Write a balanced equation for the formation from its elements of sodium peroxide, an industrial bleach.
1 answer:
The answer is- The balanced equation is →
.
A balanced chemical equation is the one in which there is same number of each types of atoms on both the reactant and product side.
An unbalanced chemical reaction violates which law?
- To balance the equation, we keep the count of the elements balanced on both sides of the reaction which maintains the same total mass of elements on both sides.
- Thus, if an equation is not balanced, then it violates the law of conservation of mass.
- Now, the chemical formula of sodium peroxide (industrial bleach) is
. Thus, its constituent elements are sodium (
) and oxygen (
).
- Therefore, the chemical equation is -
→
- But the above equation is not balanced as the number of
- Hence, the balanced equation is
→

Molarity is the number of moles of solute in one liter of solution whereas molality is the number of moles of solute present in 1 kilo gram of solution.
Molarity is denoted by M and molality denoted by m
Mass of solution
Density of solution = 1.1 g /mL
d = 1.1 = (W_B + W_A) /V
V = 910.11 mL
molarity of solution is:
= 0.0433 /0.910 = 0.0474 M
Thus, moalrity of solution is 0.0474 M
