Question 8
How many grams are in 3.9 moles of C3H5C13?
1
Answer:
Explanation:
To determine the number of grams in 3.9 moles of C3H5C13, we need to first determine the molar mass of C3H5C13. The molar mass of a substance is the mass of one mole of the substance, and it is calculated by adding up the atomic weights of all the atoms in the molecular formula.
In the case of C3H5C13, the molar mass is calculated as follows:
Molar mass of C3H5C13 = (3 x 12 g/mol) + (5 x 1 g/mol) + (13 x 35.5 g/mol) = 106.5 g/mol
Next, we need to multiply the molar mass by the number of moles to determine the number of grams:
3.9 moles x 106.5 g/mol = 421.05 g
Therefore, there are 421.05 grams in 3.9 moles of C3H5C13.
describe a situation where scientific knowledge is gained even though I hypothesis was not supported
Answer: The situation was Alexander Fleming made an experiment showing that the fungus produced a chemical that could kill bacteria. The scientific knowledge was based off Fleming's work, scientists produced the first antibitoic drugs.
It should reanalyze the data to determine whether their results contradicted your hypothesis if the experiment's findings did not support it. So shouldn't change the experiments, observations, or both in order to get results that support the theory.
What is hypothesis ?An assumption or concept is given as a hypothesis for the purpose of debating it and testing if it might be true.
If the facts continually contradict the hypothesis, it is obvious that the hypothesis is not a viable explanation for the phenomenon you are examining. The proposed explanation is disproved, and we now look for a fresh hypothesis to explain the experimental results.
If the results confirm the prediction, the hypothesis is supported. Results can be used to disprove the hypothesis if the prediction was not confirmed by the data. By monitoring data and creating a new hypothesis using the new facts, you might need to come up with new questions. Make a finding and a forecast.
Thus, It should reanalyze the data to determine whether their results contradicted your hypothesis if the experiment's findings did not support it.

One mole of carbon has a mass of 12 grams. One mole of sulfur has a mass of 32 grams. Why does one mole of each element not have the same mass?
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, one mole of each element not have the same mass as mole is directly proportional to the given mass.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically,
mole =given mass ÷ molar mass
For carbon For sulfur
number of moles of carbon= 1 number of moles of sulfur=1
mass of 1 mole of carbon=12g mass of 1 mole of sulfur=32 gram

P1 proton in the compound appear most upfield in the 1H NMR spectrum.
What is the main principle of NMR?
The foundation of NMR is the idea that all nuclei are electrically charged and that many of them have spins. Energy can go from the base energy to a higher energy level if an external magnetic field is provided.
The protons are most shielded ones among all the four types of protons as they experience +I effect from adjacent CH2 groups and are also situated far away from carbonyl group. therefore the -I effect is very less compared to the protons 2, 3 and 4. all these factors makes the proton 1 the most shielded and hence they will have very low delta value that is upfield.

moles of Br₂ = 0.086 mol
volume = 1.26 L

How much is 3040mmHg in atm? round to the nearest whole number
A pressure of 3040 mmHg is almost 4 atm.
Define ATM pressure?Atmospheric pressure (atm) is the unit of measurement corresponding to the mean atmospheric pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). Atmospheric pressure is most commonly approximated by the hydrostatic pressure caused by the weight of the air above the point of measurement. Atmospheric pressure decreases with altitude because the air mass above decreases as altitude increases. Since the atmosphere is thin relative to the Earth's radius (especially the dense atmospheric layers at low altitudes), gravitational acceleration as a function of altitude can be approximated as constant and contributes little to this decrease. Pressure is measured as force per unit area in SI units of Pascal (1 Pascal = 1 Newton per square meter, 1 N/m²). Atmospheric pressure at sea level is 760 cm Hg.
Given the,

amino acids with non-polar r-groups typically have which of the following characteristics in aqueous solution?
The correct answer is option (D) Amino acids with non-polar R-groups are hydrophobic and found buried within proteins.
What is Amino Acid?
The organic compounds known as amino acids are found in the human body. Amino acids can be found in the environment in a wide variety of forms.
Generally, the R groups or the side chains of the amino acids are classified into two classes – amino acids with polar side chains, and those with non-polar side chains. Non-polar amino acids are those amino acids having hydrocarbons R-group which are variable.
Non-polar side chains contain hydrocarbon, and at physiological pH (pH 7), they contain uncharged functional groups which are unable to participate in hydrogen bonding. e.g. isoleucine, leucine, Methionine, phenylalanine, alanine, cysteine, glycine, proline, tryptophan, tyrosine, and valine.
In aqueous solutions or in a polar environment protein-containing nonpolar side chains or R-group try to cluster in the interior of the protein due to hydrophobic effect because hydrophobicity of the nonpolar R-group serves as oil droplets which get clustered in an aqueous solution, and nonpolar side chain or R-groups found in the interior of the three-dimensional folded protein, while the proteins found in the hydrophobic environment, including those proteins located in membrane with nonpolar R-groups, are found on the outer surface of the protein, i.e. the nonpolar R-groups in the hydrophobic environment interact with the lipid environment and responsible for stabilizing the native conformation of a protein.
Conclusion – Proteins having nonpolar R-groups in aqueous does not participate in hydrogen bonds or ionic bonds, because the amino acids with nonpolar R-groups are hydrophobic, and do not bind with water, and nonpolar amino acids try to cluster in the interior or core of the protein because the nonpolar R-groups are hydrophobic.
Therefore, the correct answer is option (D) Amino acids with non-polar R-groups are hydrophobic and found buried within proteins.
