2 electron orbitals is the correct answer
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.

The answer is A. A falling barometer means a decrease in air pressure. This is caused by an increase in the local temperatures that warm the air and make it less dense. Clouds start forming when the warm humid air starts to rise and cool. The water moisture turns into water droplets.
Answer:
4NH3 + 5 O2 → 4 NO + 6 H2O
Explanation:
The formula of ammonia is NH3. Oxidise means adding 02. This will result in Nitrogen(II)oxide which is NO, and H20.
On the left side we have 3xH and on the right side we have 2x H. To get the same amount we multiply the left side bij 2 and the right side by 3.
This gives us 2N on the left side, so we multiply NO by 2, to get the same amount of N.
This gives us 5x O at the right side, so to get the same amount we multiply O2 by 5/2 ( we already got 2x O).
This gives us 2NH3 + 5/2 O2 → 2NO + 3H20
We multiply by 2 to get rid of fractions, which will give us:
4NH3 + 5 O2 → 4NO + 6H20
