best and most correct answer among the choices provided by the question is </span>B.-2.71 V.</span>
Mg2+(aq) + 2e- -> Mg(s) E=-2.37 V
Cu2+(aq) + 2e- -> Cu(s) E =+ 0.34 V
Since Cu is acting as the anode, the equation needs to be
reversed.
Cu(s) -> Cu2+(aq) + 2e- E =- 0.34 V
Ecell= -2.37 V+ (- 0.34 V) = -2.71 V

Objects can have the same mass (but different <span>compositions). Only mass or volume cannot tell you if the object is solid or vo</span>lumes) or same volume (but different masses)
Answer:
what r the options that are there
Explanation:
Hello jamaicandoll!
What is the force on a body if the mass of the body is 2300g? (acceleration due to gravity = - 9.8m/s²) .
Given,
- Mass (m) = 2300 g = 2.3 kg
- Acceleration (a) = -9.8 m/s²
- Force (F) = ?
We know that, force = mass × acceleration.
So,
F = ma
F = 2.3 × -9.8
F =
