They are called equivalent sets
A beta particle is the same as B. An electron. This is termed as such for a specific beta radioactive decay reaction.
Number of atoms = moles of magnesium x 6.02x10^23
= 5x6.02x10^23
= 3.01x10^24 atoms.
Hope this helps!
Answer:
Empirical formula for the oxide is P₂O₃
Explanation:
Oxides from P, are:
P₂O; P₂O₃; P₂O₅; P₂O₇; P₄O₆; P₄O₁₀
The reaction is:
P₄ + 3O₂ → P₄O₆
Ratio between the white phosphorus and the oxide is 1:1
Molar mass P₄ = 123.89 g/m
Mass / Molar mass = mole
6.5 g/ 123.89 g/m = 0.0524 mole P₄
0.0524 mole of P₄O₆ have been formed.
Molar mass P₄O₆ = 219.89 g/m
Mol . molar mass = mass
0.0524 mole . 219.89 g/m = 11.52 g
Yes it is.hope this helped
