The given reaction describes the decomposition of glucose into ethanol and carbon dioxide. This process is called fermentation. The reactant of this reaction is glucose.
What is fermentation ?Fermentation is the process of conversion of sugar molecule into other substance b the action of microbes such as yeast. In cellular respiration the glucose molecule is converting to carbon dioxide and water. Where as, in fermentation, the glucose is converting to carbon dioxide and ethanol.
The balanced chemical equation of the breaking of glucose into carbon dioxide and water is written as follows:
[tex]\rm C_{6}H_{12}O_{6} \rightarrow 2CO_{2} + 2C_{2}H_{5}OH.[/tex]
According to this reaction, one mole of glucose molecule gives 2 moles of carbon dioxide and 2 moles of ethanol. Hence, reactant in this reaction is glucose.

The question is incomplete; the complete question is;
Using a triple beam balance and a graduated cylinder, a student collected data on a sample of an element:
Mass of sample = 18.9 g
Volume of water = 30.0 mL
Volume of water and sample = 35.0 mL
Calculate the density of the sample using sig figs.
Answer:
3.8 g/mL
Explanation:
Mass of sample = 18.9 g
Volume of water = 30.0 mL
Volume of water and sample = 35.0 mL
Volume of the sample = 35.0 mL – 30.0 mL = 5.0 mL
D = m/v
D = 18.9 g / 5.0 mL =3.8 g/mL

A researcher takes a 10 mL sample of HCl from a bottle and titrates it with NaOH. It was found that 22.4 mL of 0.25 M NaOH were required to reach the equivalence point. What is the concentration of the HCl in original bottle?
Answer : The concentration of the HCl in original bottle is 0.56 M.
Explanation :
According to neutralization law:
[tex]M_1V_1=M_2V_2[/tex]
where,
[tex]M_1[/tex] = concentration of HCl
[tex]M_2[/tex] = concentration of NaOH
[tex]V_1[/tex] = volume of HCl
[tex]V_2[/tex] = volume of NaOH
Given:
[tex]M_1[/tex] = ?
[tex]M_2[/tex] = 0.25 M
[tex]V_1[/tex] = 10 mL
[tex]V_2[/tex] = 22.4 mL
Now put all the given values in the above formula, we get:
[tex]M_1\times 10mL=0.25M\times 22.4mL[/tex]
[tex]M_1=0.56M[/tex]
Therefore, the concentration of the HCl in original bottle is 0.56 M.

You are given a sulfuric acid solution of unknown concentration. You dispense 10.00 mL of the unknown solution into an Erlenmeyer flask and add 12.2 mL of distilled water and a drop of phenopthalein to the flask. You fill your buret with 0.103 M NaOH (aq) solution and begin the titration. During the titration you rinse the tip and the sides of the Erlenmeyer flask with 3.52 mL of distilled water. It requires 10.38 mL of your NaOH (aq) solution to reach the endpoint and a very faint pink color in the flask. What is the concentration of your sulfuric acid solution in M (Remember the balanced equation for this reaction)?
Answer:
"0.053457 M" of sulfuric acid.
Explanation:
The given values are:
[tex]V[/tex] = 10 mL solution
[tex]V_{added}[/tex] = 12.20 mL
[tex]V_{total}[/tex] = 22.20 mL
then,
M 0.103 M of NaOH,
[tex]V_{rinsed}[/tex] = experiment will not be affected
[tex]V_{total \ base}[/tex] = 10.38 mL
Now,
⇒ mol of NAOH = MV
= [tex]0.103\times 10.38[/tex]
= [tex]1.06914 \ m[/tex]
Whether Sulfuric acid, then
⇒ [tex]H_{2}SO_{4} + 2NaOH = Na_{2}SO_{4} + 2H_{2}O[/tex]
⇒ [tex]mol \ of \ acid =\frac{1}{2}\times \ mol \ of \ base[/tex]
⇒ [tex]1.06914 \ m \ mol \ of \ base = \frac{1}{2}\times 1.06914 = 0.53457 \ m \ mol \ of \ acid[/tex]
Before any dilution:
[tex]V_{sample} = 10 \ mL[/tex]
⇒ [tex]M \ acid = \frac{m \ mol}{V}[/tex]
[tex]=\frac{ 0.53457 }{10}[/tex]
[tex]=0.053457 \ M[/tex] (Sulfuric acid)

How many moles of C can be synthesized from 31.0 moles of Y and excess X?
D
Answer:
This problem is providing a chemical equation between two hypothetical elements, X and Y and asks for the molesof X that are needed to
produce 21.00 moles of D in excess Y. After the following work, the answer turns out to be 15.75 mol X:Mole ratios:In chemistry, one the most crucial branches is stoichiometry, which allows us to perform calculations with grams, moles and particles (atoms, molecules and ions). It is based on the concept of mole ratios, whereby the moles of a specific substance can be converted to moles of another one, say product to reactant, reactant to reactant, reactant to product and product to product.
Calculations:In such a way, since 21.00 moles of D are given, we need the mole ratio of D to X in order to get the answer, which according to the reaction is 3:4 based on their coefficients in the reaction. Hence, we calculate the required as follows:

The enthalpy of solution (∆H) of NaNO₃ is 20.4 kJ/mol. If 6.10 g NaNO₃ is dissolved in enough water to make a 100.0 mL solution, what is the change in temperature (°C) of the solution? (The specific heat capacity of the solution is 4.184 J/g･°C and the density of the solution is 1.02 g/mL)
The enthalpy of solution is the heat evolved or absorbed in solution. From the calculations performed, the enthalpy of solution is 3.2°C.
What is is heat of solution?The term heat of solution refers to the heat evolved or absorbed when a substance is dissolved in water.
Number of moles of NaNO3 = 6.10 g/85 g/mol = 0.07 moles
Heat absorbed = 20.4 kJ/mol * 0.07 moles = 1.43 kJ
Mass of solution = 1.02 g/mL * 100 mL = 102 g
Mass of system = 102 g + 6.10 g = 108.1 g
Heat capacity of solution = 4.184 J/g･°C
From;
H = mcdT
1.43 * 10^3 J = 108.1 g * 4.184 J/g･°C * dT
dT = 1.43 * 10^3 J/108.1 g * 4.184 J/g･°C
dT = 3.2°C

Identify the NMR term that corresponds to each description.
A) The end of the NMR spectrum close to the reference signal
B) The end of the NMR spectrum far from the reference signal
C) The appearance of multiple peaks for a single nucleus due to neighboring nuclei
D) The frequency at which a nucleus absorbs and resonates with a magnetic field
E) The area of a signal that corresponds to the number of nuclei at that frequency
Answer:
A- upfield
B- down field
C- splitting
D- chemical shift
E- integration
Explanation:
NMR is a spectroscopic technique commonly used to observe the magnetic fields around the nucleus of atoms in a compound under investigation.
A chemical shift is the difference in parts per million (ppm) between the resonance frequency of the observed protons in the compound under study and that of the tetramethylsilane (TMS) (the reference compound in NMR with a chemical shift of zero ppm because all protons in the compound are equivalent).
If signals appear close to the reference signal, the signals are said to appear upfield. If the signals appear far away from the reference, they are said to appear down field.
The presence of protons cause splitting of peaks to the magnitude of n+1. n is the number of neighboring protons. Splitting refers to the appearance of multiple peaks for a single nucleus due to neighboring nuclei.
The area of a signal that corresponds to the number of nuclei at that frequency is called the integration.
