<span>1)false a in chemical equilibrium concentration of reactant is equal to concentration of product
2)as here they said heat is added in product side means its endothermic reaction and in endothermic reaction on increasing temp. equilibrium shift towards forward direction so its true
3) B)as here mole are equal in reactant and product side that is 2 and if we increase pressure equilibrium shift in dat direction where no. of moles are less and here mole are equal so it will remain unaffected</span>

Nickel is the 28th chemical in the periodic table and the chemical symbol of copper (II) nitrate is Cu(NO₃)₂. The chemical reaction that occurs between these compounds is a single-replacement reaction.
From the activity series of metals, nickel is able to replace copper in the compound and this is expressed in the balanced equation,
Ni(s) + Cu(NO₃)₂(aq) --> Cu(s) + Ni(NO₃)₂(aq)
The phases are also written in the equation.
