Answer:
The answer to your question is: 24 grams of D
Explanation:
To answer this question we need to remember the Lavoisier law of conservation of mass, which says that in a chemical reaction matter is neither created nor destroyed.
This means that the amount of matter stays the same.
Then, the reaction is
A + B ⇒ C + D
26 g 12 g 14 g x
mass
of reactants 38 g ? mass of products, but it must be
equal to the mass of products
Then 14g + x = 38
x = 38 - 14
x = 24 g of D
4 grams , mass cannot be created or destroyed. it has to be the same on both sides of the equation
Physical properties can be observed or measured without changing the composition of matter. These are properties such as mass, weight, volume, and density. Remember that density is a physical property.
General principle of solubility is 'like dissolves like'

is an ionic compound, wherein the constituent ions (

and

) are held by electrostatic forces of interaction.
Such ionic compounds are soluble in polar solvents.
Among the solvent mentioned in question, water (

) has maximum polarity. Hence,

is most likely to dissolve in
