Mass Number quantifies the number of protons and neutrons in the atom. Electrons are so small that they do not even matter in the calculation. Protons and Neutrons are approximately 1 A. Atomic Number refers to where the atom is on the periodic table, such as Hydrogen being Atomic Number 1, but also quantifies the number of protons. In your situation the atomic number is 32 meaning it is Germanium but also meaning it has 32 protons. When we add the number of protons and number of neutrons to find the mass number we do 32 (protons) + 31 (neutrons) to get a total mass number of 63. 63 is your answer.
dwarf planet is a planetary-mass object that is neither a planet nor a natural satellite. That is, it is in direct orbit of the Sun, and is massive enough for its gravity to crush itself into a hydrostatic equilibrium shape (usually a spheroid), but has not cleared the neighborhood of other material around its orbit.
asteroids are rocks
Answer:
SODIUM STEARATE — NaC18H35O2; Soap
Explanation:
Derived from edible fats (e.g. coconut, palm), sodium stearate is an incredibly common fatty acid salt. The stearic acid is isolated and then combined with sodium hydroxide in a saponification process to produce the soap ingredient called sodium stearate.
I couldn't find who created it, sorry.

<span>If the gasses participates in the reaction, and they under the same temperature and pressure, ratio of their volumes is equal to ratio of the moles of these gasses in the reaction.
N2 (g) + 3H2 (g)-------> 2NH3 (g)
from reaction 3 mol 2 mol
from the problem 4.5L x L
x=4.5*⅔=9/3=3 L<span>
