The reaction of hydrochloric acid and sodium hydroxide is a neutralization reaction wherein a mixture of acid and base produces salt, water, and energy in the form of heat. A neutralization reaction is exothermic, thus producing heat. This is why the beaker felt warm to the touch.
Answer:
Ethanol
Explanation :
The molecular structure of ethanol C2H5OH it is seen that there is a hydrogen atom attached to an oxygen atom, hence hydrogen bonding. This makes it has a greater surface tension than dimethyl ether.
Dimethy ether however has dipole moment in its structure. Dipole moments are said to be existent in a molecule when the charges are separated. This makes dimethyl ether have a lower surface tension. In the molecular tructure of dimethyl ether CH3OCH3) the oxygen atom is a negative atom in between two positive methyl group.
The only chemical elements that form stable homonuclear diatomic molecules<span> at standard temperature and pressure (STP) are the </span>gaseshydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), and chlorine (Cl2<span>). The answer must be one of the abovementioned element.
38.00/2 = 19 g/mol
Therefore, the gas is fluorine since it has an atomic weight 19 g/mol.</span>
