Answer: hello the experiment related to your question is missing but I will provide a more general answer within the scope of your question
answer :
presence of Impurities
Explanation:
The melting point of the crystals as obtained in the experiment will be close to but below reference melting points and will also melt slower because of the presence of impurities in the compound
Impurities alter the melting and freezing points from ideal freezing and melting points of compounds
Answer:
= 10 M or 10 moles/liter
Explanation:
Molarity is calculated by the formula;
Molarity = Moles/volume in liters
In this case;
The number of moles = 0.5 moles
Volume = 0.05 liters
Therefore;
Molarity = 0.5 moles/0.05 liters
= 10 M or 10 moles/liter
Thus the molarity is 10 M or 10 moles/liter
All the energy gets released i think
It is nontoxic, nonmetallic, odorless, tasteless, colorless
