An empty beaker is weighed and found to weigh 23.1 g. Some potassium chloride is then added to the beaker and weighed again. The

GuDViN [60]

Answer:Mass of Potassium chloride =1.762g

Explanation:

Mass of empty beaker = 23.100 g

Mass of beaker with Potassium chloride = 24.862g

Mass of Potassium chloride = Final weight - initial weight = Mass of beaker with Potassium chloride - Mass of empty beaker = 24.862-23.100 = 1.762g

Four students are developing a model to illustrate covalent and ionic substances dissolving in

Liono4ka [1.6K]

The students with ionic bonds have a better understanding of what the model needs to illustrate.

Explanation:

When ionic compounds dissolve in water, they break apart into the ions that make them up through a process called dissociation.
When placed in water, the ions are attracted to the water molecules, each of which carries a polar charge.
If the force between the ions and the water molecules is strong enough to break the bonds between the ions, the compound dissolves.
The ions dissociate and disperse in solution, each ringed by water molecules to prevent reattachment.
The ionic solution turns into an electrolyte, meaning it can conduct electricity.
While covalent compounds dissolve in water they break apart into molecules, but not individual atoms.
Water is a polar solvent, but covalent compounds are usually nonpolar.
This means covalent compounds typically don't dissolve in water, instead making a separate layer on the water's surface.

Find the concentration of H+ ions at a pH = 11 and pH = 6. Then divide the concentration of H+ ions at a pH = 11 by the of H+ io

andrew11 [14]

Explanation:

When pH of the solution is 11.

$pH=-\log[H^+]$

$11=-\log[H^+]$

$[H^+]=1\times 10^{-11} M$ ..(1)

At pH = 11, the concentration of $H^+$ ions is $1\times 10^{-11} M$ .

When the pH of the solution is 6.

$pH=-\log[H^+]'$

$6=-\log[H^+]'$

$[H^+]'=1\times 10^{-6} M$ ..(2)

At pH = 6, the concentration of $H^+$ ions is $1\times 10^{-6} M$ .

On dividing (1) by (2).

$\frac{[H^+]}{[H^+]'}=\frac{1\times 10^{-11} M}{1\times 10^{-6}}=1\times 10^{-5}$

The ratio of hydrogen ions in solution of pH equal to 11 to the solution of pH equal to 6 is $1\times 10^{-5}$ .

Difference between the $H^+$ ions at both pH:

$1\times 10^{-6} M-1\times 10^{-11} M=9.99\time 10^{-7} M$

This means that Hydrogen ions in a solution at pH = 7 has $9.99\time 10^{-7} M$ ions fewer than in a solution at a pH = 6
