The empirical formula or simplest formula
gives the smallest whole-number ratio of
the atoms present in a compound.It gives the
relative number of atoms of each
element present in the compound.The ratio will be 3.72 : 21.28
Answer:
d. End product is that product with a ketone and carboxylic acid.
Explanation:
![{ \sf{NaBH_{4} : }}](https://tex.z-dn.net/?f=%7B%20%5Csf%7BNaBH_%7B4%7D%20%20%3A%20%7D%7D)
Sodium borohydride is a reducing agent, it reduces the ketone to a primary alcohol.
![{ \sf{H _{2} O \: and \: H {}^{ + } }}](https://tex.z-dn.net/?f=%7B%20%5Csf%7BH%20_%7B2%7D%20O%20%5C%3A%20%20and%20%5C%3A%20H%20%7B%7D%5E%7B%20%2B%20%7D%20%7D%7D)
Then acidified water is an oxidising mixture which reverses the reduction reaction.
Answer: C; it will also change from a gas to a liquid at 78°C while the gas loses energy.
Explanation:
Took the test. If it boils at 78°C, then that means it will be either a liquid turning into a gas, or a gas turning into a liquid. If the gas loses energy, that means it is being cooled, so if a gas loses energy at 78°C, it will become a liquid.
