Answer:
A). CH4.
Explanation:
Ar and Mg are elements.
LiBr and NaI are ionic compounds.
CH4 has 4 covalent bonds between the carbon and hydrogen atoms.
The answer would be A: THE PRESSURE IN THE EYE IS INCREASING.
HOPE THIS HELPS :)
Answer: ![2NaNO_3(aq)+(CH_3COO)_2Pb(aq)\rightarrow 2CH_3COONa(aq)+Pb(NO_3)_2(aq)](https://tex.z-dn.net/?f=2NaNO_3%28aq%29%2B%28CH_3COO%29_2Pb%28aq%29%5Crightarrow%202CH_3COONa%28aq%29%2BPb%28NO_3%29_2%28aq%29)
Explanation: A double displacement reaction is one in which exchange of ions take place.
The compounds which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
Thus the exchange of ions take place and all the compounds are soluble so the chemical formulas are followed by the symbol (aq).

See explanation below
Explanation:
You are not providing the starting material, however, I manage to find a similar question to this, so I'm gonna use it as a basis to help you answer yours.
Now let's analyze what is happening in the reaction so we can predict the final product.
We have a ketone here, reacting at first with LDA. This is a very strong base that is commonly used in reactions with ketones and aldehydes to promove a condensation. To do this, as LDA is a strong base it will occur firts an acid base reaction, substracting the most acidic hydrogen in the molecule (Which in this case, is the Beta hydrogen of the carbonile). This will cause an enolate formation.
Then, this enolate will react with the CH3I and form a new product. The final result would be a ketone with a methyl group now attached. In the picture 2, you have the mechanism and final product.
Hope this helps
