Answer:

The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.

To make a sarurated solution, 36 g of sodium chloride is dissolved in 100 g of water at 293 k . Find its concentration at this t

nexus9112 [7]

Answer:

The answer is " $26.47\%$ "

Explanation:

Sodium chloride solute mass $=36 \ g$

Solvent water mass $=100\ g$

Calculating the solution mass = Solute mass + solvent mass

$= 36\ g +100\ g\\\\ = 136\ g\\\\$

Calculating the percentage of concentration:

$= \frac{solute\ mass}{solvent\ mass} \times 100\\\\=\frac{36\ grm}{136\ grm} \times 100\\\\=0.2647 \times 100\\\\=26.47 \%$

When the NaOH dissolves, the temperature of the solution increases from 18.2 C to 24.5 C. Assuming the specific heat and density

ELEN [110]

Answer:

The heat of solution is 1.05 kJ/mol

Explanation:

NaOH → Molar mass 40 g/m

This is the mass in 1 mol

Calorimetry formula:

Q = m . c . ΔT

ΔT = T° final - T° initial = 24.5°C - 18.2°C = 6.3°C

mass = 40 g

c = 4.186 kJ/kg°C (the same as water)

So we have to convert 40 g to kg

40 g/1000 = 0.04 kg

Q = 0.04 kg . 4.186 kJ/kg°C . 6.3 °C = 1.05 kJ
