Answer:
A.) because they have delocalized electrons
Explanation:
This is right on edg. 2020
D = m / V
1 mL = 1 cm³
1.11 = m / 417
m = 1.11 x 417
m = 462.87 g
Answer:
A. Close the drying agent container whenever it is not in active use.
C. Wrap the lid of the drying agent container with tape for storage.
Explanation:
Drying agents also known as desiccants are used in pharmaceutical, food and other manufacturing to keep substances dry. These drying agents are anhydrous and hygroscopic. The right usage of these products requires that they are always stored in an air-tight container.
When they are to be removed from a container containing a solvent, they are to be separated by filtration or decanting.
Answer:
Complete combustion of 0.1mol of monocarboxylic acid requires V litres of O2 at dtc. and the reaction produces 0.3mol of CO2 and 0.2mol of H2O.
What is the value of V?
Explanation:
The balanced chemical equation of the reaction is

1mol. of acid reacts with 1mol of
and produce 2mol. of CO2 and 2mol. of H2O.
Given,
0.1mol of acid requires how many litres of oxygen at STP?
0.1mol of acid requires 0.1mol of oxygen.
Since, 1mol of oxygen at STP occupies 22.4L of volume.
Hence, the volume occupied by 0.1mol of oxygen is -- 2.24L
Answer is:
The value of V is 2.24L.
