Answer:
2.41 * 10^24 atoms of carbon present in the products.
Explanation:
First, we need to find the moles of carbon in the products in order to find the number of atoms.
We see that in the chemical formula, carbon belongs to the compound known as glucose. To get the amount of moles of carbon, we need to divide my the amount of carbon within glucose (in grams) from the total amu ( or grams) of glucose to get the moles.
C6 = 72.066.
C6H12O6 = 180.156
72.066/180.156 = 0.4000199827 moles of Carbon within the Glucose compound
Now we will convert to atoms/molecules by multiplying the moles by avogadro's number..
0.4000199827 moles C * 6.022*[tex]10^{23}[/tex] = 2.408920336 *[tex]10^{24}[/tex] atoms of Carbon present in the products
*Note --> this can be estimated to 2.41 * [tex]10^{24}[/tex] atoms of Carbon

Suggest a possible mechanism for the acid catalyzed reaction of a typical ketohexose to give 5-hydroxymethylfurfural.
Answer:
See explanation
Explanation:
Taking the acid catalysed hydrolysis of fructose C6H12O6, the mechanism begins with the protonation of an -OH group as shown.
This is now followed by dehydration and formation of a keto-enol tautomer. The keto form is now dehydrated followed by the protonation of a second -OH group.
A second dehydration followed by deprotonation leads to the formation of 5-hydroxymethylfurfural.

Which reaction takes place in a nuclear fission reactor?
C+HN
2 Put He → Cm
OCO+ He-Cot 'n
o U+ nKr+Ba+3'n
Answer:
The reaction that takes place in a nuclear fission reactor is answer D.
Explanation:
Step-by-step explanation:
Nuclear fission reactions involves the process by which large atomic nuclei are bombarded with energetic particles and release of an enormous amount of nuclear energy, which mainly ends up as heat energy.
So now, consider the nuclear reaction from D, after the uranium nucleus absorbs the neutron its split into two smaller nuclei (often radioactive themselves), Krypton and Barium and releases more neutrons (or energy).

What is required to cause change in matter
Answer:
Adding or removing energy from matter causes a physical change as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). And removing energy from liquid water causes it to become ice (a solid). ... Most liquids contract as they freeze.

In an industrial process ethanol C2H60 burns with O2 to produce heat. Each mole of ethanol produces 8842 joules during the reaction.
C2H5OH (1) + 3 O2(g) 2 CO2(g) + 3 H2O(0) + 8842 Joules
How many Kilojoules are obtained from burning 982.6 g of ethanol?
Answer:
[tex]189kJ[/tex]
Explanation:
Hello!
In this case, since one mole of ethanol release 8,842 J per 1 mole of ethanol, we can write:
[tex]\frac{8,842J}{1molC_2H_6H}[/tex]
Thus, since we need the energy released by 982.6 g of ethanol, we compute the moles in such mass of fuel:
[tex]n=982.6g\frac{1mol}{46.08g} =21.3mol[/tex]
Therefore, the result is:
[tex]\frac{8,842J}{1mol}*21.3mol=188,545J[/tex]
Which in kJ is:

Why are a molecule's atoms as far away from each other as they can get?
A) Electronegativity differences force the atoms apart
B) The protons in the nuclei push the atoms apart
C) Forces between electron pairs push the atoms apart
D) Induced dipoles push the atoms away from each other
Answer:
the answer is a
Explanation:
an electron contains a negative charge and like charges repel each other. Hence, in a atom the force of repulsion between the atoms away from each other. As a result a molecules atoms are as far away from each others as they can get .
A molecule's atoms as far away from each other as they can get because "Forces between electron pairs push the atoms apart".
So, option C is correct one.
Why electrons repel each other?Since, an electron is negative charge species revolve around the nucleus of an atom. So, when two atoms come close to each other in molecules there is repulsion occurs between negative charge electron .

What is the final pressure of 1.00 mol of ammonia gas, initially at 1.00 atm, if the volume is:___________.
a. gradually decreased from 78.0 mL to 39.0 mL at constant temperature.
1) 2.00 atm
2) 1.00 atm
3) 0.50 atm
4) Not enough data
b. increased from 43.5 mL to 65.5 mL at constant temperature.
c. decreased by 40% at constant temperature.
Answer:
The correct answer is a = 2 atm, b = 0.66 atm, and c = 1.66 atm.
Explanation:
a. When the temperature is constant, the ideal gas equation, that is, PV = nRT becomes PV = constant, or P1V1 = P2V2
Based on the given information, the pressure of the gas is 1.00 atm, the V1 of the gas is 78 ml, and the V2 of the gas is 39 ml.
Now using the above formula we get,
P2 = (P1V1) / (V2)
P2 = 1 atm * 78 ml/39 ml
P2 = 2 atm.
b) Now the volume V1 is 43.5 ml, and the volume V2 is 65.5 ml at constant temperature, P1 is 1 atm. Now P2 will be,
P2 = (P1V1) / (V2)
P2 = 1 atm * 43.5 ml/65.5 ml
P2 = 0.66 atm
c) In the given case, when the volume is decreased by 40 percent, let us consider that the volume, V1 be 100 ml, and the volume V2 be 60 ml, the P1 is 1 atm, now the P2 will be,
P2 = (P1V1) / (V2)
P2 = 1 atm * 100 ml/60 ml
P2 = 1.66 atm.

You weighed out 0.020 g of your crude aspirin product in order to determine the amount of salicylic acid impurity. Following the procedure outlined in the manual, you dissolved the solid and diluted the solution to a final volume of 10.0 mL. If the absorbance of your sample solution was 1.07, what was the percent salicylic acid in your product?
a. 6.4%.
b. 10%.
c. 7.8%.
d. 92%.
e. none of the above.
Answer:
7.8%
Explanation:
Given that:
The initial mass amount of aspirin = 0.020g
The standard molar mass of aspirin = 240 g/mol
Thus, the number of moles = mass/molar mass
= 0.020/240
= 0.0000833 moles
Now, the molarity of aspirin in the solution(diluted) [tex]C_1[/tex] = [tex]\dfrac{8.33 \times 10^{-5}}{0.01}[/tex]
= [tex]= 8.33 \times 10^{-3} \ M[/tex] (provided the volume v = 0.01 L)
The absorbance of the sample solution A =1.07
The path length (b) = 1 cm
From the standard value of salicylic acid, the coefficient (e)= 139.322 /M/cm
Now; according to Beer's law, the concentration of aspirin is:
A = e×b×c
[tex]c = \dfrac{A}{eb}[/tex]
[tex]c = \dfrac{1.07}{139.322 \times 1}[/tex]
c = 0.00768 M
Finally, relating the concentration of the aspirin, the percentage of salicylic acid the product [tex]= \dfrac{0.00833-0.00768}{0.00833} \times 100[/tex]
= 7.8%

What is the degree of oxidation of a simple substance
Answer:
The oxidation state of a free element (uncombined element) is zero. For a simple (monoatomic) ion, the oxidation state is equal to the net charge on the ion. For example, Cl– has an oxidation state of -1. When present in most compounds, hydrogen has an oxidation state of +1 and oxygen an oxidation state of -2
