Answer:
C. Corrosive waste
Explanation:
Hydrochloric acid is formed when hydrogen chloride gas is dissolved in water. The gas is toxic when inhaled and dissolves very readily in water to form the acid.
Hydrochloric acid is a strong acid as it ionizes completely in aqueous solutions to produce chloride ions and hydronium ions.
The concentrated acid is very corrosive in that it dissolves many other substances. Therefore, great care must be taken when handling the concentrated form of the acid.
It poses an environmental hazard due to its corrosive nature. Also, in industries and science laboratories, concentrated hydrochloric acid can corrode metal pipes and should not be drained into pipes without first being diluted.
However, the acid is very important in many industrial as well as laboratory procedures.
Answer:
Explanation:
given volume =5.3 litres
as we know that 1 litre =1 dm3
therefore 5.3 litres =5.3 dm3
now moles =given mass /molar mass
so mass =moles*molar mass
in order to find mass of carbon we need to find moles
therefore moles=given volume/standard volume standard volume at STP is 22.4 dm3
moles= 5.3/22.4
moles=0.236=0.24
now mass of carbon dioxide =moles*molar mass
mass = 0.24*44
mass=10.56kg
Answer: The answer is D.
Explanation:
As the air rushes toward the center, it winds up moving in a curved path thanks to the Coriolis effect. This creates a circular spinning pattern as air travels from areas of high pressure to low pressure. That's why hurricanes originating in the northern hemisphere rotate counterclockwise.
Hope this helps!
