<h3>Answer:</h3>

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)

<h3>Explanation:</h3>

We need to know:

<h3>What are decomposition reactions?</h3>
  • Decomposition reactions are type of reactions in which a compound is broken down into two or more products.
  • When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
  • When this happens the soluble compound such as ionic compounds ionizes to form ions.
  • This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
  • For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.
  • That is;

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)

What is the mass of a titanium alloy that has a heat of fusion of 422.5 joules/gram and requires 2,960 joules of energy to melt
romanna [79]

Answer:- Mass of the titanium alloy is 7.01 g, choice C is correct.

Solution:- The heat of fusion is given as 422.5 joules per gram and it also says that 2960 joules of heat is required to melt the metal completely.

The suggested equation is, Q=mH_f

where Q is the heat energy, m is the mass and Hf is the heat of fusion.

Since, we are asked to calculate the mass, the equation could be written as:

m=\frac{Q}{H_f}

Let's plug in the values in it:

m=\frac{2960J}{\frac{422.5J}{g}}

m = 7.01 g

So, the mass of the titanium alloy is 7.01 g, choice C is correct.
