If they're half life, wouldn't that mean every 5730 years I would double? So 12.5 x 2= 25, 25 x 2 = 50, and 50 x 2 = 100% carbon-14. It doubled 3x so the 5730 x 3 = amount of years the volcano erupted

It erupted 17,190 years ago.
It has a half life of 5,730 years. Therefore, when it has 50% remaining, it has lived for 5,730 years. When it has 25% remaining, it has lived for 11,460 (5730+5730). When it has 12.5% remaining (25/2), then it has lived 17,190 years (11,460 + 5730).

Which of these phrases accurately describe disproportionation? Check all that apply.
Olin [163]

Answer:

A single compound is simultaneously oxidized and reduced.

Explanation:

In chemistry, disproportionation is a simultaneous oxidation and reduction of a single chemical specie.

What this means is that; in a disproportionation reaction, only one compound is both oxidized and reduced. This implies that two products are formed during disproportionation. One is the oxidized product while the other is the reduced product.

Consider the disproportionation of CuCl shown below;

2CuCl -----> CuCl2 + Cu

Here, CuCl2 is the oxidized product while Cu is the reduced product.
