Chemistry
1 answer:
Oduvanchick [21]3 years ago
5 0

Answer: 0.25 mol

Explanation:

Use the formula n=N/NA

n= number of mols

N =  number of particles

Nᵃ = Avogadros constant = 6.02 x

So, n=

The 10 to the power of 23 cancels out and you are left with 1.505/6.02, which is approximately 1/4. This is the same as 0.25 mol.

Hope this helped :)

6) What types of atomic orbitals are in the third principal energy
Bumek [7]

Answer:

Types of atomic orbitals present in the third principal energy are <u>s, p and d only .</u>

Explanation:

  • <u>OPTION A-:  s and p atomic orbitals -</u> these two orbitals are present in second principal energy level. Therefore , the option is incorrect.
  • <u> OPTION B-: p and d only -</u> This option is wrong as there is no such principal level energy where , s atomic orbital is absent .

  • <u>OPTION C-: s , p and d only -</u>these orbitals are present in<u> third principal energy level</u>. The third major level of energy has one orbital, three orbitals of p, and five orbitals of d, each of which can contain up to 10 electrons. The third stage thus holds a maximum of 18 electrons. This option is correct .
  • <u>OPTION D-: s , p, d and f only -</u>There is also a f sublevel at the <u>fourth and higher stages,</u> containing seven f orbitals, which can accommodate up to 14 electrons at most. Therefore, up to 32 electrons will hold the fourth level: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals. This option is incorrect .

<u>Thus , the correct option is C (s , p and d only .)</u>

vovangra [49]
This question is incomplete. Luckily, I found the same problem which is shown in the attached picture. To answer the question, we must know how the size and charge affect the lattice energy. The answer is: lattice energy increases with the increasing charge of the ions, and decreasing radius of the atoms. <em>Therefore, the ranking would be: A < B < C</em>.

If 10g of sodium react with an unlimited amount of chlorine how much sodium chloride will get produced?
puteri [66]

Answer: Amount of  sodium chloride produced is 25.43 grams.

Explanation:

To calculate the moles:

\text{Number of moles}=\frac{\text{Given mass}}{\textMolar mass}}

Given: Mass of sodium = 10 g

Molar mass of sodium = 23g/mol

\text{Moles of sodium}=\frac{10g}{23g/mol}=0.4347mol

The balanced equation is:

2Na+Cl_2\rightarrow 2NaCl

By Stoichiometry of the reaction,

2 moles of sodium produces 2 moles of sodium chloride

So, 0.4347 moles of sodium will produce =\frac{2}{2}\times 0.4347=0.4347mol of sodium chloride.

Molar mass of sodium chloride = 58.5 g/mol

Putting values in equation 1, we get:

0.4347mol=\frac{\text{Mass of NaCl}}{58.5g/mol}=25.43g

Hence, amount of sodium chloride produced is 25.43 grams.
