1 answer:
torisob [31]3 years ago
5 0

Answer:

1. 2N₂ + O₂ ---> 2N₂O

2. BaCl₂ + 2NaOH ---> Ba(OH)₂ + 2NaCl

3. H₂SO₄ + 2KOH ----> K₂SO₄ + 2H₂O

4. K₂CO₃ + 2HCl ---> 2KCl + H₂O + CO₂

5. CaCO₃ + 2HNO₃ ---> Ca(NO₃)₂ + H₂O + CO₂

6. Ca + 2H₂O ---> Ca(OH)₂ + H₂

7. Pb(NO₃)₂ + 2NaI ---> PbI₂ + 2NaNO₃

8. Al₂(SO₄)₃ + 6NaOH ---> 2Al(OH)₃ + 3Na₂SO₄

9. Al(OH)₃ + NaOH ---> NaAlO₂ + 2H₂O

10. 2Pb(NO₃)₂ ---> 2PbO + 4NO₂ + O₂

Explanation:

A balanced equation of a chemical reaction is one that has the number of moles of atoms of each element taking part in the reaction equal on both sides of the reaction, that is on the reactants and products sides of the reaction.

The balanced equations of the given reactions is as follows:

1. 2N₂ + O₂ ---> 2N₂O

2. BaCl₂ + 2NaOH ---> Ba(OH)₂ + 2NaCl

3. H₂SO₄ + 2KOH ----> K₂SO₄ + 2H₂O

4. K₂CO₃ + 2HCl ---> 2KCl + H₂O + CO₂

5. CaCO₃ + 2HNO₃ ---> Ca(NO₃)₂ + H₂O + CO₂

6. Ca + 2H₂O ---> Ca(OH)₂ + H₂

7. Pb(NO₃)₂ + 2NaI ---> PbI₂ + 2NaNO₃

8. Al₂(SO₄)₃ + 6NaOH ---> 2Al(OH)₃ + 3Na₂SO₄

9. Al(OH)₃ + NaOH ---> NaAlO₂ + 2H₂O

10. 2Pb(NO₃)₂ ---> 2PbO + 4NO₂ + O₂

t 745 K, the reaction below has an equilibrium constant (Kc) of 5.00 × 102. H2 (g) + I2 (g) ⇌ 2 HI (g) If a mixture of 0.10 mol
spayn [35]

Answer : The concentration of HI (g) at equilibrium is, 0.643 M

Explanation :

The given chemical reaction is:

                        H_2(g)+I_2(g)\rightarrow 2HI(g)

Initial conc.    0.10        0.10      0.50

At eqm.        (0.10-x)  (0.10-x)   (0.50+2x)

As we are given:

K_c=5.00\times 10^2

The expression for equilibrium constant is:

K_c=\frac{[HI]^2}{[H_2][I_2]}

Now put all the given values in this expression, we get:

5.00\times 10^2=\frac{(0.50+2x)^2}{(0.10-x)\times (0.10-x)}

x = 0.0713  and x = 0.134

We are neglecting value of x = 0.134 because the equilibrium concentration can not be more than initial concentration.

Thus, we are taking value of x = 0.0713

The concentration of HI (g) at equilibrium = (0.50+2x) = [0.50+2(0.0713)] = 0.643 M

Thus, the concentration of HI (g) at equilibrium is, 0.643 M
