<span>Hey Jose! Thanks for asking a question here on Brainly.
⚪ Potassium
</span><span>⚪ Magnesium
</span><span>⚪ Sodium (aka Na)
</span><span>⚪ Lithium (aka Li)
These are all atoms that are likely to lose electrons in order to form cations. Hope this helps. -UF aka Nadia</span>
Answer:
:)
Explanation:
If we subtract the atomic number from the atomic mass: atomic mass - atomic number = number of protons + number of neutrons - number of protons. Thus we get the number of neutrons present in an atom when we subtract the atomic number from the atomic mass.
Answer is: near equivalence point indicator should change color, so we must pick indicator who changes color near pH of equivalence point.
Equivalence point is
the point which there is stoichiometrically equivalent amounts of acid and
base. <span>
<span>Chemist can draw pH curve (graph
showing the change in pH of a solution, which is being titrated) for
titration and determine equivalence point.</span></span>
Answer:
Atoms
Explanation:
Elements are the chemical combinations of two or more atoms of the same kind
I think you were doing it right. Just find something in your kitchen and google the chemical formula. And from that you can see the elements in it. For example:
Salt, NaCl, Sodium and Chlorine.
Baking Soda, NaHCO3, Sodium, Hydrogen, Carbon and Oxygen.
Vinegar, CH3COOH, Carbon, Hydrogen and Oxygen
