Answer:
the answer is actually c
Explanation:
Cold air is more denser than hot air because ,when cold air of some density, say 'd' is heated, the molecules/atoms move apart from each other and so the volume expands. i hope that helped you
The correct answer is option C, the concentration of the hydroxide ion is greater than the concentration of the hydronium ion
Reason -
An acidic solution has an ability to contribute hydrogen ion. Here a hydronium ion (H3O+) has an extra H+ ion along with a water molecule. Thus presence of hydronium ion in larger amount than the hydroxide ion would make the solution acidic. Thus, the concentration of hydroxide ion should be less than the hydronium ion to make the solution a basic solution.
Answer:
A. Species
Explanation:
Species is the most specific level of classification in taxonomy.
One mnemonic that can be used to remember the order of ranks is:
Dear King Philip Came Over For Good Soup
This stands for domain, kingdom, phylum, class, order, family, genus, species.
And, this is in order of the most broad to the most specific rank.
So, A is the correct answer.
