Answer:
By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.
Explanation:
Mass will increase drastically the GPE since mass since mass is a variable in the formula GPE= mgh. 2.
The moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.
The balanced chemical equation for the decomposition of Ammonia has been:
<h3>Computation for moles of Hydrogen produced</h3>
From the balanced chemical equation, decomposition of 2 moles of ammonia produces, 3 moles of hydrogen and 1 mole, nitrogen.
The moles of hydrogen produced along with 0.0351 mol nitrogen has been:
Thus, the moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.

As weight = mass × g so we have more weights on earth than on moon. Explanation: This is because gravitational force is immediately proportional to the mass of an object. Greater the mass, greater will be the gravitational force exerted by it and thus, more will be our weight
