the reaction between c6 h12o6 and o2 is represented by the balanced equation above. in an experiment, 0.30 mol of co2 was produced from the reaction of 0.05 mol of c6 h12o6 with excess o2 . the reaction was repeated at the same temperature and in the same container, but this time 0.60 mol of co2 was produced. which of the following must be true? a the initial amount of c6 h12o6 in the container must have been 0.10 mol b exactly 0.30 mol of c6 h12o6 must have reacted because c atoms were conserved. c exactly 0.40 mol of o2 must have reacted because the temperature and container volume are the same. d more than 0.60 mol of o2 must have reacted because it was present in excess
There had to have been 0.10 mol of C₆H₁₂O₆ in the container.
The above reaction clearly indicates that when 1 mol of C₆H₁₂O₆ and 2 mol of CO₂ are combined and O₂ is given in excess, this combination alone determines the development of a product. Therefore, C₆H₁₂O₆ is a limiting reactant and O₂ is an excess reactant in this reaction.
To make 1 mol of CO₂ from 0.05 mol of C₆H₁₂O₆, it takes 6 times as much C₆H₁₂O₆.
Now, 0.60 moles of CO₂ must be produced from 0.6 divided by 6 mol of reactant, which equals to
moles of C₆H₁₂O₆ = 0.6/6 = 0.1 mol
Therefore, the initial amount of C₆H₁₂O₆ in the container must have been 0.10 mol.

Can dew point be calculated?.
Using this Td = T - ((100 - RH)/5.) we can calculate the approximation of dew point temperature.
The dew factor is the temperature the air desires to be cooled to (at regular stress) in order to achieve a relative humidity (RH) of one hundred%. At this point the air can't maintain greater water inside the fuel shape.
In other words, it enables meteorologists discern out the amount of moisture inside the air. Once the dewpoint reaches the air temperature, the air can't keep any greater water vapor. it's at this point that fog, dew, or any kind of precipitation may additionally form.

In an experiment, light of a particular wavelength is incident on a metal surface, and electrons are emitted from the surface as a result. To produce electrons with higher kinetic energy per electron, the experimenter should do which of the following? 1. Increase the intensity and the wavelength of the light 2. Decrease the wavelength of the light 3. Decrease the intensity and increase the wavelength of the light 4. None of these would produce the desired result. 5. Increase the wavelength of the light
To produce electrons with higher kinetic energy per electron, the experimenter should increase the intensity and the wavelength of the light. In order to decrease the energy of each photon we need less frequency (ν) which means increased wavelength (λ) for the incoming light. The intensity has to be increased since it is directly proportional to the number of photoelectrons emitted.
What is Planck's equation?The energy of a particular photon can be calculated using Planck's equation:
E = hν
Here, E = Energy of a photon in joules (J)
h = Planck's constant (6.626×10⁻³⁴J⋅s)
ν = Frequency of light (Hz)
What is photoelectric effect?The photoelectric effect is a phenomena whereby electrons can be released from the surface of a metal when light strikes upon it. The electrons that are released from the metal are known as photoelectrons, and this process is also frequently called photoemission. The Kinetic energy (KE) of each photoelectron is given by KE = hν – Φ.
E (i.e, the total energy of the incoming photon) must be equal to the KE (i.e, the kinetic energy of the ejected electron) plus the energy required to eject the electron from the metal which is also called the work function (Φ).
E = KE + Φ
The value of Φ also changes depending on the metal. Writing the energy of the photon in terms of Planck's equation we get:
E = hν = KE + Φ
By rearranging this equation in terms of the kinetic energy of electrons, we get:
KE = hν – Φ

The ease with which a liquid evaporates depends on the strength of its intermolecular forces. A liquid with stronger intermolecular forces will have a _____ vapor pressure at a given temperature and thus a _____ boiling pointlower; higher
A liquid with stronger intermolecular forces will have a lower vapor pressure at a given temperature and thus a higher boiling point.
Intermolecular forces can be described as the forces that are present between the atoms of a molecule.
When the intermolecular forces are strong, it will not be easy to break these forces between atoms such that they begin to vaporize. As there will be lesser molecules breaking the bonds and vaporizing, the vapor pressure will be lower for molecules that have strong intermolecular forces.
As it will take high energy or heat to break the bonds in a molecule that has strong intermolecular forces, hence the boiling point in these liquids will be higher.

Question 11 Which of the following correctly lists species in order of increasing bond order? Be2 < C2 < N2
Be2 < C2 < N2 is correct order of bond order.
To verify the accuracy of any chemical structure, we use the octet rule, which stipulates that all atoms in a compound are expected to abide by. In the model of carbon IV oxide, every atom precisely satisfies the octet rule. Each atom in the molecule has eight electrons surrounding its valence shell. Given the overall number of bonds and electrons, as well as the fact that CO2 contains sixteen valence electrons, we can thus conclude that this structure is correct.

