If 0.094 moles of magnesium react with excess oxygen, how many moles of magnesium oxide would be formed?

VMariaS [17]

The equation for this reaction is

$\text{Mg}+\text{O} \longrightarrow \text{MgO}$

This means that for every mole of magnesium consumed, 1 mole of magnesium oxide is produced.

So, the answer is <u>0.094</u> moles.

Suppose a layer of oil is on the top of a beaker of water. Water in many oils is slightly soluble, so its concentration is so lo

rodikova [14]

Explanation:

It is given that energy to transfer one water molecule is $2.208 \times 10^{-20}$ J/molecule

As it is known that in 1 mole there are $6.022 \times 10^{23}$ atoms.

So, energy in 1 mole = $2.208 \times 10^{-20} \times 6.022 \times 10^{23}$ J/mol

= 13.3 kJ/mol

As, $log \frac{k_{2}}{k_{1}} = \frac{E_{a}}{2.303 \times 8.314 atm L/mol K} \times \frac{T_{2} - T_{1}}{T_{1}T_{2}}$

Putting the given values in the above formula as follows.

$log \frac{k_{2}}{k_{1}} = \frac{E_{a}}{2.303 \times 8.314 atm L/mol K} \times \frac{T_{2} - T_{1}}{T_{1}T_{2}}$

$log \frac{k_{2}}{k_{1}} = \frac{13.3 kJ/mol}{2.303 \times 8.314 atm L/mol K} \times \frac{293 K - 283 K}{283K \times 293 K}$

$log \frac{k_{2}}{k_{1}}$ = 0.08377

$\frac{k_{2}}{k_{1}}$ = 1.213 = $\frac{Concentration_{2}}{Concentration_{1}}$

$Concentration_{2}$ = $1.213 \times Concentration_{1}$

= $1.213 \times 9 \times 10^{-4}$

= $10.915 \times 10^{-4}$ water molecules per oil molecule

Thus, we can conclude that the equilibrium concentration at 293 K, assuming that nothing else changes is $10.915 \times 10^{-4}$ .

What was the molecular geometry for SC16?

nikdorinn [45]

Answer:

I'm assuming this is for the SCl₆ compound and not SC₁₆? If so, the molecular geometry is octahedral.

Explanation:

There are 6 regions and zero lone pairs surrounding the central atom (S).

What is the mass of a proton equal to

ExtremeBDS [4]

The mass of a proton = 1.6726219 × 10^-27 kg.

It’s almost the exact same number as the mass of a neutron, which is 1.674927471×10^-27 kg. The mass of an electon is much less, even negligible.

I hope this helped you out!
