Answer:
It can be produced, 12 moles of MgO.
Option B
Explanation:
2 KClO₃ → 3O₂ + 2 KCl
Ratio in this reaction is 2:3
In the begining, I make 3 moles of oxygen, that came from 2moles of chlorate. If I have 4 moles of salt, let's make a rule of three.
2 moles of salt ___ make __3 moles of O₂
4 moles of salt ___ make (4 .3) /2 = 6 moles of O₂
2 Mg + O2 → 2 MgO.
From 1 mol of oxygen, I can make 2 moles of oxygen.
If I have 6 moles, I would make the double, though.
Answer:
Here's what I get
Explanation:
Both diamond and SiO₂ are network solids. Their atoms are all joined together so a crystal of either diamond or SO₂is one giant molecule.
Structure
In diamond, each C atom is covalently attached to four other C atoms.
The structure of SiO₂ is like that of diamond. The difference is that there is an O atom between each atom of Si.
Properties
Both substances are
- High-melting
- Hard
- Insoluble in both polar and nonpolar solvents
- Poor conductors of electricity