Is melting conduction convection or radiation?.
Melting is an example of convection.
Conduction can be understood as the process, which generally enables direct transfer of heat through the matter, this happens due to the difference in temperature, between adjacent parts of the object. It happens when the temperature of the molecules present in a substance increase, that is usually resulting in vigorous vibration.
Convection implies the form of heat transfer, by the real movement of matter, that usually occurs only in fluids. Fluid represents to any substance, whose molecules move freely from one place to another, such as liquid and also gases. It happens naturally or even forcefully.
The heat transfer mechanism in which there is no medium is required is called radiation. It refers to the movement of heat in waves, as it does not need any molecules to travel through.
Convection is a method of heat transfer that involves molecules within liquids such as gases and also liquid, It is best depicted by the melting ice, where snow melts as heat moves from the air to the ice. If we leave ice on the table, it will melt after sometime. The reason for this is that the surrounding area has become cold. Thus, cold transfer refers to the exchange of heat or also thermal energy between physical systems. When there is a difference in temperature between the two bodies, the ice is transferred from the colder body to the warmer body.

How does hydrogen get a full valence shell?.
By donating or sharing one electron with another atom or a molecule such as water.
By exchanging electrons, atoms form chemical bonds. This is determined by how many electrons make up an element's electron clouds. The valence number is equivalent to the number of accessible electrons in the outermost electron cloud. The electrons that are most suitable for forming chemical bonds are called valence electrons. These valence electrons can be shared with another atom to fill open energy levels in a covalent bond. In spite of the fact that this outermost level possesses eight potential electrons, the resulting chemical is an inert noble gas when all eight electrons are present. Atoms that don't have eight electrons in their outermost shells will join forces with other atoms to share the extra pair of electrons until they have eight.

Determining the exact yield of ATP for aerobic respiration is difficult due to number of reasons. In addition to generating ATP by oxidative phosphorylation in prokaryotic cells, proton motive force is also used for functions such as transporting materials across membranes and also rotating flagella.
Furthermore, the number of ATP generated per reduced NADH or FADH2 is not always a whole number. For every pair of electrons transported to the electron transport chain by a molecule of NADH, between 2 and 3 ATP are generated. For each pair of electrons transferred by FADH2, between 1 and 2 ATP are generated.
In eukaryotic cells, unlike in that of prokaryotes, NADH generated in the cytoplasm during glycolysis must be transported across the mitochondrial membrane before it can transfer electrons to the electron transport chain and this requires energy.

The balanced chemical equation for the fermentation of glucose, we can see that methanol and carbon dioxide are formed.
Fermentation, is generally a chemical process by which molecules such as glucose are broken down anaerobically or in the absence of water. More broadly we can understand that fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old.
Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of the animals. In yeast cells these are those yeast used for baking bread and also that are producing alcoholic beverages, glucose can be metabolized through cellular respiration as in other cells too.

What is the chemical equation for lactic acid?.
An organic acid is lactic acid. Its chemical formula is CH3CH(OH)COOH.
What results from the fermentation of lactic acid?Lactic acid (lactate) and NAD+ are produced during lactic acid fermentation. To enable glycolysis to continue and produce additional ATP, NAD+ cycles back.
Most sour milk products, including kumis, laban, yoghurt, kefir, and some cottage cheeses, contain lactic acid. Lactic acid causes the casein in fermented milk to coagulate, or "curdle." Additionally, lactic acid is in charge of giving sourdough bread its distinctive taste.
One of the organic acids is lactic acid. Lactic acid has the chemical formula C3H6O3. It is a chiral molecule as it contains two optical isomers, Levo and Dextro.

What is the electronegativity difference of of k and cl?
Answer:
[tex] \huge\fbox{2.34}[/tex]
Explanation:
Potassium (K): It is an alkali metal that lies in Group 1 of the periodic table, with an atomic number and electronegativity 19 and 0.82, respectively. There is only one electron in the outermost shell of potassium, so it prefers donating one electron to gain stability, and hence the tendency to pull or accept an electron is less in potassium.
Chlorine (Cl): It is an halogen that lies in group 17 of the periodic table, with an atomic number and electronegativity of 17 and 3.16, respectively. There is only one electron required to fulfil the outermost shell of chlorine, so it prefers accepting one electron, and hence the tendency to attract the electron is high for chlorine.
Electronegativity Difference of K and Cl = En of Cl- En of K
[tex]ED = 3.16 - 0.82[/tex]
[tex]ED = 2.34[/tex]
The electronegativity difference explains whether a compound is ionic or covalent.

[tex]\Large\bold{SOLUTION}[/tex]
The electronegativity difference between potassium (K) and chlorine (Cl) can be calculated by subtracting the electronegativity value of K from the electronegativity value of Cl.
The electronegativity of potassium is 0.82 and the electronegativity of chlorine is 3.16 (on the Pauling scale).
[tex]\sf Difference_{(Electronegativity)} = CI_{(Electronegativity)} - K_{(Electronegativity)}[/tex]
[tex]\sf Difference_{(Electronegativity)} = 3.16 - 0.82[/tex]
[tex]\sf Difference_{(Electronegativity)} = 2.34[/tex]
Therefore, the electronegativity difference between K and Cl is 2.34.
