The answer is:
It will float
Answer:
1)
Explanation:
the answer to you question Is 1)
Answer:
A) The mass would be the same.
Explanation:
Since there is no loss of any particle to vapor during the phase change process from solid to liquid, the mass of the before and after the process will remain the same.
- In this way, the law of conservation of mass is obeyed.
- Mass is the amount of matter contained in a substance.
- Since there is no room for escape or matter loss, the mass will remain the same.
<h2>Al (s) + O₂ (g)----> Al₂O₃(s)</h2>
Explanation:
Chemical reaction
When two or more substances react and form some new substance it is called as chemical reaction .
For example :
Al (s) + O₂ (g)----> Al₂O₃(s)
Chemical equation
It is the representation of chemical reaction in terms of symbols ,molecular formulas ,moles , states etc .
As we know all chemical reaction obeys law of chemical combination therefore chemical reaction need to be balanced .
Law of conservation of mass
Mass can neither be created nor be destroyed in a chemical reaction , it is always conserved .That is why reactions need to be balanced .
Let us balance
Al (s) + O₂ (g)----> Al₂O₃(s)
After balancing , it becomes :
2Al (s) + 3/2O₂ (g)----> Al₂O₃(s)
