Answer:
KBr dissolved in water.
Explanation:
A substance conducts electricity as a result of the presence of mobile ions in the substance.
An ionic substance such as KBr when dissolved in water releases free ions which become charge carriers in solution hence the solution conducts electricity. Solid ionic substances such as solid KBr and solid baking soda do not conduct electricity because the ions are strongly bound to each other in the crystal lattice.
Molecular substances such as sugar and alcohol do not conduct electricity even in solution.

Answer:
Every single celled organism is able to survive because it carries out metabolic activities.
Metabolic activity is a set of chemical reactions which are needed for an organism to maintain it's life
Explanation:
the various types of metabolic processes keep an organism alive. There are various types of metabolic processes that takes place in the body of living organism.
These are cellular respiration, reproduction, excretion, digestion et cetera. Every living cell has these processes going on in their body to keep them alive.
Living organism need energy to carry out these processes which they get by eating food.

Answer: the boiling point elevation constant is 
Explanation:
Elevation in boiling point is given by:
= Elevation in boling point
i= vant hoff factor = 1 (for non electrolyte)
=boiling point constant = ?
m= molality
Weight of solvent (diethylether)= 330 g = 0.33 kg
Molar mass of solute (benzophenone)= 182 g/mol
Mass of solute (benzophenone) = 38.2 g
Thus the boiling point elevation constant is
