A spectator ion is (Select all that apply.) a. an ionic component of a reactant that is unchanged by the reaction your eye, b. c
DENIUS [597]

Correct Question:

A spectator ion is (Select all that apply.)

- a piece of french fry contaminating the reaction mixture

- an ionic component of a reactant that is unchanged by the reaction

-in this experiment, nitrate ion

- your eye, carefully watching the progress of the reaction

Answer:

- an ionic component of a reactant that is unchanged by the reaction

Explanation:

A spectator ion is an ion that exists as a reactant and a product in a chemical equation. A spectator ion is one that exists in the same form on both the reactant and product sides of a chemical reaction.

Spectator ions are ions that are present in a solution but don't take part in the reaction. When reactants dissociate into ions, some of the ions may combine to form a new compound. The other ions don't take part in this chemical reaction and are therefore called spectator ions.

The correct option is therefore the option;

- an ionic component of a reactant that is unchanged by the reaction

We can see water change state, from ice to steam. This is a __________ change in matter. A) chemical B) combustion Eliminate C)
Gemiola [76]

Answer: Option (C) is the correct answer.

Explanation:

When chemical composition of a substance is not changing in a chemical reaction then it is known as a physical change.

For example, when water change state, from ice to steam then it means solid state is changing into gaseous state.

Therefore, it is a physical change.

And, a reaction which causes change in chemical composition is known as a chemical change.

For example, Li + Cl \rightarrow LiCl

Thus, we can conclude that we can see water change state, from ice to steam. This is a physical change in matter.
