Answers

117.3 grams of hydrogen gas is produced in the reaction

What is Graduated cylinders?

Graduated cylinders are long, slender vessels used for measuring the volumes of liquids. They are not intended for mixing, stirring, heating, or weighing. Graduated cylinders commonly range in size from 5 mL to 500 mL. Some can even hold volumes of more than a liter.

Density - density is the mass of a material substance per unit volume. d = M/V, where d is density, M is mass, and V is volume, is the formula for density. Grams per cubic centimetre are a typical unit of measurement for density.

2Al + 6 HCl = 2AlCl₃ + 3H₂

Density = mass / volume

2.702 g/mL = m / 5.50 mL

m = 14.861 g

mol Al = mass / molar mass

= 14.861 g / 26.98 g/mol

= 0.551 mol

So number of mol of aluminium nitrate formed will also be 0.551 mol

In your reaction you started with a solution that was approximately 8 M acetic acid and 4 M isopentyl alcohol. Use the equilibrium expression for this reaction to calculate the final concentrations of water, isopentyl acetate, isopentyl alcohol, and acetic acid (you'll need to use the quadratic equation to solve this expression) assuming that the equilibrium constant is 4.2. Calculate the percent yield of isopentyl acetate to which this value would correspond.

The final concentrations of water, isopentyl acetate, isopentyl alcohol, and acetic acid obtained on using equilibrium expression are 3.4M, 3.4M, 0.6M , 4.6M

Using ICE table:-

      Acetic acid  +  Isopentyl alcohol   ------>    Isopentyl acetate +  water

I         8M                   4M                                           0                           0

E        8-x                   4-x                                          +x                          +x

Equilibrium constant (Keq) = 4.2

On using the equilibrium expression -

Keq = [Product] / [Reactant]

Keq = x^2 / (8-x) (4-x )

4.2  =  x^2 / 32 - 8x - 4x + x^2

BALANCED CHEMICAL EQUATION:

PROCESS:

Answers

Answer:

11.2 grams CaO

Explanation:

It appears that substance X may be calcium carbonate:  CaCO3

CaCO3 can be thermally decomposed to CO2 and CaO in the following balanced reaction:

CaCO3(s) ⇒ CaO(s) + CO2(g)     (with applied heat, 840°C)

The molar ratio between the product, CaO, and the reactant, CaCO3, is 1:1.  If we start with 1 mole CaCO3, we should produce 1 mole of CaO.

We have 20.0 grams of substance X, which we'll label CaCO3.  Calculate the moles of CaCO3 by using its molar mass of 100.1 grams/mole.

 20.0 grams/(100.1 grams/mole) = 0.1998 or 0.200 moles of CaCO3.

This should produce, with a molar ratio of 1 to 1, 0.200 moles of CaO

Convert this to grams CaO by multiply by it's molar mass of 56.1 g/mole:

(0.200 moles)*(56.1 g/mole) = 11.2 grams CaO.  Any less, then blame it on your lab partner.  But don't try taking credit if you have more than 11.2 grams.  Scraping debri off the counter into the beaker doesn't count.

C3H8 has a boiling point than C2H6

Answers

Answer:

C₃H₈ has a higher boiling point than C₂H₆

Explanation:

The boiling point is the temperature at which the intermolecular bonds holding molecules in liquid form are overcome and change the state into a gas. C₃H₈ experiences stronger intermolecular bonds then C₂H₆ because it has more carbons. While the strength of each bond is the same between the two molecules, C₃H₈ has more opportunities to create these bonds due to the higher carbon count.  The more bountiful the intermolecular bonds, the more energy is needed to overcome them all. Thus, C₃H₈ has a higher boiling point.

2 Al(s) + 3 I₂(g) → 2 AlI₃(g)

Answers

Answer:

Explanation:

To find the excess mass of Al, you need to (1) convert grams I₂ to moles I₂  (via molar mass), then (2) convert moles I₂ to moles AlI₃ (via mole-to-mole ratio from equation coefficients), then (3) convert moles AlI₃ to grams AlI₃ (via molar mass). Now that you have the actual amount of AlI₃ produced, you need to (4) convert grams AlI₃ to moles AlI₃ (via molar mass), then (5) convert moles AlI₃ to moles Al (via mole-to-mole ratio from equation coefficients), and then (6) convert moles Al to grams Al (via molar mass). Now that you know the amount of Al actually needed to produce the product, you need to (7) find the excess mass of Al.

