B. New atoms are formed as products.
Answer:
What is the empirical formula of the compound?
Explanation:
When the relative masses of elements in a hydrocarbon are given, it is possible to use this information to obtain the empirical formula by dividing the given masses of each element by the relative atomic masses of the element. The lowest ratio is now used to divide through to obtain the empirical formula of the compound.
The empirical formula only shows that ratio of atoms of each element present in the compound. From the information provided, the empirical formula of the compound is CH2. Hence the answer.
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of sodium bicarbonate and acetic acid is given as:

Ionic form of the above equation follows:

As, sodium and acetate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:

Hence, the correct answer is Option C.
Answer: A) 1.0 x 10-10 M
Explanation: The pH is 4.0, and pOH + pH = 14, so pOH = 10. [OH-] = 10^-pOH, so for this drink, [OH-] = 10^-10 M, or 1.0 x 10^-10 M.
Given its small size and high polarizing power, lithium is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.
<h3>What is lithium?</h3>
Lithium is a metal and a member of group 1 in the periodic table. It is a very small ion hence it has a different chemistry from the rest of the members of the group.
Lithium is not part of any of the biomolecules because given its small size and high polarizing power, it is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.
