Hello!

In this equation, the element we are working with is C, which is carbon. The number 6 represents the atomic number, and 13 is the atomic mass.

We know that the number of elections are equal to the atomic number, and the number of protons are also equal to the atomic number.

While, the number of neutrons are determined by subtracting the atomic mass by the atomic number.

13 - 6 = 7 neutrons

Therefore, there are 6 protons, 6 electrons, and 7 neutrons.

Pick C Because it's

Explanation:

a chemical reaction in which one element replaces another in a compound. F₂ + 2NaCl → 2NaF + Cl₂, where F replaces Cl in NaCl. A double-replacement reaction is a reaction in which the metals in two ionic compounds exchange partners.

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]

Answer: The total pressure of container at equilibrium is 0.431 bar

Explanation:

We are given:

Pressure of hydrogen sulfide = 0.240 bar

The given chemical equation follows:

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

Initial: 0.240

At eqllm: 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

What caused wind to blow

Arlecino [84]

Answer:

Different atmospheric pressure. When there is a different atmospheric pressure, air moves from the higher pressure to the lower pressure area which results in what you call WIND but can result in various speeds and pressure.

What are the affects of coffee for an average 12 year old?

lord [1]

Most young children already have plenty of energy without the need for coffee to sustain them throughout the day, so at least until they are 12 years old, it's best to avoid giving your kids coffee if possible
