Read the chemical equation. N2 + 3H2 → 2NH3 Using the volume ratio, determine how many liters of NH3 is produced if 1.2 liters o
zmey [24]

Answer : The volume of NH_3 produced will be, 0.8 liters.

Explanation : Given,

Volume of H_2 = 1.2 L

At STP, 1 mole of substance contains 22.4 L volume of substance.

The given balanced chemical reaction is:

N_2+3H_2\rightarrow 2NH_3

From the balanced chemical reaction we conclude that,

As, 3\times 22.4L volume of H_2 produced 2\times 22.4L volume of NH_3

So, 1.2L volume of H_2 produced \frac{2\times 22.4L}{3\times 22.4L}\times 1.2L=0.8L volume of NH_3

Therefore, the volume of NH_3 produced will be, 0.8 liters.

Given that the Ksp value for Ca3(PO4)2 is 8.6×10−19, if the concentration of Ca2+ in solution is 4.9×10−5 M, the concentration o
nasty-shy [4]

Answer:

.0027 M

Explanation:

We must calculate the threshold concentration of PO3−4 using Ksp and the given concentration of Ca2+:

Ca3(PO4)2(s)⇌3Ca2+(aq)+2PO3−4(aq)

Ksp=8.6×10−19=[Ca2+]3[PO3−4]2=(4.9×10−5M)3[PO3−4]2

[PO3−4]=0.0027 M

At a given temperature, the elementary reaction A − ⇀ ↽ − B , in the forward direction, is first order in A with a rate constant
ZanzabumX [31]

Answer:

0.24

Explanation:

We are given that

Rate constant for A=k=0.0180/s

Rate constant for  B,k'=0.0750/s

We have to find the value of equilibrium constant for the reaction

A\rightleftharpoons B

Equilibrium constant, for k=\frac{k}{k'}

Using the formula

k=\frac{0.0180}{0.0750}=0.24

Hence, the value of the equilibrium constant for the reaction

A\rightleftharpoons B at this temperature=0.24
