Answer:
Explanation:
Hello,
In this case we use the Boyle's law which allows us to understand the volume-pressure behavior as an inversely proportional relationship:
Whereas we solve for as the required final pressure:
Best regards.
Answer:
True
Explanation:
The force gets weaker as you move further away from the nucleus. Therefore, the electrons in the outermost energy level have the most energy
Atomic number = protons
Protons = P Electrons = E P = E
Atomic mass = Neutrons + Protons
Atomic number = atomic mass = neutrons
P = E
AM - AN = N
Example:
Calcium = 20 Protons 20P = 20E
Atomic mass - atomic number = neutrons :)
Answer:
7 methyl 3 octyne is the answer option D
Answer:
0.205M
Explanation:
Molarity is an unit of concentration used in chemistry defined as the ratio between moles of solute (In this case, LiF) and liters of solution.
To solve this question, we must find the moles of LiF and the liters of the solution:
<em>Moles LiF -Molar mass: 25.939g/mol-:</em>
2.39g * (1mol / 25.939g) = 0.0921moles
<em>Liters solution:</em>
450mL * (1L / 1000mL) = 0.450L
Molarity is:
0.0921 moles / 0.450L =
<h3>0.205M</h3>
