During the first simulation, approximately of the radioactive atoms became stable after each half-life. a. 100% b. 50% c. 25% d. 10% during the second simulation, approximately of the radioactive atoms became stable after each half-life. a. 100% b. 50% c. 25% d. 10%

I'm not sure what do you mean by "first" and "second" simulation, however, the half-life of a radioactive element is the time after which 50% of the initial sample has decayed, and so it is the time after which 50% of the atoms have became stable.

So, the correct answer is B) 50%.

Is there a picture to go along with this

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