Molar Mass (Al): 26.982 g/mol

Molar Mass (I₂): 2(126.90 g/mol)

Molar Mass (I₂): 253.8 g/mol

Molar Mass (AlI₃): 26.982 g/mol + 3(126.90 g/mol)

Molar Mass (AlI₃): 407.682 g/mol

2 Al(s) + 3 I₂(g) -------> 2 AlI₃(g)

 113 g I₂           1 mole             2 moles AlI₃          407.682 g

A city in an arid environment can observe much higher daily temperature swings than a city in a humid environment. This is in large part due to: A. More solar energy is absorbed in arid environments B. Water is densest at 5 C C. The albedo is lower in humid environments D. The specific heat capacity of water You are advising a customer on backup and disaster recovery solutions. The customer is confused between data breaches and data loss and whether the backup solution will protect against both. What explanation can you give? the reservoirs in fig. p6.55 contain water at 20c. if the pipe is smooth with l = 4500 m and d = 4 cm, what will the flow rate in m3/h be for z = 100 m? neglect minor losses. PLEASE HELP!!!!!!! in the example problem,how could you use multiplication to find equivalent ratios with the same amount of water? A liquid that can be modeled as water of mass 0.25kg is heat to 80 degrees Celsius. The liquid is poured over ice of mass 0.070kg at 0 degrees Celsius. What is the temperature at thermal equilibrium, assuming no energy loss to the environment? How much energy must be removed from 0.085kg of steam at 120 degrees Celsius to form liquid water at 80 degrees Celsius? What is the law of supply? How many of the following "goods" do you think conform to the general law of supply? Explain your answer in each case. a. Gasolineb. Cheating on examsc. political favors from legislators d. The services of heart specialistse. Childrenf. Legal divorces how is the process of respiration in reptiles adapted to life on land a mineral originally contained 1,000 radioactive parents. after two half-lives have passed the mineral will contain parent atoms and daughter atoms. enter in the correct numerical values. If a real economic shock shifts the LRAS curve to the left, which of the following will NOT further reduce real GDP growth and inflation? a a decrease in money growth b uncertainty that reduces consumption c a monetary policy rule that is credible d loss of market confidence about the power of monetary policy Which type of light is least useful for photosynthesis in terrestrial plants? briefly design the current exchange of the drainage system development around the terminal could a company like toms have come about absent the role of blake mycoskie? what is the role of the individual in entrepreneurial ventures such as toms? suppose f ( x ) = x 6 x 2 5 . notice that f ( 4 ) = 0.9091 . what does this tell us about the numerator and the denominator of f ? Whenever a new product competes against a company's already existing products and reduces the sales of those products, sunk costs working capital costs erosion costs opportunity costs how many integers less than 9975 are relatively prime to 9975? The reception desk has a tray in which to stack letters as they arrive. Starting at 12:00, thefollowing process repeats every five minutes: Step 1 Three letters arrive at the reception desk and are stacked on top of the letters already in thestack. The first of the three is placed on the stack first, the second letter next, and the third letter ontop. Step 2 The top two letters in the stack are removed. This process repeats until 36 letters have arrived (and the top two letters have been immediatelyremoved). Once all 36 letters have arrived (and the top two letters have been immediately removed),no more letters arrive and the top two letters in the stack continue to be removed every five minutesuntil all 36 letters have been removed. At what time was the 13th letter to arrive removed? Air is used as the working fluid in a Diesel cycle with nonidealities. Some important pieces of information regarding the cycle are: The nonidealities occur during the adiabatic compression and expansion processes. At the beginning of the compression process, the air is at 95 kPa and 22C. The pressure bounds (i.e. the minimum and maximum pressure) for this non-ideal cycle are the same as they would be under ideal operating conditions. Ideally, the compression ratio for this cycle would be rideal = 10. The specific volume at the end of the isobaric expansion is the same for the real cycle and the idealized cycle. The temperature is measured to be 800 K after the adiabatic compression process. The cutoff ratio for the real cycle is r= 2.5. The adiabatic expansion produces 85% of the work it would produce if it were also reversible. Treat air as having constant specific heats at 300 K during your analysis. a) Sketch an ideal Diesel cycle on P-v and T-s diagrams. You do not need to specify any property values on your diagrams. Using the ideal cycles for reference, sketch the non-ideal Diesel cycle described above on the same axes. Again, you need not specify any property values; just focus on getting the general trends correct. b) Determine the isentropic efficiency of the compression process. c) Determine the thermal efficiency of this cycle. d) Determine the ratio of the thermal efficiency of this cycle compared to its ideal counterpart. That is, determine thermal real/thermal,ideal Drying provides the full antiseptic effect.
