Answer:

A) Carbon dioxide and Oxygen

Explanation:

Percentage of gases in the Planet's atmosphere:

Carbon dioxide = 4 % 
Nitrogen = 72 % 
Oxygen = 24 %

Percentage of gases in the Earth's atmosphere:

Carbon dioxide = 0.036 % (traces)
Nitrogen = 78 % 
Oxygen = 21 %

___________________

On observing the percentage composition of the atmospheres of the two Planets, we get:

The newly discovered planet has more percentage of Oxygen than The Earth.
Percentage of Carbon dioxide is more in the planet than in the Earth
Nitrogen is less in the planet than in the Earth.

___________________

Answer:

What's asked is the name of the gases that are in higher amounts in the atmosphere of the newly discover planet

Therefore,

<h3>A) Carbon dioxide and Oxygen</h3>

The following equation shows the equilibrium in an aqueous solution of ammonia: NH3(aq)+H2O(l)⇌NH4+(aq)+OH−(aq)NH3(aq)+H2O(l)⇌NH

Answer:

c) H2O and OH−

Explanation:

Acids are the species which furnish hydrogen ions in the solution or is capable of forming bonds with electron pair species as they are electron deficient species.

When an acid donates a proton, it changes into a base which is known as its conjugate base.

Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.

The acid and the base which is only differ by absence or presence of the proton are known as acid conjugate base pair.

Thus, for the reaction,

$NH_3+H_2O\rightleftharpoons Nh_4^++OH^-$
