The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms. But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had (200. g) of ordinary table sugar, which chemists call sucrose, and which has the chemical formula C1,H2,0. Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to the correct number of significant digits?
Answers
Answer:
The maximum mass of water produced is \(m__{H_2O}} =116 \ g\)
Explanation:
From the question we are told that
The mass of sucrose is \(m_s = 200 \ g\)
The chemical formula for sucrose is \(C_{12} H_{22} O_{11}\)
The chemical equation for the dissociation of sucrose is
\(C_{12} H_{22}O_{4} \to 12C + 11H_2O\)
The number of moles of sucrose can be evaluated as
\(n = \frac{m}{Z}\)
Where Z is the molar mass of sucrose which has a constant value of
\(Z = 342 \ g/mol\)
So
\(n = \frac{200}{342}\)
\(n =0.585\)
From the chemical equation one mole of sucrose produces 11 moles of water so 0.585 moles of sucrose will produce x moles of water
Therefore
\(x = \frac{0.585 * 11}{1}\)
\(x = 6.433 \ moles\)
Now the mass of water produced is mathematically represented as
\(m__{H_2O}} = x * Z__{H_2O}\)
Where \(Z__{H_2O}\) is the molar mass of water with a constant values of \(Z__{H_2O}} = 18 \ g/mol\)
So
\(m__{H_2O}} = 6.43* 18\)
\(m__{H_2O}} =116 \ g\)

complexes can be classified based on number of unpaired electron as follows square planar strong field: 2 unpaired electrons, octahedral weak field: 4 unpaired electrons, tetrahedral strong field: 2 unpaired electrons, octahedral strong field: 0 unpaired electrons, tetrahedral weak field: 4 unpaired electrons, square planar weak field: 4 unpaired electrons.
In a coordination complex, the number of unpaired electrons in the metal ion depends on the strength of the ligand field and the orientation of the ligands. Strong field ligands have a higher affinity for the d orbitals and can more effectively stabilize them, leading to a lower number of unpaired electrons in the metal ion.
Weak field ligands have a lower affinity for the d orbitals and do not stabilize them as effectively, leading to a higher number of unpaired electrons in the metal ion. The number of unpaired electrons also depends on the orientation of the ligands, with an octahedron (6 ligands) and a tetrahedron (4 ligands) leading to different numbers of unpaired electrons.

The reaction between water and ammonium nitrate results in increase in a temperature.
Hence, Option C is the correct answer.
When ammonium nitrate is dipped in a beaker which contains the water, the beaker becomes cold because it is an endothermic reaction. The endothermic reaction is a reaction that it absorbs energy from the outside in the form of heat.
Thus we can say that hydrating ammonium nitrate is an endothermic reaction, because of that the beaker becomes cold.

c. loss of allosteric binding site for AMP in phosphofructokinase.
d. loss of regulatory binding site for ATP in phosphofructokinase.
1. Increase
2. decrease
3. No effect
Answers
Answer:
a. Decrease
b. Increase
c. Increase
d. No effect
Explanation:
Glycolysis is present in muscle cells which converts glucose to pyruvate, water and NADH. It produces two molecules of ATP. Cellular respiration produces more molecules of ATP from pyruvate in mitochondria. Glycolysis increases in pyruvate kinase.
a. Loss of binding site for fructose 1,6-bisphosphate in pyruvate kinase: Decrease
b. Loss of allosteric binding site for ATP in pyruvate kinase: No effect
c. Loss of allosteric binding site for AMP in phosphofructokinase: Increase
d. Loss of regulatory binding site for ATP in phosphofructokinase: Increase
A. An important substrate in the glycolysis pathway is fructose 1,6-bisphosphate. It stimulates pyruvate kinase, an essential enzyme in glycolysis. The amount of pyruvate kinase that is activated will decrease if the fructose 1,6-bisphosphate binding site in pyruvate kinase is eliminated. As a result the rate of glycolysis in the muscle cells will probably decrease.
B. The allosteric ATP binding site of pyruvate kinase controls how active the enzyme is. However, pyruvate kinase is not significantly regulated by ATP in muscle cells. Therefore, it is unlikely that deletion of the ATP-binding allosteric site in pyruvate kinase would have no effect on the rate of glycolysis in muscle cells.
C. The rate-limiting enzyme in glycolysis, phosphofructokinase, is activated from all forms by AMP. It increases the rate of glycolysis by stimulating the activity of phosphofructokinase. If the allosteric binding site for AMP is eliminated, phosphofructokinase activation will be reduced. As a result, the rate of glycolysis in muscle cells will decrease.
D. Phosphofructokinase is inhibited allosterically by ATP. It regulates the rate of glycolysis by a feedback mechanism. High ATP concentrations cause phosphofructokinase to bind to its regulatory site, limiting its activity and delaying glycolysis. If the regulatory binding site for ATP is eliminated, the inhibitory action of ATP on phosphofructokinase would be lost. As a result, muscle cells will glycolysis at a faster rate.

