Answer:

[PH_3]=0.30M but see detailed explanation, please.

Explanation:

Hello there!

In this case, unfortunately, we are not given the rate constant but we can set up a reaction according to the information available on the internet:

4PH_3\rightarrow P_4+6H_2

Whose rate constant is 0.0375/s. In such a way, it is possible infer that this is first-order reaction whose integrated rate law is:

[PH_3]=[PH_3]_0exp(-kt)

Thus, given the initial concentration, rate constant and elapsed time, the final concentration of PH3 would be:

[PH_3]=(0.95M)exp(-30.50s*0.0375/s)\\\\

[PH_3]=0.30M

However, it is important to keep in mind this result may vary according to your actual question.

Regards!

What is the balanced symbol equation for magnesium chloride + sodium carbonate --> magnesium carbonate + sodium chloride
Semenov [28]

Answer:

MgCl₂+ Na₂CO₃ ==> MgCO₃ + NaCl

From a quick observation

You see that the right hand side of the eqn is deficient of Sodium and Chlorine

Simply Add a Coefficient of 2 to NaCl to balance it with the left.

Your answer now becomes

MgCl₂ + Na₂CO₃ ==> MgCO₃ + 2NaCl.✅
