Answer:
Ali will need to either taste test or test the drinks on a ph scale. A neutral drink is water, as neutral has a ph of 7. The ph scale ranges from 1 to 14, going from acidic to basic. So if the drink has a ph less than 7, it is acidic, if its more, its basic.
Using the pH=-log[ hydrogen ions], assuming the pH of water is 7 then using the concept that kw=[ OH] [H+], then the [H+]= 10 power minus 7,since kw=10 to the power minus 14
Answer:
All the above
Explanation:
A. Electrical current conduction
Aqueous solutions of both strong and weak acids will conduct an electric current. Weak acids are poorer conductors because they produce fewer ions.
B. Reaction with magnesium
Both strong and weak acids will react with magnesium, although weak acids will react more slowly.
C. pH paper test
Both strong and weak acids will give a colour with pH test paper, although the colours will probably be different.
D. Litmus paper test
Both strong and weak acids will turn blue litmus red.
Answer:
Sunlight provide light energy.
Chlorophyll absorb light.
Explanation:
Sunlight provide light energy or give light energy from sun and it is use to produce glucose from carbondioxide and water which is also a source of energy.
Chlorophyll absorbs light energy and use it to convert carbondioxide and water into glucose and oxygen or it captures sun rays and produce glucose and water.
The mass of a neutron is 1.0086
