Question

3. Some apparatus and chemicals are given.
(Zn, Mg, DiaHCl, CaCO3 , test tube, water.)
a) Design an experiment to prove that the nature of reactants can
influence the rate of reaction.
b) Write the equations for the chemical reactions.
c)Write the procedure and result of the above mentioned reaction

Answer 1

Answer:

double displacement IS THE answer for ur question mark me brainlist and follow me

Answer 2

Answer:

Explanation:

(a) Take a volume of dil HCl in two test tubes. Add a piece of Mg m to one of them . Add a piece of Zn of equal mass to the other.

Observation : Mg reacts faster with dil. HCl than Zn. This is due to the difference in the chemical nature of Mg and Zn.

(b) Mg+2HCl→MgCl2+H2

ZN+2HCl => ZNCl2+H2

(c) rate of chemical reaction

=>amount of reactant used up/Time

=>amount of product formed/time
