When sodium carbonate reacts with hydrochloric acid, Carbon dioxide gas is released. Pass the gas through calcium hydroxide,the solution turns milky indicating that the gas is Carbon dioxide .

The substance K is hydrochloric acid and this is called as neutralisation.

hope this helps u

At a certain temperature the value of the equilibrium constant, Kc, is 1.27 for the reaction. 2As (s) + 3H2 (g) ⇌ 2AsH3 (g) What
Bess [88]

Answer:

0.887

Explanation:

Hello,

In this case, the law of mass action for the first reaction turns out:

Kc=\frac{[AsH_3]^2}{[As]^2[H_2] ^3}=1.27

Now, for the second reaction is:

Kc=\frac{[As][H_2] ^{3/2}}{[AsH_3]}

Therefore, by applying square root for the first reaction, one obtains:

\sqrt{Kc} =\sqrt{\frac{[AsH_3]^2}{[As]^2[H_2] ^3}} =\sqrt{1.27}

\frac{\sqrt{[AsH_3]^2} }{\sqrt{[As]^2} \sqrt{[H_2] ^3} } =\sqrt{1.27}

\sqrt{1.27}=\frac{[AsH_3]}{[As][H_2] ^{3/2}}

Finally, since Kc is asked for the inverse reaction, one modifies the previous equation as:

Kc'=\frac{1}{\sqrt{1.27} }=\frac{[As][H_2] ^{3/2}}{[AsH_3]}=0.887

Best regards.

Which substance would have the greatest standard molar entropy?<br>NO2(g)<br>N; (g)<br>N20<br>NO20​
Rama09 [41]

Answer:

Option A

Explanation:

Standard molar entropy determines the randomness of a mole of substance. Thus, the larger and complex a molecule is, the larger will be its molar entropy.  

The molar entropy of gases is higher than liquids which is turn is higher than solid.  

Here , NO2 is a gas with higher complex structure (trigonal planar) than N2 (linerar), N2O (linear) and N2O2 (linear)

Hence, NO2(g) will have greatest standard molar entropy  

Option A is correct
