Answer:
1 litre of 1.0 M NaCl
Explanation:
When an ionic compound dissolves in water, it dissociates into ions. Consider the dissolution of sodium chloride in water;
NaCl(s) ------> Na^+(aq) + Cl^-(aq)
Hence, two solute particles are obtained from each formula unit of NaCl, a greater concentration of NaCl will contain a greater number of sodium an chloride ion particles.
Glucose is a molecular substance and does not dissociate in solution hence it yields a lesser number of particles in solution even at the same concentration as NaCl
Answer:
Its B I just took the test and got a 100%
Explanation:
Answer:
the correct ans
Explanation:
The quantitative amount of energy that is necessary to provide to a substance whose temperature has to be increased is depicted as heat capacity. When the temperature is changed by one degree Celsius and the amount is fixed to one gram, then the heat capacity is depicted as specific heat capacity.
Metallic bonds result when electrons are shared equally.
Answer:
the answer is Z b/c wehave to forces and they have different direction. then search the sum of the forces. thus we gain 40 N to right.
