Consider the reaction below. At 500 K, the reaction is at equilibrium with the following concentrations. [PCI5]= 0.0095 M [PCI3]
Dmitriy789 [7]

Answer: The equilibrium constant for the given reaction is 0.0421.

Explanation:

PCl_5\rightleftharpoons PCl_3+Cl_2

Concentration of [PCl_5] =  0.0095 M

Concentration of [PCl_3] =  0.020 M

Concentration of [Cl_2] =  0.020 M

The expression of the equilibrium constant is given as:

K_c=\frac{[PCl_3][Cl_2]}{[PCl_5]}=\frac{0.020 M\times 0.020 M}{0.0095 M}

K_c=0.0421 (An equilibrium constant is an unit less constant)

The equilibrium constant for the given reaction is 0.0421.

How many atoms of hydrogen are found in the compound, NH4C2H302?
Mariulka [41]
<h2>Answer:</h2>

7 hydrogen atoms

<h2>Explanation:</h2>

N<em><u>H4</u></em>C2<em><u>H3</u></em>02

In this problem we see the hydrogen atom twice, along with the numbers 4 and 3 next to them. (as shown above in bold & underlined)

So, in order to find how many there are in all you add both hydrogen atoms together-

H4+H3= H7

therefore, there are 7 hydrogen atoms in all
