<span>There are two atoms of sodium and one atom of oxygen. lmk if its right or wrong</span>
Answer:
1) S2N
2)ClI
Explanation:
A chemical formula shows the relative ratio of atoms present in a compound. When we write a chemical formula, we have an idea of the ratio in which atoms combine in the compound of interest. This is a great clue when we are attempting to elucidate the structure of the compound.
For hexasulphur mononitride,the formula of the compound must be S6N3, this reduced to lowest terms to give S2N.
Similarly, the formula for chlorine monoiodide is ClI as shown in the answer above.

Answer : The final temperature of the solution in the calorimeter is,
Explanation :
First we have to calculate the heat produced.
where,
= enthalpy change = 82.8 kJ/mol
q = heat released = ?
m = mass of = 5.10 g
Molar mass of = 110.98 g/mol
Now put all the given values in the above formula, we get:
Now we have to calculate the final temperature of solution in the calorimeter.
where,
q = heat produced = 3.80 kJ = 3800 J
m = mass of solution = 100 + 5.10 = 105.10 g
c = specific heat capacity of water =
= initial temperature =
= final temperature = ?
Now put all the given values in the above formula, we get:
Thus, the final temperature of the solution in the calorimeter is,
D. this is the correct answer because the question is showing a comparison of sizes rather than the actual sizes which eliminates B. A and C have no relevance.
