Consider the ions of potassium (K) and sulfur (S), Write chemical formulas for all possible ionic compounds involving these ions
2 answers:
The compounds between the ions and
are
An ionic compound is a compound that is composed of ions. Let us note that ionic compounds are always such that the sum of the charges on the ions is zero.
You need two potassium atoms to form an ionic bond with one sulfur atom. Potassium ions are formed by donating and losing their electrons in the outermost shell, the lost electrons are gained by sulphur atom to form and
, respectively.
The attraction between the positive ions and negative ions gives rise to the ionic bond and the molecular formula is

Answer : The final temperature of the mixture is,
Explanation :
First we have to calculate the mass of ethanol and water.
and,
Now we have to calculate the final temperature of the mixture.
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of ethanol =
= specific heat of water =
= mass of ethanol = 35.5 g
= mass of water = 45.0 g
= final temperature of mixture = ?
= initial temperature of ethanol =
= initial temperature of water =
Now put all the given values in the above formula, we get:
Therefore, the final temperature of the mixture is,
