Answer:
C. Parents can pass on useful traits to offspring
Explanation:
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
Answer:
False
Explanation:
This is false. It's not sulfide but sulphate. Sulphide is the combination of oxygen and Sulphur. This equation only consists of aluminum and Sulphur. There isn't any oxygen so it's sulphate.
For example, carbon and oxygen equals to carbon dioxide
but if the above equation had carbon and Sulphur then the result would be aluminum sulphide.
aluminum + sulphur ---> aluminium sulphate (Al2SO4)
