A 581.2 mL sample of carbon dioxide was heated to 347 K.
svetlana [45]

Answer:

The temperature at 581.2 mL volume was 242.8 K.

Explanation:

Using Charle's law  

\frac {V_1}{T_1}=\frac {V_2}{T_2}

Given ,  

V₁ = 581.2 mL

V₂ = 830.5 mL

T₁ = ?

T₂ = 347 K

Using above equation as:

\frac {581.2\ mL}{T_1}=\frac {830.5\ mL}{347\ K}

T_1=\frac{581.2\times 347}{830.5}\ K=242.8\ K

<u>The temperature at 581.2 mL volume was 242.8 K.</u>

Q3. A student wanted to make blue copper sulfate crystals from green copper carbonate powder
CaHeK987 [17]

Heat the sulfuric acid solution and adding copper carbonate in it.

<h3>Improvement require in this experiment</h3>

The method could be improved by heating sulfuric acid solution and add copper carbonate into the solution of sulfuric acid. Add the copper carbonate until it is present in excess amount. After that filter the extra amount of copper carbonate so in this way the blue copper sulfate crystals are produced.
