Balanced chemical equation for the decomposition of solid sodium sulfide in aqueous solution.
Oliga [24]
<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)

If you added 45,000 calories to water that was at 25 degrees C, and the ending temperature was 35 degrees C, how much water did
user100 [1]

<u>Answer:</u>

<em>4.5 L water we have in litres (L).</em>

<em><u></u></em>

<u>Explanation:</u>

Q=m\times c \times \Delta T

where

\Delta T = Final T - Initial T

Q is the heat energy in calories

c is the specific heat capacity (for water 1.0  cal/(g℃))  

m is the mass of water

Plugging in the values  

\\$45000 \mathrm{cal}=m \times 1.0 \frac{\mathrm{cal}}{\mathrm{g}^{\circ} \mathrm{C}} \times\left(35^{\circ} \mathrm{C}-25^{\circ} \mathrm{C}\right)$\\\\$45000 \mathrm{cal}=m \times 1.0 \frac{\mathrm{cal}}{\mathrm{g}^{\circ} \mathrm{C}} \times 10^{\circ} \mathrm{C}$\\\\$m=\frac{45000 \mathrm{cal}}{1.0 \frac{\mathrm{cal}}{\mathrm{g}^{\circ} \mathrm{C}} \times 10^{\circ} \mathrm{C}}$\\\\$m=4500 \mathrm{g}$\\\\Density of water $=\frac{\text { mass }}{\text { volume }}$

So,

Volume of water = mass/density

\\\\=\frac{4500 \mathrm{g}}{\frac{1.09}{\mathrm{mL}}}=4500 \mathrm{mL}$$

=4.5 L (Answer)
