<span>Which best explains why some radioisotopes decay in a decay series?
</span><span>
The correct answer is:
Some unstable materials decay radioactively into other unstable materials.
</span>Radioactive decay a the spontaneous process through which an unstable atomic nucleus breaks into smaller, more stable fragments. <span>It's basically a matter of thermodynamics. Every atom seeks to be as stable as possible. In the case of radioactive decay, instability occurs when there is an imbalance in the number of </span>protons<span> and </span>neutrons<span> in the atomic nucleus.</span>
After oil is naturally refined underground, the only way that a viable deposit of hydrocarbon can form is if the oil encounters some kind of trap.
I believe your answer is 40g 15*C I hope that helps.
I’ve come up with C. i apologize if it’s wrong
