Answer from: jennyferluna0216

The molarity of the solution is 0.1818 m.

What is molality?

Molality is the measure of the moles of any solute in a solution per unit kg of the solvent.

The density of water is 1 g/ml

The volume will be 725 ml

The density of acetic acid is 1.05 g/ml

Calculating the molarity

$\rm CH_3CO_2H = \dfrac{8\;g}{725g \times 7.61g} \times \dfrac{1000ml}{1\;L} \times \dfrac{1\;mol}{60.05\;g} = 0.1818 \;M$

Thus, the molarity of acetic acid is 0.1818 m

Answer from: darajeanty2004p7cu4m

Hello!

First, we can assume the density of water to be 1 g/mL, so the volume of water would be 725 mL. The density of Acetic Acid (Pure) is 1,05 g/mL so 8 grams would represent 7,61 mL

Now we can apply the following conversion factor to calculate the molarity of the solution, using the molar mass of Acetic Acid:

$[CH_3CO_2H]=\frac{8 g_{CH_3CO_2H} }{725 mL + 7,61 mL}* \frac{1000 mL}{1 L}* \frac{1 mol_{CH_3CO_2H} }{60,05 g_{CH_3CO_2H} }$

[CH_3CO_2H]=0,1818 M

So, the concentration of acetic acid would be 0,1818 M

Have a nice day!

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃ → 3 nicl₂ + 2 albarium and copper bromideba + cubr → no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn → znso₄ + na

Answer from: Quest

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
