There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.

Answer:

Fluorine is a non-metal, fills its shell by gaining one electron and becomes a negatively charged ion.

Explanation:

Fluorine have seven electrons in its outermost shell. This means that fluorine is located in Group 17(Halogens) in the Periodic Table. Note that halogens are non-metal elements. So fluorine is a non-metal.

Fluorine fills its shell by gaining one electron because it only needs one electron to achieve stable octet electron arrangement. ( it's easier to gain one electron than to lose all seven electrons in the outermost shell)

As fluorine atom gain one electron to achieve stable octet electron arrangement, its number of electrons becomes greater than its number of protons. So it becomes a negatively charged ion.

Hippuric acid (HC9H8NO3)(HC9H8NO3), found in horse urine, has pKa=3.62pKa=3.62. Part A Calculate the pHpH in 0.140 MM hippuric a

Oxana [17]

Answer:

The pH in 0.140 M hippuric acid solution is 2.2.

Explanation :

Dissociation constant of the acid = $K_a$

$pK_a=-\log[K_a]$

$3.62=-\log[K_a]$

$K_a=2.399\times 10^{-4}$

Concentration of hippuric acid = c = 0.140 M

$HC_9H_8NO_3\rightleftharpoons C_9H_8NO_{3}^-+H^+$

Initially

c 0 0

At equilibrium

(c-x) x x

Concentration of acid = c $[HC_9H_8NO_3]=0.140 M$

Dissociation constant of an acid is given by:

$K_a=\frac{[C_9H_8NO_{3}^-][H^+]}{[HC_9H_8NO_{3}]}$

$K_a=\frac{x\times x}{(c -x)}$

$2.399\times 10^{-4}=\frac{x\times x}{(0.140 -x)}$

Solving for x:

x = 0.005677 M

$[H^+]=x = 0.005677 M$

The pH of the solution :

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

$pH=-\log[0.005677 M]=2.246\approx 2.2$

The pH in 0.140 M hippuric acid solution is 2.2.
