Electrons - they are the particles that determine the chemical properties of an element
Answer:
evaporates
Explanation:
the heat from the sun causes it to evaporate
Answer
A. ethyl butanoate
Explanation:
Esters are known for their distinctive odors and are commonly used for food aroma and fragrances. The general formula of an ester is RCOOR'.
Esters are formed through reactions between an acid and an alcohol with the elimination of water.
Esters are named as if the alkyl chain from the alcohol is a substituent. No number is assigned to this alkyl chain. This is followed by the name of the parent chain from the carboxylic acid part of the ester with an –e remove and replaced with the ending –oate.
Hence, the name of the given ester is:
A. ethyl butanoate
Answer: Option (a) is correct.
Explanation:
It is known that electrons hold a negative charge. So, when the negative charge that is electrons are taken out an atom then the number of electrons become less in number as compared to the number of protons.
Hence, the atom attains a positive charge.
An isotope is formed when an atom shows same number of protons and different number of neutrons. So, when an atom loses 2 electrons there will be no change in the number of neutrons. Therefore, an isotope will not form.
Thus, it is concluded that when an atom with no charge loses two electrons, it becomes a positive ion.
