Answer:
0.57 moles of carbon dioxide are required to produce 0.095 moles of glucose
Note: The question is not complete. The complete question is given below:
Green plants use light from the Sun to drive photosynthesis, a chemical reaction in which liquid water and carbon dioxide gas form aqueous glucose C6H12O6 and oxygen O2 gas. Calculate the moles of carbon dioxide needed to produce 0.095 mol of glucose. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits
Explanation:
Photosynthesis is a chemical reaction in which liquid water and carbon dioxide gas chemically react to form the simple sugar glucose in aqueous form and oxygen gas using energy derived from sunlight. The balanced equation of photosynthesis is given below:
6 CO₂ + 6 H₂O ----> C₆H₁₂O₆ + 6 O₂
From the equation above, 6moles of carbon dioxide gas, CO₂ reacts with 6 moles of water molecules to produce 1 mole of glucose and 6 moles of oxygen gas. Thus, 6 moles of carbon dioxide are required to produce 1 mole of glucose.
0.095 moles of glucose will require 0.095 moles of glucose * 6 moles of CO₂/ 1 mole of glucose
Moles of CO₂ required = 0.57 moles of CO₂
Nickel carbonyl decomposes to form nickel and carbon monoxide, like this:
Ni(CO)4(g) → Ni(s)+ 4CO(g)
At a certain temperature, a chemist finds that a 2.6 L reaction vessel containing a mixture of nickel carbonyl, nickel, and carbon monoxide at equilibrium has the following composition:
compound amount
Ni(CO)4 0.597g
Ni 12.7g
CO 1.98g
Required:
Calculate the value of the equilibrium constant for this reaction.
Answer:
[tex]K=4.07x10^{-4}[/tex]
Explanation:
Hello!
In this case, according to the given chemical reaction, it is possible to set up the equilibrium expression as shown below:
[tex]K=\frac{[CO]^4}{[Ni(CO)_4]}[/tex]
Since the nickel product is solid and is not included. It means that the concentrations at equilibrium of CO and Ni(CO)₄ are:
[tex][CO]_{EQ}=\frac{1.98g}{28.01g/mol} *\frac{1}{2.6L}=0.0272M[/tex]
[tex][Ni(CO)_4]_{EQ}=\frac{0.597g}{170.73g/mol} *\frac{1}{2.6L}=0.001345M[/tex]
Thus, there equilibrium constant for the reaction turns out to be:
[tex]K=\frac{(0.0272)^4}{[(0.001345)}\\\\K=4.07x10^{-4}[/tex]

When a solution of cesium chloride (CsCl) is subjected to high-speed centrifugation, a stable density gradient is formed. Meselson and Stahl found that when cell contents were subjected to centrifugation with a CsCl solution, a band of DNA formed at the CsCl density that matched the density of the DNA. This technique is called density-gradient centrifugation.
a. True
b. False
Answer:
True
Explanation:
Messelson and strahl explain the semiconservative existence of DNA replication by using CsCl gradient centrifugation. The hardest would go and rest at the base of the test tube, while the lightest would be at the top, the lightest would find a position between the heavy and the lightest. When the heavy tube is centralized, from a pool of light, bulky and moderate DNA.
This technique is called density-gradient centrifugation. Hence, the given statement is true.
The light and dark circles in the picture represent different types of atoms. Which picture best represents a pure compound?
The third picture has only one type of combination of atoms so it represents a pure compound. Therefore, option (c) is correct.
What is a pure compound?A pure compound is a compound that contains two or more elements combined chemically in a fixed ratio. These compounds can be broken down into separate or simple elements by chemical methods.
A pure compound is formed when elements are joined together by chemical bonds. Compounds such as water, crystals, and baking soda as pure.
Water is a compound formed by the combination of oxygen and hydrogen in a fixed ratio. A pure substance is a substance that has only one kind of atom or molecule having a constant composition.
The first picture represents pure substance and the 2nd and 4th pictures represent mixed compounds. Therefore, the third picture represents a pure compound.

