Question

write the general reactions and examples of acids with 1. metal 2. metal carbonate and write the general reactions and examples of acids with 1. metal 2. metal carbonate and bicarbonate 3. bases​

Answer 1

Explanation:

Acid+Metal = Salt + hydrogen

HCl+Zn = Zncl2 + H2

Acid+metal carbonate = salt + carbondioxide + water

HCl + Na2CO3 = NaCl + CO2 + H2O

Acid + Metal bicarbonate = Salt + Water + carbondioxide

HCl + NaHCO3 = NaCl + CO2 + H2O

Acid + Base = Salt + Water

HCl + NaOH = NaCl + H2O

Answer 2

Explanation:

Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of force. By resolving force →F into two components : (i) F cosθ in the direction of displacement of the body. (ii) F sinθ in the perpendicular direction of displacement of the body.
