Addition of 6 m hcl to which substance will not result in gas evolution? (a)al b)zn c) k2co3 (d) nano3

Addition of 6 M HCl to NaNO₃ will not result in gas evolution

HCl is a strong acid that is fully ionized in water

There are several reactions that involve reactions with HCl

Aluminum is a metal element in the third period

Aluminum will react with acids such as HCl to produce hydrogen gas

Reactions that occur:

Al (s) + 3H + (aq) ⇒ Al³⁺ + 3/2H₂ (g)

Zinc is a transition metal element

Zn reaction with HCl will produce hydrogen gas

Zn + HCl ⇒  ZnCl₂ + H₂

Potassium carbonate is a salt produced from the reaction of potassium hydroxide with carbon dio/xide

HCl reaction with K₂CO₃

HCl + K₂CO₃ ⇒ H₂CO₃ + KCl

H₂CO₃ is a weak acid, will decompose into CO₂ and H₂O

H₂CO₃ ⇒ CO₂ + H₂O

So this reaction producing CO₂ gas

Sodium nitrate is a salt

Reaction with HCl

HCl + NaNO₃ -> NaCl + HNO₃

produces no gas , NaCl salt and strong acid HNO₃

Periodic element

put the answers   and i could answer.

i don,t know so just answer mine
