state reactants and products
what type of heat change is observed in this reaction?
write word equation for this reaction?
write chemical equation for this reaction? ​

Answer 1

Answer:

Please mark as brainlist

Explanation:

The metal zinc readily reacts with hydrochloric acid to produce hydrogen gas (H2) and zinc chloride (ZnCl2). Every chemical reaction either produces or absorbs heat. In chemistry this effect is described as the reaction enthalpy. The zinc reaction produces the heat and hence has the negative enthalpy.

Answer 2

REACTANTS: ZINC AND HYDROCHLORIC ACID

PRODUCTS: ZINC CHLORIDE AND HYDROGEN GAS

WORD EQUATION:

ZINC + HYDROCHLORIC ACID = ZINC CHLORIDE + HYDROGEN GAS

CHEMICAL EQUATION:

Zn+HCl= ZnCl2 + H2
