Answer:
A pure substance has a constant composition and cannot be separated into simpler substances by physical means. There are two types of pure substances: elements and compounds. ... The ratio of the elements in a compound are always constant. (Water is always 11 % Hydrogen and 89 % oxygen).
Explanation:
Answer:
The answer to your question is: H₂CO₃ is a strong acid
Explanation:
HCl is a strong base. This option is wrong because HCl is a strong acid.
Water is a strong acid. Water is a neutral substance it is neither an acid nor a base.
HCO 3 is a strong acid. I can see clearly the molecule but if it were H₂CO₃ , it would be carbonic acid which is a strong acid, but if not, this aswer is wrong.
Ammonia is a strong base. This answer is incorrect, Ammonia is a weak base.
The IUPAC naming of compounds follow a set of rules. First, find the longest carbon chain and number them. As shown in the picture, the longest chain has 9 carbons. In the 3rd and 5th carbon atoms, there is a double bond for each. So, the parent chain is named as 3,5 - nonadiene, 'di' because there are two double bonds. Moreover, at the 5th carbon, there is a branching chain of two carbons (ethyl). Hence, its IUPAC name is: <span>(3e,5z)-5-ethyl-3,5-nonadiene.</span>
