What are two ways in which density has practical importance?

Marta_Voda [28]

density is how much matter is packed into one area. so the higher density the more likely it is to be heavier. for example, cork has a very low density and iron has a higher density.

The electronic configuration of an element is given below.

Amiraneli [1.4K]

The statement which is true about the reactivity of element with 1S²2S²2P⁶3S¹ is

it is reactive because it has to lose one electron to have a full outermost energy level.

Explanation

Element with 1S²2S²2P⁶3S¹ electron configuration is a sodium metal.

sodium has one electron in the outermost energy level.

for sodium to have a full outermost energy level ( 8 electrons) it loses the 1 electron in 3S¹ to form a positively charged ion. (Na⁺)

The pH of 0.10 M solution of an acid is 6. What is the acid dissociation constant of the acid?

svlad2 [7]

Answer: Dissociation constant of the acid is $10^{-11}$ .

Explanation: Assuming the acid to be monoprotic, the reaction follows:

$HA\rightleftharpoons H^++A^-$

pH of the solution = 6

and we know that

$pH=-log([H^+])$

$[H^+]=antilog(-pH)$

$[H^+]=antilog(-6)=10^{-6}M$

As HA ionizes into its ions in 1 : 1 ratio, hence

$[H^+]=[A^-]=10^{-6}M$

As the reaction proceeds, the concentration of acid decreases as it ionizes into its ions, hence the decreases concentration of acid at equilibrium will be:

$[HA]=[HA]-[H^+]$

$[HA]=0.1M-10^{-6}M$

$[HA]=0.09999M$

Dissociation Constant of acid, $K_a$ is given as:

$K_a=\frac{[A^-][H^+]}{HA}$

Putting values of $[H^+],[A^-]\text{ and }[HA]$ in the above equation, we get

$K_a=\frac{(10^{-6}M).(10^{-6}M)}{0.09999M}$

$K_a=1.0001\times 10^{-11}M$

Rounding it of to one significant figure, we get

$K_a=1.0\times 10^{-11}M\approx 10^{-11}M$

A three-component mixture of organic compounds in diethyl ether consists of a carboxylic acid, an amine base, and a neutral comp

Dmitrij [34]

Answer:the sodium carboxylate salt

Explanation:

The reaction between the carboxylic acid and the sodium hydroxide yields a sodium carboxylate. This sodium carboxylate is an ionic in nature; RCCOO-Na+. This can effectively interact with water and remain in the aqueous phase since it is composed of the carboxylate ion and sodium ion in solution. The aqueous phase always contains water soluble ionic substances of which the sodium carboxylate is a typical example of such.
