Explanation:
The boy with the help of litmus paper can easily decide it as follows:
(i) The drink that would turn a red litmus to blue would surely be basic in nature.
(ii) The drink that turns a blue litmus to red is be acidic in nature.
(iii) The drink that would not be affected by both red and blue litmus would is neutral in nature.
The test can be done with help of phenolphthalein or the methyl orange these reagents also show different color in different medium.
Please be rightly informed that the formula for km/day is 1 kilometer per hour (kph) = 24 kilometer per day (km/day).
<h3>Fundamental quantities</h3>
These are quantities which forms the basic unit of measurement. The units of fundamental quantities are called fundamental units.
The three major fundamental quantities are:
Other fundamental quantities are:
- Temperature
- Amount of substance
- Magnetic flux
- Electric current
So therefore, the formula for km/day is 1 kilometer per hour (kph) = 24 kilometer per day (km/day).

Answer:
a. electrons are transferred from silver in AgCl (aq) to Cd (s)
Explanation:
In this reaction Ag is reduced:
While Cd is oxidized:
With those two semi-reactions we can see that there's a transfer of electrons from silver in AgCl(aq) to the solid cadmium.
For the record, given that Ag was reduced, Cd was the reducing agent. And because Cd was reduced, Ag was the oxidizing agent.
Answer:
There is no difference between the two.
Explanation:
They both show the same volume. But, adding decimal places shows the least count of the instrument used and is more acceptable when recording values in scientific experiments
