Answer:
The answer to your question is: C2 = 0.0004 M
Explanation:
Data
pH = 2.5; V = 1.0 L
V2 = 8.0 L C2 = ?
Formula
C1V1 = C2V2
C2 = C1V1 / V2
pH = -log[H⁺]
Process
[H⁺] = antilog -pH
[H⁺] = antilog (-2.5)
[H⁺] = 0.003 M = C1
Finally
(0.003)(1 l) = C2(8)
C2 = 0.003 / 8
C2 = 0.0004 M

The decay process that is demonstrated by the equation above would be a beta decay. This type of radioactive decay involves the emission of a beta particle. It happens when one of the protons is transformed in the other. The beta particle here is represented by <span>0 -1e.</span>
Answer:
The outer shell of the new star will start to expand.
Explanation:
The new star will continue to glow for millions or even billions of years. As it glows, hydrogen is converted into helium in the core by nuclear fusion. The core starts to become unstable and it starts to contract. The outer shell of the star, which is still mostly hydrogen, starts to expand.
