There are three number of electrons lost by 1 mole of aluminium because aluminum has +3 charge on it.
<h3>What is cation?</h3>
When an atom loses electron, positive charge appears on the atom this is called cation. In this reaction we can see that aluminium has +3 charge which means that it loses 3 electrons.
So we can conclude that There are three number of electrons lost by 1 mole of aluminium because aluminum has +3 charge on it.

Answer:
Limiting reactant: Oxygen 
Explanation:
First write the balanced chemical equation:
given mass of methane =25g
molecular mass of methane=16g/mol
mole=1.5625mol
given mass of oxygen=50
molar mass of oxygen=32g/mol
mole=1.5625mol
from the above balanced equation it is clearly that,
1 mole of methane needs 2 moles of oxygen for complete reaction
Therefore,
1.5625 moles of methane needs 3.125 moles of oxygen for complete reaction but we have only 1.5625 moles of oxygen,
hence,
oxygen will be the limiting reactant and methane will be the excess reactant
Answer:
The difference is the combining vowel
Explanation:
The Combining form needs the vowel to form, that is:
root word + combining vowel = combining form
<u>Root word</u>:
A root is a word that does not have a prefix in front of the word or a suffix at the end of the word. The root word is the main lexical unit of a word and a family of words, which carries the most significant aspects of semantic content and cannot be reduced to smaller components
<u>Combining form</u>:
Training process of words from two or more roots or simple words.
When the word includes a cultured base and a patrimonial base, we will consider derived word. For example, hypermarket, bi-monthly
