A student made a graph to show the chemical equilibrium position of a reaction. The student forgot to label the y-axis of the gr

aph.
What best explains the label that the student should use on the y-axis?

Reaction rate, as the rate of forward and back reaction become equal at equilibrium.

Reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases with time.

Concentration, as the concentration of products decreases and that of reactants increase over time.

Concentration, as the concentrations of reactants and products remain constant after equilibrium is reached.

A 1-g sample of the compound hydrogen chloride was analyzed and found to be 2.74 percent hydrogen and 97.3 percent chlorine. Wha
inna [77]

Answer:

2.74 percent hydrogen and 97.3 percent chlorine are in 2 g of compound.

The same as initial

Explanation:

HCl → H⁺ + Cl⁻

2.74% H means that in 100 g of compund, 2.74 grams are H

97.3 % Cl means that in 100 g of compound, 97.3 grams are Cl

So how many grams of H and Cl, are in 1 g of compound

100 g ___ 2.74 g are H _____ 97.3 g are Cl

1g _____ 2.74/100 ____ 97.3/100

0.0274 g are H

0.973 g are Cl

In 2 grams we will find

0.0274 g .2 = 0.0548 g of H

0.973 g .2 = 1.946 g of Cl

(grams / total grams) . 100 = %

(0.0548/2 ) .100 = 2.74%

(1.946 /2) .100 = 97.3%
