(1) O2 Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(2) Xe Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(3) C3H8 Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(4) KNO3 Is an electrolyte: because it ionizes when dissolved in a solution
Electrolytes:
Electrolytes are the substance whose aqueous solution conducts electricity. These are mainly two types:
1. Strong electrolytes
2. Weak electrolytes:
Strong electrolytes:
Strong electrolytes have following properties:
1. They are ionic compounds.
2. They are completely separates into their ions when dissolved in water.
3. In solution form they conduct electricity due to present of ions but in solid form means neutral molecule does not conduct electricity.
Weak electrolytes:
Weak electrolytes are partially ionizes in water.
In general strong electrolytes are strong acid and strong base while weak electrolytes are weak acid and weak bases.
Nonelectrolyte:
The substance which does not ionize when dissolved in a solution is called non-electrolyte. It is a poor conductor of electricity.
Since f is positive I would say f
Answer:
The right choice is CHCl₃
Explanation:
- <u>To find the empirical formula firstly, change the mass to moles.</u>
For Carbon :
no. of moles = (mass / molar mass) = (5.03 g / 12 g/mol )= 0.42 mol
<u><em>For Hydrogen :</em></u>
no. of moles = (mass / molar mass) = (0.42 g / 1 g/mol )= 0.42 mol
<u><em>For Chlorine :</em></u>
no. of moles = (mass / molar mass) = (44.5 g / 35.5 g/mol )= 1.25 mol
The ratio for Carbon and Hydrogen is 1 : 1
0.42 mol / 042 mol =1.00
- <u>
Then find a ratio between the moles.
</u>
The ratio of Chlorine to both Carbon and Hydrogen is 3:1
1.25 mol / 0.42 mol = 2.98 ≅ 3
So the ratio is 1 C : 1 H : 3 Cl.
So, the right choice is CHCl₃
Carbon usually forms four bonds one to Hydrogen and 3 to Chlorine atoms.
Chlorine usually forms one bond to Carbon atom.
Hydrogen usually forms one bond Carbon atom.
