Answer:
Atom
Explanation:
The atom is the simplest unit of matter that has all the properties of an element. It is made up of 3 subatomic particles: protons, electrons and neutrons.
Knocking out the other choices, the cell is the basic unit of life. An electron is only part of an atom, which has its own properties, while a compound is a combination of two or more elements that are chemically bonded.
Answer:
The solution will be dilute
Explanation:
The concentration of a solution is defined as the ratio between an amount of solute (Glucose, in this case) and an amount of solvent (Water in this case).
As the student is adding some water (Solvent), the amount of solute per amount of solvent will decrease. That is, if the concentration decreases,
the solution will be dilute
Explanation:
i think the answer is....b
<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>

What is Electronic Configuration?
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics as well as quantum chemistry. For instance, the neon atom's electron configuration is 1s2 2s2 2p6, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells. According to electronic configurations, each electron moves independently within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants as well as configuration state functions are used to mathematically describe configurations.
