I have this assignment for my chemistry class and my teacher is not helping me and my peers out at all. If you can't answer all the questions, I understand. It's just read stressing us all out and I was hoping to get some clarification here.

What series of steps are required for this conversion

Fill up the table.

Here is a graph of the molarity of acetonitrile (CH3CN) in a reaction vessel during a certain chemical reaction. Use this graph to answer the questions in the table below. 0.030- 0.025- 0.0215 0.020- y M 0.015. 0.010- 0.005 0 5 10 15 20 25 30 seconds Is CH3CN being created or destroyed by the chemical reaction? If CH3CN is being created or destroyed, what is the rate at which it is being created or destroyed 8 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If CH3CN is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 8 seconds of the reaction? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. X O created O destroyed neither created nor destroyed ☐ ☐ 1 ×10 □·□ olo 0 [

#10-12 Choose the letter of the correct answer.

-Explain the distillation test. -Explain the Bomb Calorimeter test. -Explain the viscosity test.

I need help with the last question. The one about on the same graph

Use the information below to answer questions 1- 3. PCI,(g) 2 PCI;(g) + Cl2(8) PCI,(g) decomposes into PCI,(g) and Cl,(8) according to the equation above. A pure sample of PCI,(g) is placed in a rigid, evacuated 1.00 L container. The initial pressure of the PCI5(g) is 1.00 atm. The temperature is held constant until the PCI,(g) reaches equilibrium with its decomposition products. The figures below show the initial and equilibrium conditions of the system. PCI5 Potal = 1.00 atm PCI5, PCI3, and CI, Prstal = 1.40 atm Figure 1: Initial Figure 2: Equilibrium As the reaction progresses toward equilibrium, the rate of the forward reaction (A) increases until it becomes the same as the reverse reaction rate at equilibrium (B) stays constant before and after equilibrium is reached (C) decreases to become a constant nonzero rate at equilibrium (D) decreases to become zero at equilibrium If the decomposition reaction were to go to completion, the total pressure in the container would be (A) 1.4…

Answer With Work Shown Please . 1. CaO + H2O → Ca(OH)2 If you start with 2400 g of CaO, add excess water, and produce 2060 g of Ca(OH)2, what is the percent yield of the reaction? 2.Draw the Lewis dot structure of SiCl4 then determine if the molecule has polar bonds and if it is a polar or non-polar molecule. 3.If you have an unknown quantity of gas at a pressure of 1.2 atm, a volume of 31 liters, and a temperature of 870C, how many moles of gas do I have? R=0.0821 L*atm/K*mol

Use the data table to answer those questions

I Review | Constants | Periodic Table When water is in the liquid state, some of the water molecules will have enough kinetic energy to escape The table here shows the vapor pressure of water at different temperatures. Use this table to answer the following questions. Vapor Temperature (°C) from the surface of the water in the form of water pressure vapor (gas). The pressure resulting from this gas is called the vapor pressure. If the temperature gets high enough, the vapor pressure will be the same as the atmospheric pressure. At this point, the liquid will boil. (mmHg) 0.0 10.0 20.0 18 30.0 32 37.0 47 40.0 55 50.0 93 60.0 149 70.0 234 80.0 355 90.0 528 100. 760. Part A You are in a mountain range with atmospheric air pressure of 520 mmHg, and you wish to boil some eggs. What is the approximate boiling point of the water at this air pressure? Express your answer as an integer and include the appropriate units.

They are all part of one question. Ethanol, C2H6O, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The heat of combustion of ethanol is 326.7 kcal/mol.The heat of combustion of 2-methylhexane, C7H16, is 1.150×103 kcal/mol. How much energy is released during the complete combustion of 495 grams of 2-methylhexane ? ______kcalAssuming the same efficiency, would 495 grams of ethanol provide more, less, or the same amount of energy as 495 grams of 2-methylhexane?   Hydrocarbons, compounds containing only carbon and hydrogen, are important in fuels.The heat of combustion of cyclohexane, C6H12, is 936.8 kcal/mol.Write a balanced equation for the complete combustion of cyclohexane.   +       +   How much energy is released during the complete combustion of 364 grams of cyclohexane ? _______kcal   Combustion…

10. A student analyzed a limestone sample but forgot to dry it. He found 31.20% CaO, whereas the correct value was 31.60. If the error was caused by the failure to dry the sample, what percentage moisture did the sample contain?

Identify the missing organic reactant in the following reaction: OH + X H+ HO. H+ Note: This chemical equation only focuses on the important organic molecules in the reaction. Additional inorganic or small-molecule reactants or products (like H₂O) are not shown. In the drawing area below, draw the skeletal ("line") structure of the missing organic reactant X. Click and drag to start drawing a structure.
