Answer: acid; acidic
Explanation:
You have a glass of pure water and add acidic lemon juice to it. This means that you are adding ACID to it, and the solution will become ACIDIC.
Pure water has a pH value of 7
Lemon juice has a pH value less than 7 i.e acidic
Therefore, addition of lemon juice to pure water will drop the latter pH from 7 to form a final solution that is ACIDIC.
Answer:
The answer to your question is: Arrhenius base
Explanation:
Arrhenius base ; an Arrhenius base is able to produce (OH-) in water, so Ca(OH)2 is an Arrhenius base.
Brønsted-Lowry base
. An Bronsted and Lowry base is able to accept a proton, Ca(OH)2 can do it.
Lewis base
this base is able to donate a pair of electrons, Ca(OH)2 does not have a pair of electrons to donate.
All of the above. This option is wrong only the first option is correct.
You can apply Charles' Law.
V1= 5.00 (L)
T1= 92.3 + 273 = 365.3 (K)
T2= -37 + 273 = 236 (K)
V2 = ? (L)
We have: V1/T1 = V2/T2
--> V2= (V1*T2)/T1 = (5*236)/365.3 = 3.23 (L)
