Hi! where are the options?
The role of the carbon dioxide in water is that it has the ability to form an acid in which it has the capacity to react with underground limestones deposits. If it is able to react with the limestone, then it will most likely produce a substance that can be water-soluble.
Explanation:
The given data is as follows.
= 100 mm Hg or = 0.13157 atm
= = (1080 + 273) K = 1357 K
= = (1220 + 273) K = 1493 K
= 600 mm Hg or = 0.7895 atm
R = 8.314 J/K mol
According to Clasius-Clapeyron equation,
0.77815 =
= J/mol
=
= 221.9 kJ/mol
Thus, we can conclude that molar heat of vaporization of substance X is 221.9 kJ/mol.
Explanation:
Start with a balanced equation.
2H2 + O2 → 2H2O
Assuming that H2 is in excess, multiply the given moles H2O by the mole ratio between O2 and H2O in the balanced equation so that moles H2O cancel.
5 mol H2O × (1 mol O2/2 mol H2O) = 2.5 mol O2
Answer: 2.5 mol O2 are needed to make 5 mol H2O, assuming H2 is in excess.
So they can tell what exact species it is.
