The reactants of two chemical equations are listed. Equation 1: CuSO4 and NaOH
Equation 2: Fe and CuSO4

Based on the type of reaction, which reaction can be used to extract copper metal from copper sulfate solution?

A - Equation 2, because Fe being more reactive, replaces Cu from CuSO4
B - Equation 2, because Fe being more reactive, replaces S from CuSO4
C - Equation 1, because Na being more reactive, exchanges position with Cu in CuSO4
D - Equation 1, because Na being more reactive, exchanges position with S in CuSO4

B

Explanation:

B is the answer because equation 2

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.
