Which of the following statements is false about drawing Lewis structures?

Chemistry
1 answer:

8 0

Answer:

c. N, P, and As can sometimes share more than 8 e-

Explanation:

Lewis structures are diagrams that show the valence electrons of atoms within a molecule. Valence electrons play a major role while drawing Lewis structures as only valence electrons can be shared with another molecule to form a bond.

N, P, and As can not share more than 8 e- because they have less valence electrons in their outer shell. N has only one valence electron, P and As has only 5 valence electrons so they can not share more than their valence electrons.

Hence, the correct answer is "c. N, P, and As can sometimes share more than 8 e-".

Calculate the grams of sodium hydroxide formed when 2.24 moles of sodium oxide react with water
Romashka [77]
The balanced reaction is 
Na2O + H2O --> 2NaOH

If 2.24 moles of sodium oxide react, that means 4.48 moles of NaOH is formed as it is a 1 to 2 stoichiometric relationship.

Now we multiply by the molar mass to get grams.

4.48 moles NaOH * (39.997 grams/1 mole) = 179.2 grams

Your answer is 179. grams.

65 g of hydrogen chloride (hcl) is dissolved in water to make 5.0 l of solution. what is the ph of the resulting hydrochloric ac
sashaice [31]
65 grams of HCl = 65/36.5 moles of HCl = 1.78 moles
1.78 moles of HCl dissolved to make a 5 litres of solution has a concentration of 1.78/5 = 0.36 mol/dm^3 (Note: 1 litre = 1 cubic decimetre)

In a strong acid, such as HCl, [H+] = [acid], so [H+] = 0.36

To calculate pH, we have to take the negative logarithm of the concentration of protons

So, -log(0.36) = 0.45

Hope I helped!! xx

Why atomic mass is an average vàlue​
lukranit [14]

Answer:

The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. It is a decimal number.

Explanation:

Atomic Mass and Mass Number Example :

Hydrogen has three natural isotopes: 1H, 2H, and 3H. Each isotope has a different mass number.

1H has 1 proton. Its mass number is 1. 2H has 1 proton and 1 neutron. Its mass number is 2. 3H has 1 proton and 2 neutrons. Its mass number is 3. 99.98% of all hydrogen is 1H 0.018% of all hydrogen is 2H 0.002% of all hydrogen is 3H Together, they give a value of atomic mass of hydrogen equal to 1.0079 g/mol.
