You would have to use the ideal gas law: PV = nRT where,
P = pressure
V = volume
n = moles
R = universal gas constant for a specific pressure (in this case it's 62.364 torr)
T = temperature in Kelvin
First, convert Celsius to kelvin by adding 273 to 25, which gives you 298K
Now plug in your variables to find n:
(800 torr)(1.25 L) = n(62.364)(298K)
1000 = 18584.472n
Now divide 1000 by 18584.472 to get n:
1000/18584.472 = 0.054 moles
Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.
The oxidation number of Fe in Fe(NO3)2 is +3.
Answer:
The volume of water vapor increases.
Explanation:
Pressure, concentration, and temperature all affect the equilibrium position of chemical reactions in a closed system such as this one. Increasing HCl increases the pressure in the system. It favors the forward's reaction because this favors a reduced overall pressure in the system. The products have a combined 3 moles of gases while the reactants have a combined 5 moles of gases.
The answer would be D. Hope this helps
