Answer:
Explanation:
A substance that produces an excess of hydroxide ion (-OH) in aqueous solution.
This is an arrhenius Base
According to the arrhenius theory, a base is a substance that combines with water to produce excess hydroxide ions, OH⁻ in an aqeous solution. Examples are :
- Sodium hydroxide NaOH
- Potassium hydroxide KOH
A substance that produces an excess of hydrogen ion (H+) in aqueous solution
This is an arrhenius Acid
An arrhenius acid is a substance that reacts with water to produce excess hydrogen ions in aqueous solutions.
Examples are;
- Hydrochloric acid HCl
- Hydroiodic acid HI
- Hydrobromic acid HBr
I did the math and i got 450 but i dont know if its right
V₁ = 420 mL
T₁ = 210 K
V₂ = ?
T₂ = 250 K
(Answer is 500 mL)
Answer: 23.6 grams HCl
Explanation:
The density 1.18g/mL just means that there is 1.18 grams of HCl per 1 mL of it.
So if you have 20 mL of it, it would just be 1.18 * 20 grams. This equals 23.6 grams of HCl.
It's just like if at your supermarket they sold apples for $1.00/lb. If you wanted 5 lbs, it would cost $5.00 ($1.00 * 5).
