Lets name the unknown metal as M. Cation would be M³⁺.
the molecular formula of the compound is M₂(SO₄)₃
the mass of one mole - (molar mass of M x2 + 3 x molar mass of SO₄²⁻)
= 2M + 96 x 3
= 2M + 288
In 1 mol if there's 72.07% of sulphate ,
then 72.07 % corresponds to 288 g
1 % is then - 288/72.07
100 % of the compound - 288/72.07 x 100
molar mass of the compound - 399.6 g/mol
mass of 2M - 399.6 - 288 = 111.6 g
molar mass of M - 111.6 /2 = 55.8 g/mol
the element with molar mass of 55.8 is Fe.
Unknown metal is iron(III) , Fe³⁺
Answer:
It would react better than what with dilute and will furnish more hydrogen gas.
Invertebrates affect the oxygen levels of compost and soil by reducing it.
<h3>How respiration works?</h3>
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.
Every living organism undergoes the process of cellular respiration and make use of oxygen molecules in the process.
This means that invertebrates will make use of the oxygen gas present in compost and the soil for respiration, hereby reducing it.
