Why did the big bang not produce a significant proportion of elements heavier than helium?
Travka [436]

The big bang did not produce a significant proportion of elements heavier than helium because the temperatures and densities present in the early universe were not sufficient to support the fusion of heavier elements.

During the first few minute of the big bang, the universe was composed of mostly hydrogen and helium, with very small amounts of lithium and beryllium. As the universe expanded and cooled, the denser regions of the universe collapsed to form the first stars. Inside these stars, the intense pressure and heat generated by nuclear fusion reactions allowed for the production of heavier elements, such as carbon and oxygen. However, elements heavier than helium, such as iron and nickel, require even higher temperatures and densities to be produced, which can only be found in the cores of supernovae. Therefore, the big bang alone did not produce a significant proportion of elements heavier than helium.

At a certain temperature, the K p Kp for the decomposition of H 2 S H2S is 0.746 0.746 . H 2 S ( g ) − ⇀ ↽ − H 2 ( g ) + S ( g )
Ivanshal [37]

<u>Answer:</u> The total pressure of container at equilibrium is 0.431 bar

<u>Explanation:</u>

We are given:

Pressure of hydrogen sulfide = 0.240 bar

The given chemical equation follows:

                      H_2S(g)\rightleftharpoons H_2(g)+S(g)

<u>Initial:</u>            0.240

<u>At eqllm:</u>      0.240-x        x      x

The expression of K_p for above equation follows:

K_p=\frac{p_{H_2}\times p_S}{p_{H_2S}}

We are given:

K_p=0.746

Putting values in above expression, we get:

0.746=\frac{x\times x}{0.240-x}\\\\x=0.191,-0.940

Neglecting the negative value of 'x' because pressure cannot be negative.

So, the equilibrium pressure of hydrogen gas = x = 0.191 bar

The equilibrium pressure of sulfur gas = x = 0.191 bar

The equilibrium pressure of hydrogen sulfide gas = (0.240 - x) = (0.240 - 0.191) = 0.049 bar

Total pressure of the container at equilibrium = p_{H_2}+p_{S}+p_{H_2S}

Total pressure of the container at equilibrium = 0.191 + 0.191 + 0.049 = 0.431 bar

Hence, the total pressure of container at equilibrium is 0.431 bar

Which of the following free-body diagrams is a balanced force?
sleet_krkn [62]

Answer:

2

Explanation:

#1 is incorrect as there is no upward force that would balance the 5 N downward force

#3 is incorrect 2 is less than 5 = net force downward of 3 N

#4 is incorrect 5 is greater than three = 2 N net force going to the left and 2N going up
