The following balanced equation shows the decomposition of water (H2O). According to the equation, how many oxygen atoms are in
2 answers:
Answer : The number of oxygen atoms present on reactant side are, 4
Explanation :
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
Decomposition reaction : It is defined as the reaction in which the larger molecule decomposes to give two or more smaller molecules as a product.
The given balanced chemical reaction is,
From the balanced chemical reaction we conclude that, there 4 atoms of hydrogen and 2 atoms of oxygen present on both reactant side and product side.
Hence, the number of oxygen atoms present on reactant side are, 4

<u>Answer:</u> When bleach is mixed with water, it produces hypochlorous acid.
<u>Explanation:</u>
The chemical name for bleach is sodium hypochlorite. When this compound is reacted with water, it produces hypochlorous acid and sodium hydroxide.
The chemical equation for the reaction of sodium hypochlorite and water follows:
By Stoichiometry of the reaction:
1 mole of sodium hypochlorite reacts with 1 mole of water to produce 1 mole of hypochlorous acid and 1 mole of sodium hydroxide.
Hence, when bleach is mixed with water, it produces hypochlorous acid.
The alcohol concentration of the mixed solution is 20%
Simplification :
Based on the given condition, formulate :
35% ×0.40 + 0.6 ×10% ÷{ 0.4+0.6}
Calculate the product :
Calculate the sum or difference :
Any fraction with denominator 1 is equal to numerator : 0.2
Multiply a number to both numerator, denominator : 0.2 ×
Calculate the product or quotient :
A fraction with denominator equals to 100 to a percentage 20%.
How do you find the concentration of a mixed solution?
In general when your are mixing two different concentrations together first calculate number of moles for each solution (n=CV ,V-in liter) then add them together it will be total moles,then concentration of mixture will be = total moles / total volume(liter).
