Therefore option c , i.e. The substances in both test tubes are reactive only at high temperatures. is the only statement which is NOT supported by the student's observations.
<h3>What is the reaction between Magnesium and Hydrogen ?</h3>
Magnesium reacts with hydrochloric acid to produce hydrogen gas
Mg (s) + 2 HCl (aq) → MgCl₂ (aq) + H₂ (g)
In this reaction, the magnesium and acid are gradually used up , which can be seen in the test tube 2 .
A chemical reaction is taking place in Test tube 2 ,
Hydrogen gas is released in test tube 2 ,
Energy is released in the reaction involving hydrochloric acid and we can see in test tube 2 the reaction is going on
therefore option C i.e. The substances in both test tubes are reactive only at high temperatures. is the only statement which is NOT supported by the student's observation.

Answer:
<h3>In chemical reaction atoms are reactants </h3>
Herd behavior in elephants ensures that individuals are protected and the species is perpetuated.
<h3>What is her behavior?</h3>
It is a behavior that is characteristic of animals that form herds.
Herds generally refer to groups of animals that live or move together or both.
By protecting individual elephants that are weak or young from being preyed upon by lions and leopards, more members of the population survive.
When more members of the population survive, the species is perpetuated and the likelihood of going into extinction reduces.

A measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. The temperature of a substance is closely related to the average kinetic energy of its molecules.
