Answer:
a theory of a experiment and the experiment acts like a judge determining if the hypothesis is right or wrong from the final test result
Explanation:
C = Carbon
If you look in a periodic table and see the mass number for carbon. Its estimated around 12.
I believe it's between 1-2 moles.
All you have to do is 13/12 which will give yoy the estimated answer which is around 1.08 mole.
The percent composition of each element can be calculated as follows:
% composition = (mass of element / total mass) * 100
The total mass of the quarter is given to be 5.670 grams
Mass of Cu = 5.198 grams
Mass of Ni = 0.472 grams
Substitute in the above equation to get the mass percentage of each element as follows:
% of Cu = (5.198/5.670) * 100 = 91.675%
% of Ni = (0.472/5.670) * 100 = 8.325%
I believe the correct answer from the choices listed above is the third option. Scientists who possess honesty always report their observations and results truthfully. It <span> connotes positive and virtuous attributes such as integrity, truthfulness, straightforwardness. Hope this answers the question.</span>
