Identifying Organic Compounds, A colorless liquid A (C3H6O) was soluble in water and ether, and had a boiling point of 94-96 degrees Celsius. It decolorized a Br2-CH2Cl2 solution and gave a positive ceric nitrate test
Problem- For each pair below, write a balanced equation showing what happens when the two compounds are combined. If there is no reaction, show the solvated ions that result in the solution.
Write the complete name (prefix + unit) for each of the following numerical values:Part A 1×10-12g Spell out the complete name (prefix + unit).1×10-12g =1
A 1.00 g sample of D2O and H2O are reacted with CL2 and HCL and DCL are produced. Then they are diluted with H2O giving a volume of 1.00L. Then 25 mL of the solution are reacted with excess AgNO3 and 0.3800g AgCl precipitate formed.
