How many moles of Al will be consumed when 0.400 mol of Al2O3 are produced in

Vladimir [108]

Answer:

C) 0.800 mol

Explanation:

4Al + 3O₂ → 2Al₂O₃

In order to convert from moles of Al₂O₃ into moles of Al, we'll need to use the stoichiometric coefficients, using a conversion factor that has Al₂O₃ moles in the denominator and Al moles in the numerator:

0.400 mol Al₂O₃ * $\frac{4molAl}{2molAl_2O_3}$ = 0.800 mol Al

So the correct answer is option C).

Consider an electron with charge âˆ’eâˆ’e and mass mmm orbiting in a circle around a hydrogen nucleus (a single proton) with cha

PtichkaEL [24]

Answer:

Explanation:

The net force on electron is electrostatic force between electron and proton in the nucleus .

Fc = $\frac{1}{4\pi\epsilon} \times \frac{e\times e}{r^2}$

This provides the centripetal force for the circular path of electron around the nucleus .

Centripetal force required = $\frac{m\times v^2}{r}$

$\frac{m\times v^2}{r}=\frac{1}{4\pi\epsilon} \times \frac{e\times e}{r^2}$

$v^2=\frac{e^2}{4\pi \epsilon m r}$

$v=(\frac{e^2}{4\pi \epsilon m r})^{\frac{1}{2} }$
