Consider the half reactions below for a chemical reaction. Zn——>Zn2+ (aq) + 2e-
Cu2+ (aq) + 2e- ——> Cu(s)
What is the overall equation for this chemical reaction?
Zn(s)+ Cu2+ (aq)
Zn2+ (aq) + Cu(s)
Zn(s) + Cu2+ (aq) Cu2+ (aq) + 2e-
Zn2+ (aq) + Cu(s)-> Cu2+ (aq) + Zn(s)
Zn2+ (aq) + 2e--> Cu2+ (aq) + 2e-

Describe the chemical reaction based on the chemical equation below. also, explain whether the equation is balanced.

Three cards with holes are arranged in a straight line. a light is shined through the first card’s hole and travels through all three cards. what does this tell you about light rays? a) that light is reflected b) that light is refractive c) that light travels in a straight line d) that light does not travel in a straight line

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
