Answer: The molar concentration of acetic acid in the vinegar is 0.539 M.
Explanation:
The formula used is:
where,
and are the concentration and volume of base.
and are the concentration and volume of an acid.
Given:
Molar concentration of NaOH = 0.1798 M
Volume of NaOH = 30.01 mL
Volume of acetic acid = 10.0 mL
Now putting all the given values in the above formula, we get:
Thu, the molar concentration of acetic acid in the vinegar is 0.539 M.

Answer: Si (choice D)</h3>
This is the element Silicon.
=========================================================
Explanation:
First convert each percentage to its decimal form.
For example, 92.2297% converts to 0.922297 after moving the decimal point two spots to the left.
After doing that, multiply those decimal values with their respective atomic mass unit (amu) values.
- 27.9769 * 0.922297 = 25.8030109393
- 28.9765 * 0.046832 = 1.357027448
- 29.9738 * 0.030872 = 0.9253511536
Then we add up the results
25.8030109393 + 1.357027448 + 0.9253511536 = 28.0853895409
That rounds to about 28.085
Then look at the periodic table to see the atomic mass of Cobalt (Co), Aluminum (Al), Nickel (Ni) and Silicon (Si). The mass values listed in the periodic table are weighted averages of all the isotopes. The units for the mass are still in amu.
- Cobalt = 58.933
- Aluminum = 26.982
- Nickel = 58.693
- Silicon = 28.085
We have a match with silicon, showing that <u>choice D</u> is the final answer.
The theory of blending inheritance was used to describe an actual blending of our alleles, that together would form a new allele. For example, skin color and height would be the result of the blend of the parent's alleles.
This theory doesn't explain why some traits disapear or are discrete.
On the other hand, Mendel's experiments with seed colors explains it. He demonstrated that genes are inherited in pairs and that in hybrid organisms, dominant versions of that gene, could hide the presence of a recessive version of that same gene.
