Answer:
The mass of iron needed to react with the oxygen is 70 g.
Explanation:
The balanced chemical reaction between iron and oxygen is given as;
4Fe + 3O₂ ----------> 2Fe₂O₃
Molecular mass of 3O₂: 3(16 x 2) = 96 g
Molecular mass of 4Fe: 4(56) = 224 g
96 g of O₂ ---requires--------> 224 g of Fe
30 g of O₂ -------requires--------->? Fe
= (30 x 224) / 96
= 70 g
Therefore, the mass of iron needed to react with the oxygen is 70 g.

Atomic size decreases along a period because of the nuclear charge increasing, this means that the electrons are more attracted to the nucleus, which decreases the size.
Atomic size increases down a group because the number of electron shells is greater each time, meaning that the electrons are less attracted to the nucleus.
Moles of Sulfuric acid- H₂SO₄ needed to react completely : 3.2 moles
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction(balanced)
<em>2LiOH + H₂SO₄ → Li₂SO₄ + 2H₂O</em>
From the reaction equation above, the reaction coefficient shows the mole ratio of reagents and products
moles of Lithium hydroxide-LiOH = 6.4 moles
mol ratio of LiOH : H₂SO₄ = 2 : 1, so mol H₂SO₄ :
