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]
Best regards!
Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis
The given question is incomplete. The complete question is:
Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis. Determine the mass of glucose (C6H1206) produced
Answer: 60.0 g of glucose
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
a) moles of [tex]CO_2[/tex]
[tex]\text{Number of moles}=\frac{88.0g}{44g/mol}=2.0moles[/tex]
b) moles of [tex]H_2O[/tex]
[tex]\text{Number of moles}=\frac{64.0g}{18g/mol}=3.5moles[/tex]
[tex]6CO_2+6H_2O\rightarrow C_{6}H_{12}O_6+6O_2[/tex]
According to stoichiometry :
6 moles of [tex]CO_2[/tex] require = 6 moles of [tex]H_2O[/tex]
Thus 2.0 moles of [tex]CO_2[/tex] require=[tex]\frac{6}{6}\times 2.0=2.0moles[/tex] of [tex]H_2O[/tex]
Thus [tex]CO_2[/tex] is the limiting reagent as it limits the formation of product.
As 6 moles of [tex]CO_2[/tex] give = 1 moles of glucose
Thus 2.0 moles of [tex]CO_2[/tex] give =[tex]\frac{1}{6}\times 2.0=0.33moles[/tex] of glucose
Mass of glucose = [tex]moles\times {\text {Molar mass}}=0.33moles\times 180g/mol=60g[/tex]
Thus 60.0 g of glucose will be produced from 88.0 g of carbon dioxide and 64.0 g of water
In green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis produces 60.0 g of glucose.
To calculate the moles, we use the equation:
Number of moles Given mass Molar mass a) moles ofNumber of moles = (88.0g)/(44g / mol) = 2.0mol*epsilonb) moles of H2ONumber of les = (64.0g)/(18g / mol) = 3.5molesAccording to stoichiometry6 moles of re = 6mol of H2OWhat is mole fraction ?Mole fraction is a unit of concentration, described to be same to the range of moles of a element divided via way of means of the entire range of moles of a solution.
Thus it is well explained.

Distance is the measure of how far or near an object is placed. It can be referred to as the length between the two points. The distance can be calculated by the formula, [tex]\rm Work = Force \times Distance.[/tex]
What are work and force?Work is the amount of force or energy required by the system to move the thing or the object from its original position to another. It is estimated in joules.
Force is the strength or the power required by the object to change its motion. It is calculated in Newtons.
The distance can be measured by using the work and the force applied by the object to move from initial to the final position as,
[tex]\rm Work = Force \times Distance[/tex]
Therefore, distance can be calculated by work and force.

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.

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.

What is the formula for tetracarbon difluorine octabromide?
Answer: The formula for tetracarbon difluorine octabromide is [tex]C_4F_2Br_8[/tex]
Explanation:
The naming of covalent compound is given by:
The less electronegative element is written first.
The more electronegative element is written second. Then a suffix is added with it. The suffix added is '-ide'.
If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on.
Hence, the correct formula for tetracarbon difluorine octabromide is [tex]C_4F_2Br_8[/tex]

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.

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
[tex]\text{Number of moles of }NH_3==\frac{50.0g}{17.00g/mol}=2.94moles[/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.
