Consider the reaction.
vovangra [49]

Answer: The value of Keq for the reaction expressed in scientific notation is  1.6\times 10^{-5}

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios.

For the given chemical reaction:

2NOCl(g)\rightarrow 2NO(g)+Cl_2(g)

The expression for K_{eq} is written as:

K_{eq}=\frac{[NO]^2\times [Cl_2]}{[NOCl]^2}

K_{eq}=\frac{(1.2\times 10^{-3})^2\times (2.2\times 10^{-3})}{(1.4\times 10^{-2})^2}

K_{eq}=1.6\times 10^{-5}

The value of Keq for the reaction expressed in scientific notation is  1.6\times 10^{-5}

A piece of unknown solid substance weighs 437.2 g, and requires 8460 J to increase its temperature from 19.3 °C to 68.9 °C.What
Pachacha [2.7K]

Answer:

0.3832

Explanation:

Givens

m = 437.2 grams

c = ?

delta t = 69.8 - 19.3

H = 8460 J

Formula

H = m*c*Δt

Solution

8460 = 437.2 * c * (69.8 - 19.3)

8460 = 437.2 * c * 50.5

8460 = 22078.6 * c

c = 8460 / 22078,6

c = .3832 J / (oC * gr)
