<h3>
Answer:</h3>
The equation is balanced since the number of atoms of each element are equal on both side of the equation.
<h3>
Explanation:</h3>
- Balancing chemical equations involves putting coefficient on the reactants and products of a chemical reaction.
- It results to equal number of atoms of each element on either side of the equation.
- A balanced chemical equation obeys the law of conservation of mass such that the mass of reactants is equal to the mass of products.
- The equation; 4AI(s) + 3O₂(g) → 2AI₂O₃(s) is balanced since the number of atoms of each element are equal on both side of the equation.
- That is, 4 aluminium atoms and 6 oxygen atoms on both side of the equation.
They are found in group 3 of the periodic table.
Answer:
4
Explanation:
The zeros before a non zero digit do not count as significant figures so there are 4 sig figs in the number
With the current energy shortage, nuclear energy can be seen as a more practicle option
Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
