Answer : The correct option is C.
Explanation :
Enthalpy of reaction : It is defined as the changes in heat energy takes place when reactants go to products. It is denotes as 
.
= Energy of product - Energy of reactant
is positive when heat is absorbed and the reaction is endothermic.
is negative when heat is released and the reaction is exothermic.
In the given potential energy diagram, the energy of product at higher level and energy of reactant at lower level. The for this reaction will be positive.
So, the enthalpy of reaction is defined as the difference of the energy of the reactants and the energy of the products.
Answer:
hi
Explanation:
A mixture which has uniform composition throughout its mass is called homogeneous mixture. The word "homo" means "same". For example, when you completely dissolve salt in the water, you form a homogeneous mixture.
Answer:
they got protons, electrons, and neutrons
Explanation:
Answer:
Explanation:
Aqueous solution of copper sulphate
is acidic in nature, as when copper sulphate on dissolving with water, following chemical reaction takes place :
CuSO4 + 2 H2O ====> Cu(OH)2 + H2 SO4
As we can see, copper hydroxide and sulphuric acid is generated in this chemical reaction.Copper hydroxide is a weak base whereas sulphuric acid is a very strong acid which results into increase in acidity of the solution.
Thus, the aqueous solution of copper sulphate is acidic in nature.
