Answer:
Reaction of water with K₂O produce base.
Explanation:
Reaction of water with K₂O:
K₂O + H₂O → 2KOH
when potassium oxide react with water it produces potassium hydroxide which is base.
Reaction of water with carbondioxide:
When carbondioxide react with water it produces carbonic acid.
CO₂ + H₂O → H₂CO
Carbonic acid is a weak acid and dissociate to gives H⁺ ions. It is aslightly acidic solution and convert into hydrocarbonate ions.
H₂CO₃ → H⁺ + HCO⁻₃
HCO⁻₃ → H⁺ + CO₃⁻²
Reaction of water with NO₂:
3NO₂ + H₂O → 2HNO₃ + NO
Nitrogen dioxide react with water and produce nitric acid and nitrogen monoxide.
Reaction of water with SO₂:
SO₂ + H₂O → H₂SO₃
When sulfur dioxide react with water it gives sulfurous acid.
Answer:
0.447 pounds
Explanation:
The density of Mercury in grams/mL is 13.55 - I multiplied that by the volume and got approximately 203.25 grams, I then turned it into Kilograms and multiplied by 2.2 lbs / kg.

Answer:
Mass of liquid unknown liquid = 10.4 g
Explanation:
Volume of liquid = 15 mL
Mass of liquid + graduated cylinder = 55.2 g
Mass of graduated cylinder = 44.8 g
Mass of unknown liquid = ?
Solution:
Mass of unknown liquid is calculated by subtracting the graduated cylinder mass from combined mass of liquid and graduated cylinder.
Mass of liquid = (Mass of liquid + graduated cylinder) - (Mass of graduated cylinder )
Mass of liquid = 55.2 g - 44.8 g
Mass of liquid = 10.4 g
So the mass of unknown liquid is 10.4 g.
