Acompound is tested by dipping a wire loop in a solution of the compound and holding it at the edge of a bunsen flame. what name is given to this type of test

Flame test

Explanation:

There are many tests are present to identify the ions. It is very important before going to perform any test you must know all the information bout it.

Flame test:

The metals ions can be detected through the flame test. Different ions gives different colors when heated on flame. Tom perform the flame test following steps should follow:

Colors produce by ions of some metals:

calcium (Ca+2)    orange-red

lithium (Li+)         red

potassium (K+)   Lilac

copper ( Cu+2)    blue-green

sodium (Na+)       yellow

answer is a

explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
