Answer:- C. 16.4 L
Solution:- The given balanced equation is:

From this equation, there is 2:1 mol ratio between HCl and hydrogen gas. First of all we calculate the moles of hydrogen gas from given grams of HCl using stoichiometry and then the volume of hydrogen gas could be calculated using ideal gas law equation, PV = nRT.
Molar mass of HCl = 1.008 + 35.45 = 36.458 gram per mol
The calculations are shown below:

= 
Now we will use ideal gas equation to calculate the volume.
n = 0.672 mol
T = 25 + 273 = 298 K
P = 101.3 kPa = 1 atm
R = 
PV = nRT
1(V) = (0.672)(0.0821)(298)
V = 16.4 L
From calculations, 16.4 L of hydrogen gas are formed and so the correct choice is C.
The answer to your proposed question is Neutron. This is because the atomic mass unit of a neutron is 1 and so it would contribute to the overall mass of the atom.
I hope this answer helped you!
water vapor>liquid water> ice is the correct order of increasing standard molar entropy.
Since water has more entropy than ice, melting is encouraged by entropy. However, ice has less energy than water, which means that energy favors freezing. The distinction between liquid water, ice, and water vapor is that each of them is a different state of matter. Ice represents the solid state, liquid water the liquid state, and water vapor the gaseous state of water. As a result, the system's entropy reduces. A vapour condensing is an exothermic process. Consequently, the environment's entropy rises. however, the environment's growth in entropy grows. Since the gas state has a higher entropy than the liquid state does, the entropy change for the vaporization of water is positive.
