Softa [21]3 years ago

The concentration of cell is less than that of the solution .

Hence the cell will be called as hypotonic and the solution will be called as hypertonic.

in order to balance the concentration on the two sides of cell (inside and outside in the solution) there will be movement of solvent particles (through semipermeable membrane ) from cell (lower concentration of solute) to solution (higher concentration of solute).

Thus cell will shrink.

Consider the reaction.

Alekssandra [29.7K]

Answer:The correct answer is option C.

Explanation:

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

At STP, 1 mol of gas occupies 22.4 L of volume

So, 100.0 L volume of $NH_3$ will be occupied by :

$\frac{1}{22.4 L}\times 100.0 L=4.4642 moles$

According to reaction 2 moles $NH_3$ are obtained from 1 mole of $N_2$ .

Then,4.4642 moles of $NH_3$ will be obtained from :

$\frac{1}{2}\times 4.4642$ that is 2.2321 moles of $N_2$

Mass of $N_2$ gas:

Moles of $N_2$ gas Molar mass of $N_2$ gas:

$2.2321 mol\times 28 g/mol=62.4988\approx 62.50 g$

Hence, the correct answer is option C.

Do metals donate or accept electrons? what do they become after they donate/accept electrons?

valentinak56 [21]

Metal usually donates electrons. The concept behind this phenomenon is stability. The elements with the most stable electronic configuration are the noble gases in Group 5A. As a result, the other elements donate or accept electrons so that they would be like the noble gases. Since metals are past their nearest noble gas element, they have to shed their electrons. When they do, they become cations which are positively charged ions.
