Answer:
Explanation:
In one Ca(OH)₂ molecule, there are 5 atoms (1 Ca, 2 O and 2 H). This means that in 1.005x10²⁴ Ca(OH)₂ molecules, there are (5 * 1.005x10²⁴) 5.025x10²⁴ atoms.
To <u>convert molecules into moles</u>, we use <em>Avogadro's number</em>:
- 1.005x10²⁴ molecules *
= 1.6686 moles
Finally, we <u>convert moles into grams</u> using the <em>molar mass of Ca(OH)₂</em>:
- 1.6686 moles * 74.093 g/mol = 123.63 g
Scientists can bombard atomic nuclei with high-energy particles such as protons, neutrons, or alpha particles. Scientists synthesize a transuranium element by the artificial transmutation of a lighter element. ... It involves nuclear change, not chemical change. NOTE nuclear decay is a transmutation that happens naturally.
Answer:
fluorine atoms!!! can you please mark brainliest?
Answer:
The procedure you will use in this exercise exploits the difference in acidity and solubility just described.
(a) you will dissolve your unknown in ethyl acetate (an organic solvent). All of the possible compounds are soluble in ethyl acetate.
(b) you will extract with sodium bicarbonate to remove any carboxylic acid that is present.
(c) you will extract with sodium hydroxide to remove any phenol that is present.
(d) you will acidify both of the resulting aqueous solutions to cause any compounds that were extracted to precipitate.
