Answer:

The oxidation number are

NH₃: -3

HNO₃ : +5

NO₂ : +4

Explanation:

The oxidation number is calculated considering that

a) oxidation number of hydrogen is +1 in all compounds except hydrides

b) oxidation number of oxygen is -2 in all compound except peroxides, superoxides and compound of fluorine.

a) NH₃ : let the oxidation number of nitrogen is "x"

x + 3 (+1) = 0

Therefore x = -3

b) HNO₃

Let the oxidation number of nitrogen is "x"

+1 + x +3(-2) = 0

x = -5.

c) NO₂

Let oxidation number of nitrogen ix "x"

x + 2(-2)= 0

x = +4

A slice of Swiss cheese contains 48 mg of sodium

Nookie1986 [14]

Answer: grams=0.048g, ounces=0.0017oz, 0.00011lb

Explanation:

Stoichiometry

48 mg x 1 g

÷ 1000 mg = 0.048 g

48 mg x 1 g x 16 oz

÷ 1000 mg ÷ 453.6 g = 0.0017 oz

48 mg x 1 g x 1 lb

÷ 1000 mg ÷ 453.6 g = 0.00011 lb

When the pH of a solution changes from a pH of 5 to a pH of 3, the hydronium ion concentration is

gizmo_the_mogwai [7]

Answer : The correct option is, (D) 100 times the original content.

Explanation :

As we are given the pH of the solution change. Now we have to calculate the ratio of the hydronium ion concentration at pH = 5 and pH = 3

As we know that,

$pH=-\log [H_3O^+]$

The hydronium ion concentration at pH = 5.

$5=-\log [H_3O^+]$

$[H_3O^+]=1\times 10^{-5}M$ ..............(1)

The hydronium ion concentration at pH = 3.

$3=-\log [H_3O^+]$

$[H_3O^+]=1\times 10^{-3}M$ ................(2)

By dividing the equation 1 and 2 we get the ratio of the hydronium ion concentration.

$\frac{[H_3O^+]_{original}}{[H_3O^+]_{final}}=\frac{1\times 10^{-5}}{1\times 10^{-3}}=\frac{1}{100}$

$100\times [H_3O^+]_{original}=[H_3O^+]_{final}$

From this we conclude that when the pH of a solution changes from a pH of 5 to a pH of 3, the hydronium ion concentration is 100 times the original content.

Hence, the correct option is, (D) 100 times the original content.

Draw the Lewis structure for the molecule Carbon Dioxide, Co, and predict the molecular geometry.

Blababa [14]

Answer:

Lewis Structure:

Explanation:

CO2 Lewis Structure

So CO2 = 4 + 6(2) = 16. So, total valence electrons are 16. Carbon is the least electronegative that means it stays at the center. So, put the Carbon in the middle and then set the oxygen either side of that.
