Troyanec [42]

Answer:

That's a really cool question. Is a human was frozen, do you mean like, in a cold environment or literally ice? If so ice, then they might die from suffocation? But if they were burning the next, either in the desert or on fire, they might have already died from hypothermia or suffocation from the ice? Dunno.

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 $\large\boxed{\textbf{0.465 mol of H}_{2}}$}$
