Determine the number of valence electrons in each of the following neutral atoms.

Harlamova29_29 [7]

Answer:

Fluorine = 7 v.e.

Sulfur = 6 v.e.

Oxygen = 6 v.e.

Nitrogen = 5 v.e.

Carbon = 4 v.e.

Explanation:

Valence electrons can be easily determined by understanding groups (columns). Every element in. . .

column 3A (13) = 3 v.e.

column 4A (14) = 4 v.e.

column 5A (15) = 5 v.e.

column 6A (16) = 6 v.e.

column 7A (17) = 7 v.e.

How many moles are in 5.60 x 10^23 atoms of Na? How many moles of H2 can be formed from this amount of Na?

alisha [4.7K]

Answer:

$\large \boxed{\text{A. 0.930 mol Na; B. 0.465 mol of H}_{2}}$

Explanation:

A. Moles of Na

1 mol Na atoms = 5.60 × 10²³ atoms of Na

$\text{Moles of Na } = 5.60 \times 10^{23} \text{ atoms Na} \times \dfrac{\text{1 mol Na}}{6.022 \times 10^{23}\text{ atoms Na}}\\\\= \text{0.930 mol Na}\\\text{There are $\large \boxed{\textbf{0.930 mol Na}}$ in 5.60 $\times 10^{23}$ atoms of Na.}$

B. Moles of hydrogen

You haven't given the equation for the reaction. However, we can write an equation

2Na + 2HX ⟶ 2NaX+ H₂

n/mol: 0.930

1 mol of H₂ is formed from 2 mol of Na

$\text{Moles of H}_{2} = \text{0.930 mol Na} \times \dfrac{\text{1 mol H}_{2}}{\text{2 mol Na}} = \textbf{0.465 mol H}_{2}\\\\\text{You can form $\large\boxed{\textbf{0.465 mol of H}_{2}}$}$
