Answer:
The answer to your question is 1.36 moles of P₂O₅
Explanation:
Data
moles of P₂O₅ = ?
moles of O₂ = 3.4 moles
Balanced chemical reaction
4P + 5O₂ ⇒ 2P₂O₅
To solve this problem use proportions and cross multiplication. Consider the coefficients of the molecules of the balanced equation.
5 moles of O₂ --------------- 2 moles of P₂O₅
3.4 moles of O₂ ------------ x
x = (3.4 x 2) / 5
-Simplification
x = 6.8 / 5
-Result
x = 1.36 moles of P₂O₅

Answer:
The atomic nucleus is the small, dense region consisting of protons and net at the center of an atom.
Explanation:
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. ... Protons and neutrons are bound together to form a nucleus by the nuclear force.

Hello!
Three nails have a mass of 3.05 g. How many moles of iron do they contain?
Data:
3 nails of iron = 3.05 g (by nail)
The atomic mass of iron is 55.845 amu, so the molar mass is:
M = 55.845 → M ≈ 56 g / mol
With a simple 3 rule:
56 g → 1 mol
3.05 g → y mol
Therefore:
Soon:
3 nails → 3*0.05446 = 0.1638 moles (answer)