Answer:
[tex]\mathbf{a \ strong \ base \ such \ as\ LiOH \ or \ NaOH.}[/tex]
Explanation:
In the condensation reactions of carbonyl compounds, it is essential to establish the order of events in advance to minimize or suppress the possibilities of self-condensation and the occurrence of cross-condensation, which unfortunately are an obvious threat in these reactions.
Self-condensation:
Any carbonyl compound that has one or more alpha hydrogens, on the carbons adjacent to the carbonyl group, runs the risk of undergoing a self-condensation reaction if the corresponding rigor is not carried out.
Cross-condensation:
Ideally, in the condensation reactions of carbonyl compounds, one of the reacting molecules should quickly enolise, while the other preferably should not have Hα, to ensure that no other by-products are formed.

Calculate the precise Molar Mass of NH3 and calculate the moles in 50.0
grams.
Answer: Molar mass of [tex]NH_3[/tex] is 17.00 g and moles in 50.0 grams is 2.94.
Explanation:
Molar mass is defined as the mass in grams of 1 mole of a substance.
S.I Unit of Molar mass is gram per mole and it is represented as g/mol.
Atomic Mass of Nitrogen (N) = 14.00 g
Atomic Mass of Hydrogen (H) = 1.00 g
Molar mass of [tex]NH_3[/tex] = 1(14.00)+3(1.00) g = 17.00 g
According to avogadro's law, 1 mole of every substance contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles and weigh equal to its molecular mass.

Strawberries contain about 15 wt% solids and 85 wt% water. To make strawberry jam, crushed strawberries and sugar are mixed in a 45:55 mass ratio, and the mixture is heated to evaporate water until the residue contains one-third water by mass.
a) Draw and label a flowchart of this process.
b) Do the degree-of-freedom analysis and show that the system has zero degrees of freedom (i.e., the number of unknown process variables equals the number of equations relating them). If you have too many unknowns, think about what you might have forgotten to do.
c) Calculate how many pounds of strawberries are needed to make a pound of jam.
d) Making a pound of jam is something you could accomplish in your own kitchen (or maybe even a dorm room). However, a typical manufacturing line for jam might produce 1500 \mathrm{lb}_{\mathrm{m}} / \mathrm{h}. List technical and economic factors you would have to take into account as you scaled up this process from your kitchen to a commercial operation.
Answer:
A. The flow diagram is in the attachment
B. Degree of freedom = 0
C. 0.486
D. Energy, power, cost of production
Explanation:
1/3 of water = 0.3333
Sugar = 1-1/3 = 2/3
B.) 45/55 = 9/11 when divided by 5
m1/m2 = 9/11
Cross multiply and make m1 subject of the formula
m1/m2 = 0.818
m1 = 0.818m2 ----1
0.15m1 + m2 = 1 x 0.667
0.15m1 + m2 = 0.667
0.15(0.818m2) = 0.667
1.1227m2 = 0.667
M2 = 0.5941
We put value of m2 in equation 1
M1 = 0.818 x 0.5941
M1 = 0.486
So 0.486 pound of strawberry is what we need in order to make 1 pound of jam.
D. We need great heat for water evaporation
The technical and economic factors would be
1. Energy which is power consumption
2. Cost of production for equipments and materials
3. Power
4. And hazards
Ammonium chloride is produced in the thermochemical equation NH3 (g) + HCl (g) → NH4Cl (s) ΔH = –176 kJ.
How many moles of NH4Cl have been produced if the change in enthalpy is –528 kJ?
Answer:
3 moles of NH₄Cl
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
NH₃(g) + HCl(g) → NH₄Cl(s) ΔH = –176 kJ
From the balanced equation above,
1 mole of NH₄Cl where obtained when the change in enthalphy (ΔH) was –176 kJ.
Finally, we shall determine the number of mole of NH₄Cl produced when the change in enthalphy (ΔH) is –528 kJ. This can be obtained as follow:
From the balanced equation above,
1 mole of NH₄Cl where obtained when the change in enthalphy (ΔH) was –176 kJ.
Therefore, Xmol of NH₄Cl will be obtained when the change in enthalphy (ΔH) is –528 kJ i.e
Xmol of NH₄Cl = –528 / –176
Xmol of NH₄Cl = 3 moles
Thus, 3 moles of NH₄Cl where obtained from the reaction.
