1) Ions are formed between positive or negative charge.
RSB [31]

Answer:

1. No 1 looks like a statement and not a question.

2.Ionic compounds are usually formed from the transfer of electrons from metals to Non metals. All others are Ionic compounds except HCl(Its a covalent compound).

3. The Formula would be K2S. Exchange of Radicals takes place. Sulphur has a -2 charge and potassium has a +1 charge. when they both exchange radicals... The compound is K2S.

4.Group 1 elements have only 1 electron in their outermost shell.

5. its charge will be +1 because it loses the 1 electron in its outermost shell.

6.Group 2 elements have 2electrons in their Valence shell.

7.Already answered. same as No 5.

8. Group 16;Also known as group 6. They have only 6 electrons in their outermost shell.

9.When they want to become stable... they acquire 2electrons to complete their octet... so they possess a -2 charge by forming an ion.

10. i)They form ions when Dissolve in solutions

ii) They are hard and brittle

iii) They have high boiling points

Nitrous oxide (n2o), or laughing gas, is commonly used as an anesthetic in dentistry and surgery. how many moles are present in
Gelneren [198K]

Answer is: 0.375 moles are present in 8.4 liters of nitrous oxide at stp.

V(N₂O) = 8.4 L.

V(N₂O) = n(N₂O) · Vm.

Vm = 22,4 L/mol.<span>
n</span>(N₂O) = V(N₂O) ÷ Vm.

n(N₂O) = 8.4 L ÷ 22.4 L/mol.

n(N₂O) = 0.375 mol.<span>
Vm - molare volume on STP.</span>
