Which is not true of radioactive half-life? radioactive half-life is increased by heating the isotope. independent of the physical or chemical form of the isotope. the time required for the level of radioactivity in a sample to be cut in half. independent of the amount of radioactive material present?

"Radioactive half-life is increased by heating the isotope" is not true.

Explanation:

The radioactive half-life is the time required for half of any given amount of a substance (or isotope), to undergo radioactive decay.

This radioactive decay does not depend on the physical form of the substance nor it depends on the temperature.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
