Answer: 317 joules

Explanation:

The quantity of heat energy (Q) gained by aluminium depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

In this case,

Q = ?

Mass of aluminium = 50.32g

C = 0.90J/g°C

Φ = (Final temperature - Initial temperature)

= 16°C - 9°C = 7°C

Then, Q = MCΦ

Q = 50.32g x 0.90J/g°C x 7°C

Q = 317 joules

Thus, 317 joules of heat is gained.

If you want to prepare 5 liters of a 0.35m solution of nh4cl, how many grams of salt
harina [27]
Answer is: mass fo ammonium chloride is 93.625 grams.
V(NH₄Cl) = 5 L.
c(NH₄Cl) = 0.35 M.
n(NH₄Cl) = V(NH₄Cl) · c(NH₄Cl).
n(NH₄Cl) = 5 L · 0.35 mol/L.
n(NH₄Cl) = 1.75 mol.
M(NH₄Cl) = 14 + 1·4 + 35.5 · g/mol = 53.5 g/mol.
m(NH₄Cl) = n(NH₄Cl) · M(NH₄Cl).
m(NH₄Cl) = 1.75 mol · 53.5 g/mol.
m(NH₄Cl) = 93.625 g.

nekit [7.7K]

<u>Answer:</u> The relation between the forward and reverse reaction is K_f=\frac{1}{K_r}

<u>Explanation:</u>

For the given chemical equation:

2NH_3(g)\rightleftharpoons N_2 (g)+3H_2(g)

The expression of equilibrium constant for above equation follows:

K_f=\frac{[N_2][H_2]^3}{[NH_3]^2}         .......(1)

The reverse equation follows:

N_2 (g)+3H_2(g)\rightleftharpoons 2NH_3(g)

The expression of equilibrium constant for above equation follows:

K_r=\frac{[NH_3]^2}{[N_2][H_2]^3}       .......(2)

Relation expression 1 and expression 2, we get:

K_f=\frac{1}{K_r}

Hence, the relation between the forward and reverse reaction is K_f=\frac{1}{K_r}
