Answer:
The balanced equation is: H2 (g) +Cl2 (g) →2HCl (g)
Explanation:
Balancing chemical equation refers to balancing the stoichiometric coefficients on the reactants and products side. This must be done as the chemical equation obeys the law of conservation of mass and momentum.
The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. The Law of conservation of mass governs the balancing of a chemical equation.
Given chemical equation
The balanced chemical equation for the hydrogen + chlorine -> Hydrogen Chloride.
H2 + Cl2 → 2HCl
The equation is balanced as on the reactants side there are two hydrogens present and the same on the products side. For chlorine as well the same thing goes two chlorine atoms on the reactants side and two on the products side.
Answer:
13.0mL
Explanation:
So this is a classic M1V1=M2V2 problem, where M is molarity and V is volume and the subsequent numbers represent the two sets of condition (1 being before dilution and 2 being after dilution)
So M1 is going to be 5.0M because it is our initial molarity and V1 is what we are trying to find since we are trying to find how much of initial volume should be diluted.
M2 is 1.30M since it is what molarity is after dilution and M2 is what volume is after dilution which is 50mL.
So M1V1=M2V2 (becomes an algebra problem)
5*V1=1.30*50
V1= 13.0mL
Now this answer should make sense since to dilute something with large molarity to small you only need very few mL than the final volume because you add water to dilute it.
