Answer:
KNO₃ is an electrolyte.
Explanation:
Electrolyte is any specie which when dissolved in water produces a cation and anoin. Electrolytes has the ability to conduct electricity. In given options O₂, Xe and C₃H₈ are non electrolytes because they cannot dissociate into cation and an anion due to their covalent bonds or monoatomic nature. The dissociation of Potassium Nitrate is as follow,
KNO₃ → K⁺ ₍aq₎ + NO₃⁻ ₍aq₎
The formula for phosphorus is P4
Energy can be conserved by efficient energy use.
Answer: Option A
<u>Explanation:</u>
Energy can be transferred from one form to another, but it cannot be destroyed or created. So it can be conserved if efficiently used. Thus efficient usage of energy lead to conservation of energy. Due to conservation of energy, the forces can be renewable and non-renewable.
So, we should know how the input energy can be completely converted to another form of energy leading to efficient usage of energy without any loss. As if there is no loss, input energy will be equal to output energy leading to 100% efficiency.
Answer:
none of the above
Explanation:
because all of them are unstable
