Answer:
B im so sorry if its wrong im sure it right
Explanation:
see it has the lowest specific heat so it wouldnt cool because of the bionestint particles
Answer:
See explanation below.
Explanation:
In the older procedure, the solution is cooled so quickly that the recrystallization can be less effective. By allowing the solution to cool slowly, the maximum amount of crystal is formed, and also the impurities are trapped, so the process is more controlled than by the older one.
You know that neutrons<span> are found in the nucleus of an </span>atom<span>. Under normal conditions, protons and </span>neutrons<span> stick together in the nucleus. During radioactive decay, they may be knocked out of there. </span>Neutron<span> numbers are able to change the mass of </span>atoms<span>, because they weigh about as much as a proton and electron together.</span>
