<h3>Answer:</h3>

CuSO₄

<h3>Explanation:</h3>

The compounds that conduct electricity when dissolved in water are known as electrolytes.
Electrolytes may be defined as compounds that conduct electricity either in aqueous or molten form, due to the presence of mobile ions.
Electrolytes are therefore decomposed by passing an electric current through them.
Examples of electrolytes include CuSO₄, NaOH, NaCl, etc.
Non-electrolytes, on the other hand, do not conduct electricity and cannot be decomposed through electrolysis.

5. Calculate the decrease in temperature when 6.00 L at 20.0 °C is compressed to 4.00 L.

Kazeer [188]

Answer: 195.3 K

Explanation: Use Charles Law to get T2

Charles Law V1 / T1 = V2 / T2

Derive the equation to find T2

T2 = V2T1 / V1

Convert temperature into K

T1 = 20.0 °C + 273 = 293 K

Substitute the values:

4.00 L x 293 K / 6.00 L = 195. 3 K

What volume of o2 is needed to react fully with 720. Ml of nh3

Galina-37 [17]

Ammonia undergoes combustion with oxygen to produce nitric oxide and water. The volume of the oxygen required to react with 720 ml of ammonia is 900 ml.

<h3>What is volume?</h3>

Volume is the area occupied by the substance and is the ratio of the mass to the density.

At STP, 1 mole of gas occupies 22.4 L of volume

Given,

Volume of ammonia reacted = 0.720 L

The combustion reaction is shown as,

$\rm 4NH_{3} + 5O_{2} \rightarrow 4NO +6H_{2}O$
