Protons : positive charge , about same mass as neutrons , in the nucleus
neutrons : no charge , about the same mass as a proton , in the nucleus
electrons : negative charge , less mass than protons and neutrons , in orbitals outside of the nucleus
A hypothesis is an experimental question that can later be proven correct or incorrect by scientific evidence.
The answer is 200 for sure!!!!!
Answer:
The compound which are boh soluble in water and hexane is
B. Ethanol and 1-propanol
Explanation:
The compounds ethanol and 1-propanol are soluble in both hexane and water.
It is soluble in water as both consists of polar end due to hydrogen bonding present in the -OH functional group.
and both are soluble in hexane as they contain a non polar end and the alliphatic hydrocarbon chain in them.
The solubility of alcohols varies in increasing order as the hydrocarbon chain increases. And becaue of this it becomes more non polar.
Non polar properties decreases for branched molecules.
so, the correct option is ethanol and 1-propanol.
