Well, which one of the choices is different? Freezing, solidifying, and condensing mean that the substance is getting colder. With melting, heat is being added to the substance meaning it is changing to a less condensed state of matter. The answer is melting.
Elements are pure substances made up of molecules
Balanced chemical equation for the given reaction is Fe₂(CO₃)₃ + 6Cs → 3Cs₂CO₃ + 2Fe.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equations in which all entities are present in equal amount on reactant side as well as on product side.
Given balanced chemical reaction is:
Fe₂(CO₃)₃ + 6Cs → 3Cs₂CO₃ + 2Fe
Above given equation is a balanced chemical equation where all atoms of reactant as well as of products are present in same amount.
Hence, required balanced equation is Fe₂(CO₃)₃ + 6Cs → 3Cs₂CO₃ + 2Fe.

His group's cube was made of <span>D) zinc. Looking up the density values of each of the choices, it can be seen that zinc has the closest density out of all of them. It's actual density has a value of 7.14 g/cm3. The others have density values that are way too far from the average density of 7.4 g/cm3.</span>
Answer:
Acetamide
Explanation:
The reaction can be expressed as:
CH₃COOH + NH₃ → CH₃CONH₂ + H₂O
It's worth mentioning that this reaction would have a better yield if we use an appropiate catalyst such as DCC, in order to prevent an acid-base reaction and instead have the previous <em>amidation</em> reaction.
