Answer:
0.2 M is the concentration of the resulting solution
Explanation:
M is a unit for concentration which means mole of solute in 1L of solution.
According to the received information, we have 4 g in 500 mL of solution.
In 0.5L we have 4 g of solute
In 1L we have (1 .4)/0.5 = 8 g of solute
Let's convert the mass in mole
Mass / Molar mass = Mole
Molar mass NaOH = 40 g/m
8g / 40 g/m = 0.2M
Answer:
Nuclear fission is the process of splitting apart nuclei (usually large nuclei). When large nuclei, such as uranium-235, fissions, energy is released. So much energy is released that there is a measurable decrease in mass, from the mass-energy equivalence. This means that some of the mass is converted to energy.
Explanation:
Hey there!
Lithium has 3 protons.
Assuming this is a neutral atom, that means it will also have 3 electrons.
Atomic mass is the sum of protons and neutrons. We have 7 total protons and neutrons, and 3 electrons.
7 + 3 = 10
The total number of subatomic particles is 10.
Hope this helps!
they are different forms of energy movement.
