Silver tarnishes in the presence of oxygen and hydrogen sulfide according to the following equation:
4Ag(s) + 2H_S(g) + O2(g) → 2Ag, S(s) + 2H2O(1)
tarnish
Usually, H, S is the limiting reactant. If a silver spoon is placed in a container
that holds 62.1 mL of H, S at 1.15 atm and 23.0°C, how many grams of silver
on the spoon will tarnish?

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

they are both synthetic elements

explanation:

d

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
