Answer:
The answer is: CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Explanation:
Boiling point refers to the temperature at which the pressure exerted by the surrounding on the liquid is equal to the vapor pressure of the liquid. The boiling point increases as the molar mass of the substance increases.
Since the molar mass increases in the order:
CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Therefore, the order of increasing boiling point:
CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Answer:
A
Explanation:
We are usually asked to close the valve of the gas cylinder in our various kitchens at home <u>due to the inflammable property of the Liquified Petroleum Gas.</u>
<em>Without closing the valve, the LPG would diffuse into our homes, and any form of spark would cause an explosion and lead to a fire. Lives and properties could be lost in the process.</em>
The correct option is A.
There are exactly (a). 10.0 and (b). 28.0
Answer:
Explanation:
The atomic number tell us the number of protons and neutrons in the nucleus of an atom. in other words ,each element has a unique number that identifies how many protons are in one atom of that element example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1.
Answer:
An elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electron.
Example:
The nucleus of a hydrogen atom or the H+ ion is an example of a proton. Regardless of the isotope, each atom of hydrogen has 1 proton; each helium atom contains 2 protons; each lithium atom contains 3 protons and so on.
