The reaction N2O4↽−−⇀2NO2 is allowed to reach equilibrium in a chloroform solution at 25 ∘C . The equilibrium concentrations are 0.371 mol/L N2O4 and 2.04 mol/L NO2 . Calculate the equilibrium constant, Kc , for this reaction. study equilibrium the effect of anxiety (low vs. high) and stress (low vs. moderate vs. high) on test.

Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best known for altering behavior, worry can have negative effects on our physical health. Anxiety speeds up our heartbeat and breathing, concentrating blood flow to the parts of our brains that need it. You are getting ready for a challenging situation by having this extremely bodily reaction. Test equilibrium may be impacted by anxiety. According to studies, pupils with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have equilibrium that female students have greater levels of test anxiety than male students.

How many liters in .5 moles of co2
Alex Ar [27]
At STP, one mole of gas occupies 22.4 L of space. Assuming the conditions conform to STP
                                   volume CO2 = 0.5 mol * 22.4 L/1 mol
                                                          = 11.2 L
                                                          = 10 L
The answer with 1 significant figure is 10 L of CO2

How many atoms are in 6.28 moles of aluminum
tensa zangetsu [6.8K]

Answer:

3.78 x 10^24

Explanation:

I mol = 6.02X10^23 atoms

So,

6.28 mol A l    \frac{6.022 x 10^{23}}{1 mol}    = 3.78 x 10^{24} I did not round the last number

the full answer was, 3.78056 x 10^24

Please help!<br><br> Calculate the percent by mass of water in FeCl2 · 4H20.
Sedaia [141]

Answer:

36.23 %

Explanation:

Let's <em>assume we have 1 mol of FeCl₂ · 4H₂O</em>. In that case we would have:

  • 1 mol of FeCl₂, weighing 126.75 g (that's the molar mass of FeCl₂), and
  • 4 moles of H₂O, weighing (4 * 18 g/mol) 72 g.

Now we can <u>calculate the percent by mass of water</u>:

  • % mass = mass of water / total mass * 100%
  • % mass = \frac{72}{72+126.75} * 100% = 36.23 %

Which element is reduced in the following reaction: 2Mg+O₂ → 2MgO if Mg goes from 0 to +2 and O goes from 0 to -2?
Lyrx [107]

Answer:

O.

Explanation:

  • The element which is oxidized is the element that losses electrons and its oxidation state be more positive.
  • The element which is reduced is the element that gain electrons and its oxidation state be more negative.

<em> O goes from 0 to -2, so, it is the element that is reduced.</em>
