Question

I need help asap it is past due pls give the definition of the following

Answer 1

Reactivity: the state or power of being reactive or the degree to which a thing is reactive.

Tarnishing:  lose or cause to lose luster, especially as a result of exposure to air or moisture.

Endothermic:  (of a reaction or process) accompanied by or requiring the absorption of heat.

(of a compound) requiring a net input of heat for its formation from its constituent elements.

Rusting: deteriorate through neglect or lack of use.

Exothermic: (of a reaction or process) accompanied by the release of heat.

(of a compound) formed from its constituent elements with a net release of heat.

Hope this helps!

Answer 2

Answer:

reactivity-In chemistry, reactivity is the impetus for which a chemical substance undergoes a chemical reaction, either by itself or with other materials, with an overall release of energy.

Tarnishing- is a thin layer of corrosion that forms over copper, brass, aluminum, magnesium, neodymium and other similar metals as their outermost layer undergoes a chemical reaction. Tarnish does not always result from the sole effects of oxygen in the air.

endothermic -(of a reaction or process) accompanied by or requiring the absorption of heat.

(of a compound) requiring a net input of heat for its formation from its constituent elements.

Rusting-deteriorate through neglect or lack of use.

exothermic-of a reaction or process) accompanied by the release of heat.

(of a compound) formed from its constituent elements with a net release of heat.
