Give an example of a chemical reaction in chemical equilibrium. Define chemical equilibrium using your chemical equation.
Chemical equilibrium in which concentration of reactant and concentration of products is constant and it's do not change with respect to time.Example is that water flow from a tap

Using a suitable chemical equation define HCl as a Bronsted Lowry Acid
HCl(aq) + H2O (l) → H3O+(aq) +Cl−(aq) Using the Brønsted-Lowry theory, the reaction of ammonia and hydrochloric acid in water is represented by the following equation: NH3(aq) + HCl(aq) →...

In the following equation, label the Bronsted-Lowry acid, base and conjugate pairs. (2 marks) CH3NH2 (aq) + H2PO4- (aq) ↔ CH3NH3+ (aq) + pOH HPO42- (aq)
CH3NH2 (aq) + H2PO4- (aq) ↔ CH3NH3+ (aq) + HPO42- (aq)Here, CH3NH2 accepts a proton while H2PO4- donates this proton. From here, conjugate pairs are:H2PO4- - acid, HPO42- - conjugate baseCH3NH2 - base, CH3NH3+ - conjugate acid

Balanced equations for the following does reaction occur thank you
Fe + HCl
Cu + HCl
Zn + HCl
Fe + HNO3
Cu + HNO3
Zn + HNO3
Fe(s) + 2HCl(aq) → FeCl2(aq) + H2(g) – reaction occurs Cu(s) + 2HCl(g) → CuCl2(s) + H2(g) – reaction occurs at 600 Celcius Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)...
