You probably already know the names of some molecules. Identify which compound (water, salt, carbon dioxide, or methane) corresp
2 answers:
Explanation:
Water has a formula which represents two hydrogen atoms are attached to one oxygen atom. Therefore, the formula of water is .
Salt is also known as sodium chloride. Its formula represents that one sodium atom is attached to one chlorine atom, therefore, its formula is NaCl.
Carbon dioxide has a formula which represents one carbon atom is attached to two oxygen atoms. Therefore, its formula is .
Methane has a formula which represents one carbon atom is attached to four hydrogen atoms. Therefore, its formula is .
Thus, we can conclude that is water,
is carbon dioxide, NaCl is salt, and
is methane.

If another proton gets added to the molecule there will be an increase in the atomic number and atomic mass by 1 unit and a new species will form.
here boron is taken which has an atomic number of 5 and atomic mass of 11 so when we add a proton to it, it will change into carbon having atomic number as 6 and atomic mass as 12.
The new species formed will be .
Answer:
C. pH values are different because the solution partially ionizes and the HCl solution ionizes 100 percent.
Explanation:
Strong acids are the acids which completely ionizes in the solution while weak acids are the acids which ionizes partially in the solution. They exists in equilibrium in the solution with their respective ions.
Thus, strong acids furnish greater concentration of protons as compared to weak acid when same concentration of both types are taken.
<u>Also, pH is the negative of the logarithm of the hydrogen ions. Thus, hydrogen ion concentration for both acids are different and thus pH will be different.</u>
