To
determine the empirical formula of the compound given, we need to determine the ratio of each element in the compound. To do that we assume to have 100 grams sample
of the compound with the given composition. Then, we calculate for the number
of moles of each element. We do as follows:<span>
mass moles
C 56.79 4.73
H 6.56 6.50
O 28.37 1.77
N 8.28 0.59
Dividing the number of moles of each element with
the smallest value, we will have the empirical formula:
</span> moles ratio
C 4.73 / 0.59 8
H 6.50 / 0.59 11
O 1.77 / 0.59 3
N 0.59 / 0.59 1<span>

The empirical formula would be C8H11O3N.</span>
Answer:
if the pH of a solution is 2.0 that means the solution would be acidic.

Answer: Option (c) is the correct answer.
Explanation:
Temperature is used as for measuring the average kinetic energy present in a substance or object.
The internal kinetic energy obtained by the molecules of an object is known as thermal energy.
Hence, temperature measures the thermal energy of an object.
Whereas when this thermal energy flows from a hotter object to a cooler object which are placed adjacent to each other then it is known that heat is flowing.
Thus, we can conclude that heat differ from temperature as temperature measures thermal energy, and heat is the flow of thermal energy.
