Answer:

1386g

Explanation:

Solubility of a solute is the ability of the solute to mix into a liquid (the solvent). It measures the highest amount of substance mixed into a liquid solvent while they are both at equal amounts.

if 14g dissolved in 100cm3

  the amount that will dissolve in 1000cm3 = 14 x 1000/ 100

                                                                      =1400g

To form a saturated solution, 1400 - 14 = 1386g must be added.

Find the normality of 0.321 g sodium carbonate in a 250 mL solution.
Radda [10]

Answer:

the normality of the given solution is 0.0755 N

Explanation:

The computation of the normality of the given solution is shown below:

Here we have to realize the two sodiums ions per carbonate ion i.e.

N = 0.321g Na_2CO_3 × (1mol ÷ 105.99g)×(2eq ÷ 1mol)

= 0.1886eq ÷ 0.2500L

= 0.0755 N

Hence, the normality of the given solution is 0.0755 N

When an electron is displaced in a semiconductor, the hole that's left behind is
geniusboy [140]
<span>answer is A : attracted to the negative terminal of the voltage source
 I think, that the "hole"moves as it captures a free electron leaving another hole in a slightly different place. The electron leaving leaves a net + charge, which is attracted to the negative terminal. Because the "hole" behaves as a positive charge it is attracted towards the negative terminal.</span>
