Answer:
The first option
Explanation:
H2O's notation tells us the compound has 2 hydrogen atoms and 1 oxygen atom.
Atomic number of F = 9.
Atomic number of Na = 11.
Atomic number of F + Atomic number of Na = 9+11 = 20
Atomic number of Ca = 20
Therefore the atomic number of F plus the atomic number of Na equals the atomic number of Ca.
Hope this helps you, have a great day ahead!
Answer:
2 mol of SO3 produces 1 mol O2
3 mol SO3 produces 3/2 mol of O2
so O2 produced = 1.5(32) =48 gm
Explanation:
Answer:
174.402 Torr is the partial pressure of oxygen gas.
Explanation:
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.
where,
= Total pressure
= partial pressure of gas-1
= partial pressure of gas-2
= partial pressure of gas-3
= partial pressure of nth gas in the mixture
We have:
Now put all the given values is expression, we get the partial pressure of the gas.
174.402 Torr is the partial pressure of oxygen gas.
