Answer:
Gas liquid solid
Explanation:
gases have a weak potential since they have a weak bond between molecules while in solids it's the strongest making them vibrate in a fixed position

<u>Answer:</u> The balanced half reaction is written below.
<u>Explanation:</u>
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
When oxygen gas is reduced to oxide ions, the number of electron transferred are 2
The chemical equation for the reduction of oxygen gas to oxide ions follows:
Hence, the balanced half reaction is written above.
Answer:
The ionic bond present between CaO molecule
Explanation:
Answer:
4 : 3
Explanation:
The balanced chemical equation is given as follows:
2Al₂O₃ ..............> 4Al + 3O₂
Now, from this equation we can note that:
For every 4 moles of aluminum moles produced, corresponding 3 oxygen moles are produced.
This means that the ratio between the formation of aluminum to the formation of oxygen moles is 4:3
Hope this helps :)