Which change to the ecosystem had the largest effect on the the population of trout in Wisconsin?
Answers
The largest effect on the population of trout in Wisconsin was caused by the introduction of non-native species into the ecosystem.
The introduction of non-native species into an ecosystem can cause a disruption in the food chain, leading to a decrease in the population of native species. In Wisconsin, the introduction of non-native species such as the brown trout and rainbow trout has had a significant impact on the population of native brook trout.
The non-native species compete with the native brook trout for food and habitat, which has led to a decrease in the brook trout population. This highlights the importance of preserving the natural balance of ecosystems and avoiding the introduction of non-native species.

The reaction 3H₂(g) + N₂(g) → 2NH3(g) has an enthalpy of reaction of -92.6 kJ/mol. If 1 g of hydrogen and 2 g of nitrogen are
reacted, how much heat is produced (kJ)?
Answers
The amount of heat energy produced when 1 g of hydrogen and 2 g of nitrogen are reacted, is -6.61 KJ
How do i determine the heat energy produced?First, we shall obtain the limiting reactant. Details below:
3H₂ + N₂ -> 2NH₃
Molar mass of N₂ = 28 g/molMass of N₂ from the balanced equation = 1 × 28 = 28 g Molar mass of H₂ = 2 g/molMass of H₂ from the balanced equation = 3 × 2 = 6 gFrom the balanced equation above,
28 g of N₂ reacted with 6 g of H₂
Therefore,
2 g of N₂ will react with = (2 × 6) / 28 = 0.43 g of H₂
We can see that only 0.43 g of H₂ is needed in the reaction.
Thus, the limiting reactant is N₂
Finally, we the amount of heat energy produced. Details below:
3H₂ + N₂ -> 2NH₃ ΔH = -92.6 KJ
Molar mass of N₂ = 28 g/molMass of N₂ from the balanced equation = 1 × 28 = 28 gFrom the balanced equation above,
When 28 grams of N₂ reacted, -92.6 KJ of heat energy were produced.
Therefore,
When 2 grams of N₂ will react to produce = (2 × -92.6) / 28 = -6.61 KJ
Thus the heat energy produced from the reaction is -6.61 KJ

Explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP.
Answers
The ideal gas law equation is: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.
To determine the mass of NaCl that reacted with F2 at 290 K and 1.5 atm, we can rearrange the equation as follows: n = PV/RT. Substituting in the values for P, V, R, and T, we get: n = (1.5 atm)(18.0 L)/(0.0821 atm*L/mol*K)(290 K) = 0.835 mol NaCl.
To determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP (standard temperature and pressure), we would use the same equation but with the values for P, V, R, and T corresponding to STP. At STP, P = 0.987 atm, V = 18 L, R = 0.0821 atm*L/mol*K, and T = 273 K. Therefore, n = (0.987 atm)(18 L)/(0.0821 atm*L/mol*K)(273 K) = 0.792 mol NaCl.
