The formula unit equation for the given reaction occurring in water is
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).
<h3>What is chemical reaction?</h3>
Chemical reactions are those reaction in which reactant molecules react with each other for the formation of product.
When calcium sulfide reacts with iron (II) bromide for the formation of iron(II) sulfide and calcium bromide will be represented through the following equation:
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq)
Above reaction best explains the formula unit of given reaction as all valency of atoms are satisfied there.
Hence, the required formula unit is CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

Answer:
Yes. There must be a difference.
Explanation:
The part of water with low density (warm or hot) would rise, and the cold water would sink. This creates a convection.
From what I remember, the moon has little to no atmosphere, this means that if an asteroid came hurling towards it, there would be nothing between it and the asteroid, so it would just come crashing down to the moon. Whereas the Earth has a much thicker atmosphere than the moon and if a asteroid came hurling towards the Earth, it would most likely burn up or break apart in the atmosphere before it reached the earths surface.
I hope this helped! :-)
Answer:
67° C increase
Explanation:
235 gm * 4.186 J /g-C * x = 66 000 J x = degree change C°
x = 67 degrees C
