Answer:
The reason why Newtons first law of motion is sometimes called the law of inertia is because it states that if the object is in motion, it will not rest unless an unbalanced force acts on the object.
Answer:
1 mole of Al³+
Explanation:
Balanced chemical equation;
Al³⁺ + Na₃PO₄ → 3Na⁺ + AlPO₄
From the above chemical equation, it is evident that this is displacement reaction which is a reaction involving one atom or charge displacing another one in the chemical reaction.
In this reaction, Al³⁺ has a charge of +3 while Na⁺ has a charge of +1. When Al³⁺ displaces Na⁺, it meets an anion of PO₄³⁻ and since both charges are equal, i.e +3 and -3, there's is a mutual exchange of electrons and bond formation occurs.
The ratio of AlPO₄ to Al³⁺ is 1 : 1
I.e 1 mole of Al³⁺ produce 1 mole of AlPO₄

correct me if i’m wrong
- No of protons=No of electrons=15
<h3>Mass no:-No of neutrons+No of protons </h3>
Now
