Answer:

Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)

Explanation:

The net reaction is Z n ( s ) + 2 H + ( a q ) → Z n 2 + ( a q ) + H 2 ( g ) The C l − ions are spectators - they don't change.

If Oxygen were to gain 2 electrons, the new electron configuration for the oxide ion
Naddika [18.5K]
It would be most similar to neon. it wouldn’t be sulfur because that’s in the same group as oxygen and has the same number of electrons. and carbon has less than that so the only one that makes sense is neon

1. __ Fe +_ Cl → __FeCl3
Temka [501]

Answer:

2Fe + 3Cl2 → 2FeCl3

Explanation:

Fe + Cl2 —> FeCl3

There are 3atoms of Cl on the right side and 2 atoms on the left side. Therefore, to balance Cl put 2 in front of FeCl3 and put 3 in front of Cl2 as shown below:

Fe + 3Cl2 → 2FeCl3

Now, we see clearly that there are 2 atoms of Fe on the right side and 1 on the left side. This can be balanced by putting 2 in front of Fe as shown below:

2Fe + 3Cl2 → 2FeCl3

Now the equation is balanced.

If someone takes a material that looks pure, and then they do something to it that results
Sati [7]

Answer:

The determination of the nature of the combination of the two separate materials in the original material that looks pure is based on the characteristic of the change process they undergo to become two separate materials.

Therefore, they can know if they initially had a mixture or a compound by the following steps;

1) If the two separated materials can be easily remixed to form the original material, then they likely have a mixture of the two separate materials

2) If the process that results in the formation of the two separate materials, involves the absorption or evolves heat or other forms of energy, then the original substance was a compound

3) If the two newly formed materials is seen to be a permanent change, then the original material was a compound
