Answer:
5 .04 percent.
Explanation:
it is also known as sulfur dioxide. so it's 5.0.4 percent.
Balanced chemical reaction: C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(g).
<span>There are same number
of atoms of on both side of balanced chemical reaction: ten oxygen atoms, three carbon atoms and eight hydrogen atoms.
</span>Carbon is oxidized and oxygen is reduced in this balanced chemical reaction of combustion of propane.
Answer:
Hydrogen and chlorine need to be balanced. There is an equal amount of magnesium on each side.
Explanation:
The given chemical equation does not hold the law of conservation of mass because the number of atoms of hydrogen and chlorine are not balanced on each side.
Chemical equation:
Mg + HCl → MgCl₂ + H₂
Balanced chemical equation:
Mg + 2HCl → MgCl₂ + H₂
Now this equation hold the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
The number is 33 because 24 + 9 = 33
