8Fe + 6O₂ -----> 4Fe₂O₃
If eight atoms of iron react completely with six molecules of oxygen, 4 molecules of iron (III) oxide will be formed.
They can form acids or ‘acid rain’ like nitric acid or sulfuric acid which can damage buildings and structures.
Atoms of the same element will always contain the same number of protons
<h3>
Answer:</h3>
The conservation of mass and matter is true
<h3>
Explanation:</h3>
- The law of conservation of mass requires that the mass of reactants and products be equal in chemical reactions.
Given the equation;
AgNO₃ + HCI → AgCI + HNO₃
- The equation is balanced because, it has 1 silver atom, 1 nitrogen, 3 oxygen atoms, 1 hydrogen atom, and 1 chloride atom on both side of the equation.
- Therefore, the mass of the reactants and the products is equal which makes the law of conservation of mass hold.
- The conservation of matter is also true since the reaction process without changing the number of atoms of each element.
The angle of incoming sunlight varies at different places.
