Hello
the answer is false becasue the amount of atoms depend on the different elements
hope this helps
plz mark me as brainliest
The extraction is done by electrolysis. The ions in the aluminium oxide must be free to move so that electricity can pass through it. Aluminium oxide has a very high melting point (over 2000°C) so it would be expensive to melt it. The use of cryolite reduces some of the energy costs involved in extracting aluminium.
The correct option in here is the first one: <span>pentane-1,5-diamine. This is also known as cadaverine. This is a common compund that produces that unpleasant odor from the fish. </span>
Hello, let me break this down for you! :)
A is your energy of your reactants, B is your activation energy, so the
total value could be found from B-Y. C is the value of your energy of
your products. X is your delta H value. So in this, your products are
higher energy than the reactants, so H is + and e2-E1 is positive so E2
>E1
Therefore your answers would just be <span>E2 > E1 and
</span><span>Hrxn<span> is positive.
Hope this helps! If you have any other questions or need further explanation just let me know! :)
