Hydrochloric is added to a beaker containing a piece of zinc. as a result, zinc chloride is formed and hydrogen gas is released. this is an example of a evaporation b photosynthesis c a physical change d a chemical reaction

D. A chemical reaction

Explanation:

The evolution of a gas and the formation of a new solid with different properties are signs that the original materials have changed into something else.

They have been in a chemical reaction.

A is wrong. Evaporation is a physical change in which the molecules of the liquid move into the gas phase.

B is wrong. Photosynthesis is the use of sunlight by a plant to convert carbon dioxide and water into glucose.

C is wrong. A physical change does not involve a change to another substance with new chemical properties.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
