H+(aq) + CIO4-(aq)
Hence, the H+ has also have a concentration of 0.0282 M
Mathematically, pH is expressed as:
pH = -log(H+), where H+ is the concentration of hydrogen ion.
So, for HCIO4
pH = - log (0.0282 M)
pH = - (-1.5497) (The two minus signs will cancel out)
pH = 1.5497
Round the pH value to the nearest tenth as 1.5
Thus, the pH of 0.0282 M of HCIO4 is 1.5, also HCIO4 is strongly acidic since pH values less than 7 are regarded as acidic.
