Explanation:

What is the purpose of the scientific method?

<em><u>ans/</u></em>

the goal of any scientific method is to solve a problem or to better understand an observed event.

b.

i. What does the law of conservation of energy say?

<em><u>ans/</u></em>

The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.

ii. List two different kinds of energy.

<em><u>ans/</u></em>

Potential energy.

Kinetic energy.

iii. What does the law say about changes energy can undergo?

<em><u>ans/</u></em>

The implication of the Law of Conservation of Energy is that for any energy conversion, if a certain type, or form, of energy gets reduced by a certain amount, then another type of energy must increase by the same amount.

Answer:

ii. Purpose of scientific method

=The Scientific Method helps you put together experiments, use data to find conclusions and interpret them. In short, the Scientific Method is a step-by-step process: First, observe. Use your senses and take notes about the situation

For the equilibrium
Mamont248 [21]

Answer:

Equilibrium concentrations of the gases are

H_2S=0.596M

H_2=0.004 M

S_2=0.002 M

Explanation:

We are given that  for the equilibrium

2H_2S\rightleftharpoons 2H_2(g)+S_2(g)

k_c=9.0\times 10^{-8}

Temperature, T=700^{\circ}C

Initial concentration of

H_2S=0.30M

H_2=0.30 M

S_2=0.150 M

We have to find the equilibrium concentration of gases.

After certain time

2x number of moles  of reactant reduced and form product

Concentration of

H_2S=0.30+2x

H_2=0.30-2x

S_2=0.150-x

At equilibrium

Equilibrium constant

K_c=\frac{product}{Reactant}=\frac{[H_2]^2[S_2]}{[H_2S]^2}

Substitute the values

9\times 10^{-8}=\frac{(0.30-2x)^2(0.150-x)}{(0.30+2x)^2}

9\times 10^{-8}=\frac{(0.30-2x)^2(0.150-x)}{(0.30+2x)^2}

9\times 10^{-8}=\frac{(0.30-2x)^2(0.150-x)}{(0.30+2x)^2}

By solving we get

x\approx 0.148

Now, equilibrium concentration  of gases

H_2S=0.30+2(0.148)=0.596M

H_2=0.30-2(0.148)=0.004 M

S_2=0.150-0.148=0.002 M
