<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Double displacement reaction is defined as the reaction in which exchange of ions takes place.
The chemical equation for the reaction of hydrochloric acid and potassium sulfide follows:
By Stoichiometry of the reaction:
2 moles of hydrochloric acid reacts with 1 mole of potassium sulfide to produce 2 moles of potassium chloride and 1 mole of hydrogen sulfide gas
Hence, the balanced chemical equation is written above.
The atmosphere is a mixture of gasses.

Eleanor wants to show her class a comparison of melting
rates between two different solids when heat is applied. A graph would be more
suitable than a table to show her data because the she can see the trend line
of the effects of melting than the table.
