Answer:
A compound
Explanation:
That's the definition — a compound is a substance that has definite properties and constant composition.
Answer is: <span>1.0 mol X left over.
</span>Chemical reaction: X + 2Y → XY₂.
n(X) = 3,0 mol, excess reactant.
n(Y) = 4,0 mol, limiting reagent.
n - amount of substance.
from reaction: n(X) : n(Y) = 1 : 2.
n(X) : 4 mol = 1 : 2.
n(X) = 2 mol, that reacts.
excess of X: 3 mol - 2 mol = 1 mol.
Answer:
Neutral.
Explanation:
Protons have a positive charge. In this problem there are 12.
Electrons have a negative charge. In this problem there are 12.
Neutrons have a neutral charge that isn't relevant tot the overall charge, it can be ignored.
#protons - #e- = charge
12 - 12 = 0
The protons and electrons balance each other out, resulting in a 0 net charge. This means the atom has a neutral charge.
