Answer:
The volume of hydrochloric acid increases.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
- Increasing the volume of water vapors:
will increase the the concentration of the products side, so the reaction will be shifted to the left side (backward) to suppress the increase in the concentration of water vapors by addition.
So, The volume of hydrochloric acid increases, the rate of backward reaction increases, the rate of forward reaction decreases, and the volume of chlorine decreases.
<em>So, the right choice is: The volume of hydrochloric acid increases.</em>

Answer:
Mass of Fe = 32.55 g
Explanation:
Molar Mass of Fe atom = 55.845 g/mol
It means,
1 mole of Fe contains = 55.845 g ..............(1)
From mole concept,
<u>1 mole </u>of Fe contain =
atom ..........(2)
Replace 1 mole in equation (2) by 55.845 g , it become :
55.845 g of Fe contain =
atoms
Reverse the equation now
atoms of Fe contain =55.845 g
1 atom of Fe contain =
g
atom contain =
![\frac{55.845}{6.022\times 10^{23}}\times 3.51\times 10^{23}](https://tex.z-dn.net/?f=%5Cfrac%7B55.845%7D%7B6.022%5Ctimes%2010%5E%7B23%7D%7D%5Ctimes%203.51%5Ctimes%2010%5E%7B23%7D)
on calculation,
atom contain = 32.55 g of Fe
Mass of Fe = 32.55 g
<span>using the law pv=nrT and equating these you get the equation v1/t1 = v2/t2 since pressure is constant it also cancels with n and r. show that v1=36.4, t1 = 25 + 273.15 and t2 = 88 +273.15. 273.15 is the Kelvin conversion. then solve for v2. This is 44.1 L.</span>
