Answer:
The given equation is not balanced.
Explanation:
Chemical equation:
3H₂ + 3Cl₂ → HCl
The balanced equation always have equal number of atoms on both side of equation. In this equation on left side there are six atoms of chlorine and six atoms of hydrogen are present while on right side only one atom of hydrogen and one atom of chlorine are present.
The balanced equation always follow the law of conservation of mass.
According to the law of conservation of mass, mass can neither be created nor be destroyed in a chemical reaction.
It means reactant and product always have same mass.
The given equation can written as balanced equation as follows,
Balanced chemical equation:
3H₂ + 3Cl₂ → 6HCl
There are equal number of atoms of hydrogen and chlorine are present on both side of equation so it follow the law of conservation of mass.
Answer:
+5
Explanation:
The oxidation number of phosphorus can be obtained as follows:
H4P2O7 = 0
4(+1) + 2P + 7(—2) = 0
4 + 2P —14 = 0
Collect like terms
2P = 14 — 4
2P = 10
Divide both side by 2
P = 10/2
P = +5
The oxidation number of phosphorus is +5

Answer:
270
Explanation:
Once you add more mass to something the mass doesn’t go away you add more mass.
