What is the balanced ionic equation for the reaction HCHO2 (aq) + KOH (aq)

Chemistry
1 answer:
aliya0001 [1]3 years ago
3 0
<h3>Answer:</h3>
  • The complete ionic equation is;

H⁺(aq)CHO₂⁻(aq) + K⁺(aq) OH⁻(aq) → K⁺(aq) CHO₂⁻(aq) + H₂O(l)

  • Net ionic equation is;

H⁺(aq) + OH⁻(aq) → H₂O(l)

<h3>Explanation:</h3>
  • The balanced equation for the reaction between HCHO₂ and  KOH is given by;

HCHO₂(aq) + KOH(aq) → KCHO₂(aq) + H₂O(l)

  • Ionic equation involves writing a balanced equation showing all the ions in a chemical reaction.
  • The complete ionic equation will therefore be;

H⁺(aq)CHO₂⁻(aq) + K⁺(aq) OH⁻(aq) → K⁺(aq) CHO₂⁻(aq) + H₂O(l)

  • Net ionic equation on the other hand, shows only the ions that are directly involved in the reaction and omits the spectator ions.
  • The net ionic equation will be;

H⁺(aq) + OH⁻(aq) → H₂O(l)

As the temperature of a fixed volume of a gas increases the pressure wil
Sati [7]

Answer:

As the temperature of a fixed volume of a gas increase the pressure will increase.

Explanation:

According to the Gay- Lussac's Law,

" The pressure of given amount of gas is directly proportional to the temperature at a constant volume"

Mathematical expression:

           P ∝ T

          P = CT

          P / T = C

As the temperature increase, the pressure also increase.

The initial and final expression of volume and pressure can be written as,

P₁ / T₁  = P₂ / T₂

Which is the limiting reactant if we start with 30.0 g Al and 30.0 h O2​
lorasvet [3.4K]

Al

Explanation:

The limiting reactant will be Al:

        4Al + 3O₂ → 2Al₂O₃

The limiting reactant is the reactant in short supply in a chemical reaction.

     Given parameters:

  Mass of Al = 30g  Molar mass = 27g/mol

         Number of moles = \frac{mass}{molar mass} =  \frac{30}{27}

         Number of moles of Al = 1.111 mole

  Mass of O₂ = 30g, molar mass = 32g/mol

   Number of moles =  \frac{30}{32} = 0.94mol

In the reaction:

          4 moles of Al reacted with 3 moles of O₂

         1.11moles of Al will require \frac{1.11 x3}{4} = 0.83mole to react

But we have been given 0.94mole of O₂. This is more than required.

Therefore O₂ is in excess and Al is the limiting reactant.
