<span>The vaporization of br2 from liquid to gas state requires 7.4 k/cal /mol.</span>
Hello!
Your answer is A.. Earth's core is the most dense layer and it consists of the outer core and the inner core.
Hope this helps :))
I believe that the answer is 12 because there is already 3 O molecules and since its in parentheses with 3 outside it that means that there are 3 of those CO molecules meaning that for every 1 CO there will be 3 O’s so 3, four times Is 12
The density does not change because it is still the same liquid as before
