Carbon dating has<span> given archeologists a more accurate method by which they </span>can<span> determine the age of ancient artifacts. The </span>halflife<span> of </span>carbon 14<span> is </span>5730<span> ± 30 </span>years<span>, and the method of dating lies in trying to determine how </span>much carbon 14<span> (</span><span>the radioactive isotope of carbon) is present in the artifact and comparing it to levels</span>
it is water energy :) this is easy
Answer:
I don't know chemistry
Explanation:
because this is the hardest subject in the world nobody can solve it so do yourself ok Beta
He was involved in the mapping of venus and mars
Answer:
3.- The same
Explanation:
1.- In the reactants you need to calculate the charges that you have:
2 Al(s) = zero, because the aluminum is in it based formed (that mean without charge).
3 Cu2+ = 3 x 2+ = 6+ That is the total positive charges that copper collaborate in this reaction.
2.- Then calculate the charges on the products:
2 Al3+ = 2 x 3+ = 6+ charges from the aluminum.
3 Cu(s) = zero, because the copper in this case is in the base form
3.- In this way, the charges at the begging (6+) and at the end (6+) are the same.
