The balanced chemical reaction will be,
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.
The coefficient tell us about that how many molecules or atoms present in the chemical equation.
When sulfuric acid react with potassium hydroxide then it react to give potassium sulfate and water as a product. This reaction is known as acid-base reaction.
The balanced chemical reaction will be,
Answer:
Follows are the solution to the given question:
Explanation:
Dry Soil weight = solid soil weight =
solid soil volume =
saturated mass soil =
The weight of the soil after drainage is =
Water weight for soil saturation =
Water volume required for soil saturation =
Sample volume of water:
Soil water retained volume = (draining field weight - dry soil weight)
(Its saturated water volume is equal to the volume of voids)
