Consider the reaction 2AI(OH)3 + 3H2SO4 Right arrow. X + 6Y. What are X and Y? X = AI2(SO4)3; Y = H2O X = AI2(SO4)3; Y = H2 X = AI2(SO3)3; Y = H2O X = AI2(SO3)3; Y = H2

Answer :

X =

Y =

Explanation :

Balanced chemical equation : It is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The given chemical equation is:

As we know that when aluminum hydroxide react with sulfuric acid then it gives aluminum sulfate and water as product.

The balanced chemical reaction will be:

Thus, X is and Y is

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

a) the particles of the chair are strongly held together.
