is this like a abcd question cause if it is than is C
Explanation:
Molar mass of Hg = 200.59g/mol.
Therefore Moles = Mass / Molar mass
= 100g / (200.59g/mol) = 0.499mol.
The answer is 5 hours 45 minutes
Answer:
The correct answer is :
1) Fehling's test,
2) Tollen's test
Explanation:
1. Fehling's Test is the test that confirms the presence of aldehydes by the Fehling solution that contain copper ion with tartrate ions in NaOH solution. The color of the solution is blue due to presence of copper ions. In this test aldehydes are confirmed by the reduction of the blue solution to a insoluble precipitate of copper oxide red color while in presence of ketones there is no change.
2. Tollen's test is also a test that help in identifying the presence of aldehyde as the Tollen's reagents oxidizes aldehydes where ketones as they lack hydrogen in them.
Thus, the correct answer is : 1) Fehling's test,
2) Tollen's test.
