Answer:
18.01528
Explanation:
find this by adding the molecular masses of two hydrogen atoms and oxygen atom
Answer:
Ca(OH)₂(aq) ⟶Ca²⁺(aq) +2OH⁻(aq)
Explanation:
An Arrhenius base is a substance that dissociates in water to form hydroxide ions.
Ca(OH)₂(aq) ⟶Ca²⁺(aq) +2OH⁻(aq)
Calcium hydroxide dissociates completely in water to form hydroxide ions, so Ca(OH)₂ is a strong Arrhenius base.
Plasma's that reach a temperature equal to their surroundings
someone already asked this question by the way you should search it next time so you don't waste any points : )
Answer:
If you have a solution, you multiply the molarity by the volume in litres. There are two steps: Multiply the volume by the density to get the mass. Divide the mass by the molar mass to get the number of moles.
