How many C atoms are there in 5.25 grams of a compound containing 92.26% C and 7.74% H?
Damm [24]
Take 5.25 grams and give it proportionally to the carbon
0.9226 * 5.25 grams = 4.84 grams Carbon
Find the number of moles
(4.84 grams carbon)/(12.01 grams/mol) = 0.403 moles Carbon
The number of atoms in a mole of a substance is called Avogadro's number.
There are 6.022 * 10^23 atoms in one mole of anything
(0.403 moles Carbon) * (6.022 * 10^23 atoms/mole) = 2.43 * 10^23 atoms of Carbon

ohaa [14]

Answer:

Explanation:

Similarities.

Both Ionic and covalents bond produce exothermic reactions.

They are both neutral.in Ionic bonds, the two opposite charge will terminate each other and in covalent, the neutral molecules tend to share electrons.

Difference

Ionic bonds have high polarity while covalent have low.

Ionic bonds have no definite shape, covalent have.

Ionic have high melting points, covalent have low.

Io ic have high boiling point, covalents have low.
