Question

When a metal X is treated with a dilute acid Y, then a gas Z is evolved which burns readily by making a little explosion.
a. Name any 2 metals that can behave like metal X.
b. Name any 2 acids that can behave like acid Y.
c. Name the gas Z.
d. Is the reaction between metal X and acid Y exothermic or endothermic?
e. By taking a specific example of metal X and dilute acid Y, write a balanced chemical equation for the reaction which takes place. Also indicate the physical state of all the reactants and the products. ​

Answer 1

Answer:

a sodium pottasium or lithium

Explanation:

it os because in reactivity series they are at the top i.e they react violently with dilute acids

b dil. hcl or dil. h2so4

c hydrogen

d exothermic as heat is released

e 2Na+2HCl =2NaCl +H2
