Upper N upper H subscript 4 upper C l (s) right and left arrows stacked above each other upper N upper H subscript 3 (g) plus upper H upper C l (g)
Explanation:
The given equation is;
NH₄Cl ⇄ NH₃ + HCl
This equation is clearly different from the other ones.
- In the reactant going forward, there is a right and left arrows stacked above each other.
- The symbol is ⇄ and it is used to show reversibility of chemical reactions.

Answer:
Both
Explanation:
The combined gas law is also known as the general gas law.
From the ideal gas law we assume that n = 1;
So;
PV = nRT
and then;
=
If we cross multiply;
P₁V₁T₂ = P₂V₂T₁
So;
T₁ =
Also;
V₂ =
So from the choices both are correct
Answer:
interests center around the physics and chemistry of the terrestrial planets, in particular, as it relates to their origin and early evolution.
Explanation:
For the rocket engine a lean or excessively rich air-fuel ratio will lead to a compromise in the power output and ultimately the altitude the rocket will reach. Hence which ever the ratio the altitude is greatly affected, unless the ideal ratio is archived.
The air-fuel ratio is the ratio of the amount of air need to burn a part of fuel in a combustion cycle, the ratio is basically a compromise between fuel economy and optimum power output.
For a gasoline engine for example, the ideal air-fuel mixture of 14.7 parts air to 1 part fuel.
