Answer:

it would have 18 neutrons, as a neutral atom has the same number of electrons as protons, therefore the number of protons is 17. 35-17 leaves you with 18 neutrons

The equilibrium constant, Kc , for the decomposition of COBr2 COBr2(g) ↔ CO(g) + Br2(g) is 0.190. What is Kc for the following r
charle [14.2K]

Answer:

2CO(g)+2Br_2(g)\rightleftharpoons 2COBr_2(g)

27.70 is K_c' for the reaction.

Explanation:

COBr_2(g)\rightleftharpoons CO(g) + Br_2(g)

The equilibrium constant of the reaction = K_c=0.190

The expression of equilibrium constant is given by :

K_c=\frac{[CO][Br_2]}{[COBr_2]}..[1]

2CO(g)+2Br_2(g)\rightleftharpoons 2COBr_2(g)

The equilibrium constant expression for above reaction can be written as:

K_c'=\frac{[COBr_2]^2}{[CO]^2[Br]^2}

K_c'=\frac{1}{(K_c)^2} ( from [1])

K_c'=\frac{1}{(0.190)^2}=27.70

27.70 is K_c' for the reaction.

In an acid-base neutralization reaction 38.74 ml of 0.500 m potassium hydroxide (ki) reacts with 50.00 ml of sulfuric acid solut
g100num [7]

Answer: 0.19M

Explanation: 2KOH+H_2SO_4\rightarrow K_2SO_4+2H_2O

Using Molarity equation:

n_1M_1V_1=n_2M_2V_2

M_1 = molarity of acid

V_1 = volume of acid

M_2 = molarity of base

V_2 = volume of base

2\times M_1\times 50ml=1\times 0.500M\times 38.74ml

M_1=0.19M

Thus the concentration of the H_2SO_4 solution is 0.19M.
