All of the aforementioned are incorrect if glycolysis produces two moles of for every mole of glucose.
D is the ideal choice.
What creates two molecules during glycolysis?Firstly, glycolysis yields two ATP, two NADH, and two pyruvate molecules. The aerobic catabolic breakdown of glucose known as glycolysis yields energy in the form of ATP, NADH, and pyruvate, which then enters the citric acid cycle to yield more energy.
From 2 moles of glucose, how many ATP are produced?76 ATP molecules can therefore be produced from two glucose molecules. Glycolysis. Two moles of ATP are created anaerobically for every mole of glucose.

1.9x10^23 atoms of sulfur to grams of sulfur
Answer:
see explanation and punch in the numbers yourself ( will be better for your test)
Explanation:
If you are given atoms you need to divide by Avogadro's number 6.022x10^23
then you will have moles of sulfur-- once you have moles multiply by the molar mass of sulfur to go from moles to grams
mm of sulfur is 32 g/mol
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, the grams of sulfur in 1.9x10²³ atoms of sulfur is 9.92g.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance.
Given number of atoms= 1.9x10²³atoms
we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number
mole =given number of atoms ÷ 6.022×10²³(Avogadro number)
Substituting the values
mole=1.9x10²³÷ 6.022×10²³
mole = 0.31 mole of sulfur
Mole = given mass÷ Molar mass
Molar mass of sulfur=32g/mol
mass of sulfur =0.31 mole ×32g/mol
mass of sulfur=9.92g
Therefore, the grams of sulfur in 1.9x10²³ atoms of sulfur is 9.92g.

Answer:
27 g
Explanation:
From the question,
n = Mv...................... Equation 1
Where n = number of mole of Al₂SO₄, M = Molarity of Al₂SO₄, v = Volume of the solution.
Given: M = 0.12 mol/L, v = 1.5 L.
Substitute these values into equation 1
n = 0.12×1.5
n = 0.18 mol
Also,
n = Mass(m)/Molar mass (m')
n = m/m'.
m = n×m'......................... Equation 2
Given: The molar mass of Al₂SO₄ = (27×2)+32+(16×4) = 150 g/mol
Substitute into equation 2
m = 0.18×150
m = 27 g
56.8 grams of glucose is dissolved in acetic acid. The boiling point of the acetic acid raises to 126.6°C. What is the molal concentration of the solution?
Answer:
Molal concentration of glucose = 2.64 m
Explanation:
The excersise can be solved by the formula for colligative property, elevation of boiling point.
ΔT = Kb . m . i
As glucose (C₆H₁₂O₆) is an organic compound, i = 1. (No ions generated)
ΔT = Boiling T° for solution - Boiling T° of pure solvent
Kb = Ebulloscopic constant.
We need data from acetic acid.
Boiling T° of pure solvent: 118.1°C
Kb = 3.22 °C/m
We replace data:
126.6°C - 118.1°C = 3.22°C/m . m . 1
(126.6°C - 118.1°C) / 3.22 m/°C = m
Molality = 2.64 mol/kg

Describe the composition of a molecular compound. What are two major characteristics of molecular compounds?
Answer:
A molecular compound is composed of two or more non metallic elements that are held together by covalent bonds.
The two major characteristics of molecular compounds are;
1.) They are held by covalent bonds
2.) They generally have poor conductivity
Explanation:
A molecular compound is one where two or more molecules come together to form a compound. Unlike ionic compounds that combine by the transfer of electrons, molecular compounds form by sharing electrons. The pairing of the electrons is what holds the molecules together and is known as covalent bonding.
A molecular compound has various characteristics, some of which are;
- Generally low melting and boiling points
- Soft solid forms
- Low enthalpy of fusion and vaporization.
But the two major characteristics of molecular compounds are;
1.) They are held together by covalent bonds.
The elements in a molecular compound share their electrons by having their atoms bond chemically to each other.
2.) They generally have poor conductivity
Molecular compounds do not conduct electricity and heat properly. Because they are formed by sharing electrons, they usually have no free electrons left to conduct electricity.

Which of the following answers below is the correctly balanced half-reaction for the reduction of the SO4 ^-2 ion in acid solution? The answer is C, but I don’t understand why. Thanks in advance :-)
Answer:
C
Explanation:
The oxidation number of Sulphur in SO4^2- is;
x + 4(-2) = -2
x - 8 = -2
x = -2 + 8
x = 6
Now,
the oxidation number of sulphur in H2SO3 is
2 (1) + x + 3(-2) = 0
2 + x -6 = 0
-4 + x = 0
x = 4
Hence, the oxidation number of sulphur changed from +6 to +4 which signifies gain of two electrons as shown in option C.

Unbalanced:
SeCl₆ + O₂ → SeO₂ + Cl₂
Count the atoms.
On the left side, we have 1 Se atom, 6 Cl atoms, and 2 O atoms.
On the right side, we have 1 Se atom, 2 O atoms, and 2 Cl atoms.
So everything is balanced except for Cl. To balance, we put a 3 coefficient in front of Cl₂.

when copper wires are made, a copper rod is pulled into a narrower wire. Explain how metallic bonding allows this to happen
Answer:
possibly because of the malleability of metals
Explanation:
In metallic bonding, electrons are delocalized and move freely among nuclei. When a force is exerted n the metal, the nuclei shift, but the bonds do not break, giving metals their characteristic malleability.

Adi loves the smell of lavender, so she decides to press a few petals of the flower until they release a few drops of oil. She wants to determine the molecular weight of the oily substance to try to identify the fragrance she likes so much. Her lab instructor tells her that her experiment will not work. Why do you think it will not work?
Answer:
See Explanation
Explanation:
What Adi failed to realize is that the oily substance that was obtained from lavender consists of a mixture of substances. It is not only the required fragrance that is present in the extract.
This experiment will not work because those other components in the mixture may be erroneously identified when they show up in the mass spectrum of the extract and may be mistaken for the fragrance in question.
Hence the experiment will not work because; if some kind of separation method is not used to identify other impurities in the oil, many other substances may be mistaken for the actual fragrance.
How many moles of KClO3 are needed to produce 480 grams of O2?
Answer:
2:3
You'd need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you'll always produce 3/2 times more moles of the latter.

In at least 4 complete sentences, describe the similarities and differences between Avogadro's Law and Charles' Law.
answer
Avogadro's law states that, at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles present. In other words, equal volumes of gases at the same pressure and temperature contain the same number of molecules - this is true regardless of their physical properties or chemical nature.

A 1.2 M solution of a weak base B is prepared. Using a pH meter, the pH is measured to be 11.82. Calculate the base ionization constant
Answer:
Kb = 3.64x10⁻⁵
Explanation:
First we calculate the pOH of the solution:
pOH = 14 - pHpOH = 2.18Then we calculate [OH⁻]:
pOH = -log[OH⁻][OH⁻] = [tex]10^{-pOH}[/tex][OH⁻] = 0.0066 MFor a weak base solution with a relatively high concentration, we can use the following formula:
[OH⁻] = [tex]\sqrt{Kb*C}[/tex]Where C is the concentration of the weak base solution (1.2 M in this case).
With the formula above we can calculate Kb:
0.0066 = [tex]\sqrt{Kb*1.2}[/tex]Kb = 3.64x10⁻⁵I have a Helium party balloon that can hold 3.0 liters of gas. If I blow up this balloon with 0.10 moles of oxygen gas at a pressure of 1.0 atmosphere, what is the temperature of the balloon?
