Based on our knowledge of strong and weak acids, we can confirm that the Ka value for acetic acid will be relatively low since it is a weak acid.
Acids can be strong or weak. This is determined by its <u><em>tendency to break apart into ions or stay together to form molecules.</em></u> Although somewhat counter-intuitive, strong acids are those that are most likely to break apart and therefore contain a <em><u>high number of </u></em><em><u>ions </u></em><em><u>within their solutions</u></em>.
Weak acids, on the other hand, are those that<em><u> tend to stay together in the form of </u></em><em><u>molecules </u></em><em><u>and therefore possess very </u></em><em><u>low ion counts </u></em><em><u>in their solutions.</u></em> The acid dissociation constant, Kₐ, is used to measure whether an acid is weak or strong and how much so. In the case of Acetic acid, the ka measurement will offer a low value, indicating a weak acid.

Answer:
The answer to your question is:
atomic number (Z): 6
mass number (A) : 13
Explanation:
Carbon has an atomic number of 6 and a mass number of 12,
Mass number = # protons + # neutrons
12 = 6 + # neutrons
#neutrons = 12 - 6 = 6
For the carbon isotope the atomic number does not change is still 6
13 = 6 + # neutrons
# neutrons = 13 - 6
# neutrons = 7
The addition of catalyst in a chemical reaction has 2 functions
1. if you add negative catalyst then the rate of chemical reaction decreases
2. if you add positive catalyst then the rate of chemical reaction increases.
Luster is how the surface of a mineral reflects light. It is not the same thing as color, so it crucial to distinguish luster from color. For example, a mineral described as “shiny yellow” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties.
