Answer:
zince chloride will be formed and hydrogen gas will be librated.
Explanation:
When dilute HCl is added to zinc pieces, a rection will takes place as follows :
It means that zinc chloride will form when zinc reacts with dilute HCL. Also hydrogen gas will produced.
As zinc is more reactive than hydrogen, it displaces hydrogen from its solution and forms zinc chloride. The form product is white in color and H₂ is an odorless gas.
Hence, zince chloride will be formed and hydrogen gas will be librated.
Answer: When the particles lose heat they move more slowly and have a decrease in kinetic energy.
Heat is a <u>form of energy</u> that is manifested by an <u>increase in temperature</u> and comes from the transformation of other energies. <u>Heat is caused by the vibratory movements of atoms and molecules that make up bodies or substances</u>. Specifically, for physics, heat is a type of energy that is transferred from one system to another, a transfer that is linked to the <u>disordered movement of molecules, atoms and other particles</u>. In this way, when losing heat, the particles lose energy in the form of kinetic energy, so they begin to vibrate and move slower.
