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
The freezing point constant means that the temperature depression when adding one mole of the solute. The mole number of the solute is 10.20/180=0.0567 mol. So the answer is 1.86*0.0567=0.105 ℃.
Answer:
<h2>3.31 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 23.2 g
volume = final volume of water - initial volume of water
volume = 62 - 55 = 7 mL
We have

We have the final answer as
<h3>3.31 g/mL</h3>
