The number of solute particles increases and the boiling point increases ( A )

As more sodium chloride is added, the number of solute particles contained in the dilute solution will increase which will have a direct positive effect on the boiling point ( i.e increase in boiling point ).

As more solute ( sodium chloride ) is added the molar concentration of NaCl solute will increase as well. The change in boiling point of a solution can be expressed as :

ΔTb = Kb * m

where : Kb = elevation constant , m = Molar conc of solute, ΔTb = change in boiling point.

Hence we can conclude From the expression above an increase in molar concentration of Nacl will lead to an increase in the boiling point of the solution.

Answer from: izzyisnotfizzy

The number of solute particles increases, and the boiling point increases.

Explanation:

It is known from colligative properties that adding solute to the solvent will cause elevation of boiling point.Elevation of boiling point (ΔTb) can be expressed as:

ΔTb = Kb.m,

where, Kb molal boiling point elevation constant.

m is the molal concentration of solute.

Adding more sodium chloride to the solution:

will increase the number of solute particles and also will increase the molal concentration of NaCl solute.

∵ ΔTb ∝ m.

So, the boiling point increases.Thus, the right choice is:

The number of solute particles increases,

Answer from: Quest

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
