Answer:
We will derive the combined gas equation from the law of Gases
Boyle's law
P∝1/V
PV=Constant
Charles law
V∝T
Avogadro's Law
V∝n
By combining these three equations we get the combined gas equation
PV=nRT
V=nRT/P
If n=1 mole
V=RT/P
By putting the value of R, T, and P in the above equation we can calculate the volume of the gas at STP.
Answer:
50L of H2
Explanation:
First let us generate a balanced equation for the reaction
Cl2 + H2 —> 2HCl
From the equation above,
1L of Cl2 required 1L of H2 for complete reaction.
Therefore, 50L of Cl2 will also require 50L of H2 for complete reaction.
Because it is balanced with protons and electrons
Answer:
as no. of protons is equals to the no. of electrons so, it is a neutral atom.
but, as Atomic No. = Mass No. - No. of neutrons
Atomic No. = No. of protons = 18
so, Mass No. = Atomic No. + No. of Neutrons= 18 + 20 = 38
so, correct option is C.
