2 answers:
Answer: Option (d) is the correct answer.
Explanation:
The given formula has three sulfur atoms and two chlorine atoms.
is a covalent compound as it is formed by sharing of electrons.
So, according to the nomenclature rule "tri" will be added before the name of cation because there are three atoms of cation and "di" will be added before the name of anion.
Therefore, we can conclude that the correct name of compound is Trisulfur dichlroide.

ANSWER
EXPLANATION
Given that
The energy released by the system is 12.4J
Work done on the surrounding is 4.2J
Follow the steps below to find the change in energy
In the given data, energy is said to be released to the surroundings
Recall, that exothermic reaction is a type of reaction in which heat is released to the surroundings. Hence, change in enthalpy is negative
Step 1; Write the formula for calculating change in energy
Since heat is released to the surrounding, then q = -12J
Recall, that work done by the system on the surroundings is always negative
Hence, w = -4.2J
Step 2; Substitute the given data into the formula in step 1
Therefore, the change i
