Consider the reaction. PCl5(g)↽−−⇀PCl3(g)+Cl2(g) K=0.042 The concentrations of the products at equilibrium are [PCl3]=0.18 M and
tatyana61 [14]

<u>Answer:</u> The equilibrium concentration of PCl_5 is 1.285 M.

<u>Explanation:</u>

The chemical equation for the decomposition of phosphorus pentachloride follows:

PCl_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)

The expression for equilibrium constant is given as:

K_c=\frac{[PCl_3][Cl_2]}{[PCl_5]}

We are given:

K_c=0.042

[PCl_3]=0.18M

[Cl_2]=0.30M

The concentration of solid substances are taken to be 1. Thus, they do not appear in the equilibrium constant expression.

Putting values in above equation, we get:

0.042=\frac{0.18\times 0.30}{[PCl_5]}

[PCl_5]=1.285

Hence, the equilibrium concentration of PCl_5 is 1.285 M.

Identify the type of reaction depicted below:<br> 2SO2(g)<br> +<br> O2(g) --&gt; 2SO3(g)
ioda

Answer:

Combination reaction

Explanation:

In Chemistry, elements and compounds are involved in a process called chemical reactions, which are of different types namely: combination, decomposition, double replacement, combustion etc. A combination reaction is that reaction in which two or more substances called the REACTANTS combine together to form a single new substance called the PRODUCT.

In this case, a reaction is depicted as follows:

2SO2(g) + O2(g) --> 2SO3(g)

In this reaction, compound SO2 combines chemically with element O2 to form a single new compound SO3. Hence, this is a type of COMBINATION REACTION.

7. Lawrencium has a half-life of 3.00 minutes. I started with a 100.0 g sample. After 45.0 minutes how
Zinaida [17]

Answer:

N=3.05*10^-3g

Explanation:

Using Ln(No/N)=0.693/t½*t

Ln(No/N)=0.693/3*45

No/N=exp(10.396)

100/exp(10.396)=N

100/32695.7=N

N=3.05*10^-3g
