Answer:
No
Explanation:
A mixture is when two or more substances combine physically together. However, in water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone. ... Therefore, water is not a mixture
The empirical formula : Fe₂O₃
<h3>Further explanation</h3>
Given
34.97g of Iron
15.03g of Oxygen
Required
The empirical formula
Solution
Mol ratio :
Fe(Iron) : 34.97 g : 56 g/mol = 0.624
O(Oxygen) : 15.03 g : 16 g/mol = 0.939
Divide by 0.624 :
Fe : O = 1 : 1.5
Fe : O = 2 : 3
Answer:
2 electrons from magnesium (Mg) is transferred to oxygen (O2) to form Mg2+ and O2-
which combines by strong electrostatic force to form MgO
the equation is
2Mg + O2 -> 2MgO
