Explanation:
Strontium atomic number = 38
Electronic configuration is
As orbital is valence orbital in strontium, the outer electrons exists in that orbital only.
The law of multiple proportions is..
Different compounds made of same element have different proportions by mass of those elements.
Answer:
41.66 mL of 12.0 M sulfuric acid are needed.
Explanation:
Concentration of sulfuric acid solution taken =
Volume of the 12.0 M Solution =
Concentration of required solution =
Volume of required 1.00 M solution =
(Dilution)
41.66 mL of 12.0 M sulfuric acid are needed.
The freezing point and the boiling point of a solvent when a non-volatile solute is dissolved in it decrease and increase respectively.
Electrons are added to the same principal energy level.
