Answers
If the number of neutrons in the nucleus of the atom is 41, and the atomic number is 40, the mass number of that atom will be 81
What is mass number?Mass number is the sum of the number of protons which is the atomic number and neutrons of an atom.
It is represented using the letter ‘A.’
How to calculate the mass numberMass number = atomic number + neutrons
We have the atomic number as 40 and the number of neutrons as 41
The mass number = 40 + 41 = 81
Therefore, the mass number of the atom will be 81

Identify the one thing that you were most surprised by in the quiz. Explain
why.
Answers
Adhesion is the attraction of molecules of one kind for molecules of a different kind... water is adhesive because the water molecules are attracted to the straw and therefore adhere to it. Thus, adhesive forces are important for sustaining life. This is because of these forces, water can flow up from the roots to the tops of plants to feed the plant, allowing it to move against gravity through plant cells. Another example of why its important that water is adhesive is the movement of water to the tops of trees and the drainage of tears from tear ducts in the corners of your eyes. Or how water droplets stick to the end of the pine needles. These are all examples of adhesion.

How many protons, neutrons, and electrons are there in a neutral atom of 60 Co (cobalt- 60 )?
Answers
Cobalt-60 is comprised of 27 protons, 33 neutrons, and 27 electrons. Nuclear reactors are used to artificially create it.
What is cobalt- 60?A radioactive isotope containing cobalt with something like a half-life of 5.2713 centuries is called cobalt-60 (60Co). Nuclear reactors are used to artificially create it. Neutron irradiation of bulk material of the monoisotopic as well as mononuclidic cobalt element 59 Co is necessary for deliberate industrial manufacture.
The accidentally generated 60 Co in the latter instance (inside the absence of additional cobalt) is mostly the product of many phases involving neutron activation on iron isotopes inside the reactor. Cobalt-60 is comprised of 27 protons, 33 neutrons, and 27 electrons.
Therefore, cobalt-60 is comprised of 27 protons, 33 neutrons, and 27 electrons.

Answers
Considering the definition of empirical and molecular formula, the pair of compounds C₄H₁₀ and C₂H₅ has the same empirical formula.
The empirical formula is the simplest expression to represent a chemical compound and indicates the elements that are present and the minimum proportion in whole numbers that there are between their atoms. This formula is also known as the "minimum formula".
On the other side, the molecular formula is the chemical formula that indicates the number and type of different atoms present in the molecule. But unlike the chemical formula, it shows the actual number of atoms that make up a molecule.
In this case, you can observe that if you divide the amount of each element by 2 in compound C₄H₁₀, you get C₂H₅, which is the empirical formula of the compound.
Finally, the pair of compounds C₄H₁₀ and C₂H₅ has the same empirical formula.

Answers
The molecular formula shows the number of atoms present. The molecular formula of the gas is most likely ClO2.
In terms of gas density and molar mass, the ideal gas equation can be written in the form; PM = dRT
Where;
P = pressure of the gas
M = molar mass of the gas
d = density of the gas
R = molar gas constant
T = temperature of the gas
Making the molar mass of the gas the subject of the formula;
M = dRT/P
d = 2.875 g/L
R = 0.082 atmLmol-1K-1
T = 11°C + 273 = 284 K
P = 750.0 mm Hg or 0.99 atm
Substituting values;
M = 2.875 g/L × 0.082 atmLmol-1K-1 × 284 K/ 0.99 atm
M = 67.6 g/mol
The gas is most likely ClO2.

Using the standardized NaOH solution in the previous

Answers
Answer: Using the standardized NaOH solution in the previous question, the titration of 5.00 mL of vinegar required 42.25 mL of NaOH. What is the % of acetic acid in the vinegar? Concentration of NaOH from previous question= 0.0986 M. David C.
Explanation:
Please mark as brainliest for me.Thank you so much
The percentage of acetic acid in vinegar is 4.988 %., When the titration of 5.00 mL of vinegar required 42.25 mL of NaOH.
What is titration?Titration is defined as the process of chemical analysis method in which the amount of a sample's constituent is determined by mixing a precisely measured amount of the desired constituent with another material in a precise, known proportion. The equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, is to be detected by the titration.
According to the titration principle, V1=the volume of acetic acid and V1S1=V2S2
S1 is the acetic acid's strength
V1 = 42.25 ml * 0.0986 M / 5 ml = 0.833 M where V2 = Volume of NaOH S2 = Strength of NaOH
Hence, 1000 ml Vinegar contains 0.833 moles of acetic acid per 100 ml of vinegar (0.0833*60). G=4.998 grams of acetic acid
The amount of acetic acid in vinegar is 4.988%.
Thus, the percentage of acetic acid in vinegar is 4.988 %., When the titration of 5.00 mL of vinegar required 42.25 mL of NaOH.
