Answer:
The answer you're looking for is B.C (6,3)
Hope this helps :)
None, because molecules are a group of two (or more) electrically bonded atoms. But there are gases not bonded due to their stability.
We are given the starting amount of Al metal to be used. This will be the starting point of the calculations. We do as follows:
74.00 g ( 1 mol / 26.98 g ) ( 1 mol Al2O3 / 2 mol Al ) ( 101.96 g / 1 mol ) = 139.83 g Al2O3 produced
Hope this answers the question. Have a nice day.
Their positive charge is located in a small region that is called the nucleus.
Explanation:
Ernest Rutherford in his gold foil experiment was able to demonstrate that the nucleus is made up of positive charges which occupies a small and tiny nucleus.
Rutherford bombarded a thin gold foil with alpha particles from a radioactive source.
- He observed that all the particles passed through but a small portion was deflected back.
- This led to his proposition of the nuclear model the atom.
