The theoretical yield and the percent yield are calculated as shown. 0.222gO2 and 87.8% Did you perform the calculations correctly? Yes, I got the correct theoretical yield and percent yield. No, I got the correct theoretical yield but calculated the percent yield incorrectly. No, I calculated the theoretical yield incorrectly, so my percent yield calculation was also incorrect. No, I used the correct equations, but I got the wrong answer because of a math error.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

i believe the answer is a.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
