Na-24 and Na-23 have the same number of atoms=11, different neutrons(13 and 12),different mass number(24 and 23)
<h3>Further explanation
</h3>
The elements in nature have several types of isotopes
Isotopes have the same number of protons and having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
number of atoms = 11
mass number = 23
number of neutrons=23-11=12
number of atoms = 11
mass number = 24
number of neutrons=24-11=13
Answer:
The heart sends blood around your body. The blood provides your body with the oxygen and nutrients it needs. It also carries away waste. Your heart is sort of like a pump, or two pumps in one
Answer:
Gravity is acting upon every object on the earth, and it is pulling everything towards its center. But everything does not collapse to its center because the surface on which the object stands provides the reaction force upward (away from the center) and balances the weight of the object.
Molar mass of KMnO4= 158.0 g Use this number to convertgrams to moles. moles of KMnO4= 23.7 g KMnO4x (1 mol KMnO4/158 grams KMnO4) moles of KMnO4= 0.15 moles KMnO4 Now the liters of solution is needed. Keep in mind, this is the total volume of the solution, not the volume of solvent used to dissolve the solute.
