Answer:
Ag⁺(aq) + I⁻(aq) → AgI(s)
Explanation:
Net ionic equation is a way to write a chemical equation in which you are listing only the species that are participating in the reaction.
In the reaction:
AgNO₃(aq) + NaI(aq) → AgI(s) + NaNO₃(aq).
The ionic equation is:
Ag⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + I⁻(aq) → AgI(s) + Na⁺(aq) + NO₃⁻(aq).
Now, listing only the species that are participating in the reaction:
<h3>Ag⁺(aq) + I⁻(aq) → AgI(s)</h3>
"The other halogens are not as electronegative and so other hydrogen halides cannot form hydrogen bonds between molecules. Only London Forces are formed. - Therefore more energy is required to break the intermolecular forces in HF than the other hydrogen halides and so it has a higher boiling point."

Answer: OH−.
Explanation: Hydroxide, any chemical compound containing one or more groups, each comprising one atom each of oxygen and hydrogen bonded together and functioning as the negatively charged ion OH-.
Answer:
Final temperature of the gas is 576 
.
Explanation:
As the amount of gas and pressure of the gas remains constant therefore in accordance with Charles's law:
where 
and 
are volume of gas at 
and 
temperature (in kelvin scale) respectively.
Here 
, 
and 
So 
849 K = (849-273) = 576
So final temperature of the gas is 576 .
