Answer:
A
Explanation:
This kind of bond is known as an ionic bond and is based on electrostatic forces between two charged molecules/atoms. To achieve stable configuration, sodium (2.8.1) transfers its valence electron to chlorine that also needs one electron to achieve stable configuration (2.8.8), and combine in an ionic bond.
Answer:
A solute is a substance that dissolves in a solvent to for a solution.Example; Sugar.
A solvent is a substance that dissolves a solute to form a solution.Example ;water.
A solution is a uniform mixture of a solute and a solvent.
aq means aqueous
In fiteration the residues are called filtrates but in crystalization the residues are called crystals .
Argon has 24 known isotopes.
Answer:
0.2 mol
Explanation:
Use the given values to find the molar mass. The molar mass is 40 g/mol.
23 + 16 + 1 = 40
Using the molar mass, convert grams to moles.
(8 g)/(40 g/mol) = 0.2 mol
You have 0.2 mol of sodium hydroxide.
