Answer:
Low mass star phases
Explanation:
Helium fuses into carbon, the core of the star collapses. Once this happens, the outer layers become exhausted from the weight and this leads a planetary nebula to be formed from the outer layers. The core of the star remains a white dwarf for some time, but eventually it cools down and evolves to a black dwarf.

E cell = 1.962 V
<h3>Further explanation</h3>
Given
E° cell = 2.00 V
Required
E cell at 298 K
Solution
The potential cell for nonstandard conditions we can use the Nernst equation
For temperature T = 298 K,
Reaction
3A(s) + B+3(aq) → 3A+(aq) + B(s)
Half Reaction
3A(s)⇒3A⁺(aq)+3e⁻
B⁺³(aq)+3e⁻⇒B(s)
n = 3 (3 electron transfer)
Q = the reaction quotient :
E cell :
