Answer:
Hydrocarbon being non polar are soluble only in non polar solvent.
Explanation:
Hydrocarbon molecules either have very little polarity or they do not have polarity at all, this is because of absence of electro-negative atoms in their molecular structure. Due to this their solubility is also affected. The solubility of a compound depends on its polarity as it can dissolve in a polar solvent only when it is polar or else they are soluble in non-polar solvent
CH3NH2 + HOH ==> CH3NH3^+ + OH^-Which molecule/ion accepts a proton. That is the base. Which molecule/ion donates a proton. That is the acid.
A stable subatomic particle known by the symbol for "proton"
e elementary charge, p, H+, or 1H+ having a positive electric charge. Its mass is 1,836 times greater than an electron's mass and just a little bit less than that of a neutron (the proton–electron mass ratio). "Nucleons" refers to protons and neutrons together, each of which has a mass of roughly one atomic mass unit (particles present in atomic nuclei).
Each atom. has a nucleus. that contains one or more protons. In order to keep the atomic electrons bound, they offer the central attractive electrostatic force. An element's defining characteristic, known as the atomic number, is the number of protons in the nucleus (represented by the symbol Z)

Answer : The height of the column in a barometer is, 10.3 m
Explanation :
To calculate the height of the column in a barometer we are using formula as:
where,
P = external pressure =
Conversion used :
h = height of the column in a barometer = ?
= density of water =
Conversion used :
g = constant of gravity =
Now put all the given values in the above formula, we get:
Therefore, the height of the column in a barometer is, 10.3 m
