What volume (in L) of oxygen will be required to produce 77.4 L of water vapor in the reaction below?
Nostrana [21]

Answer:

For the production of 77.4 L water 90.3 L oxygen is required.

Explanation:

Given data:

Volume of oxygen required = ?

Volume of water produced = 77.4 L

Solution:

Chemical reaction equation:

2C₂H₆ + 7O₂  →  4CO₂ + 6H₂O

1 mole = 22.414 L

There are 6 moles of water = 6×22.414 = 134.5 L

There are 7 moles of oxygen = 7×22.414 = 156.9 L

Now we will compare the litters of water and oxygen:

                              H₂O           :              O₂    

                              134.5         :              156.9

                                77.4         :             156.9/134.5×77.4 =90.3 L

So for the production of 77.4 L water 90.3 L oxygen is required.

Can u guys help on 22. It will only take a min.
Anni [7]

Answer:

Alpha > beta>gamma

Explanation:

Comparing only the three common types of ionizing radiation, alpha particles have the greatest mass. Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.

The percentage yield is 72.8 %.

<em>Step 1</em>. Calculate the <em>mass of Br₂</em>

Mass of Br₂ = 20.0 mL Br₂ × (3.10 g Br₂/1 mL Br₂) = 62.00 g Br₂

<em>Step 2</em>. Calculate the <em>theoretical yield</em>

M_r:           159.81    266.69

         2Al + 3Br₂ → 2AlBr₃

Moles of Br₂ = 62.00 g Br₂ × (1 mol Br₂/(159.81 g Br₂) = 0.3880 mol Br₂

Moles of AlBr₃ = 0.3880 mol Br₂ × (2 mol AlBr₃/(3 mol Br₂) =  0.2586 mol AlBr₃

Theor. yield of AlBr₃ = 0.2586 mol AlBr₃ × 266.99 g AlBr₃)/(1 mol AlBr₃)

= 69.05 g AlCl₃

<em>Step 3</em>. Calculate the <em>percentage yield </em>

% yield = (actual yield/theoretical yield) × 100 % = (50.3 g/69.05 g) × 100 %

= 72.8 %

which of the following halides reacts more slowly in an SN1 reaction: 5-chloro-1,3-cyclopentadiene or 7-chloro-1,3,5-cycloheptat
Rudiy27

Answer:

5-chloro-1,3-cyclopentadiene

Explanation:

5-chloro-1,3-cyclopentadiene will react more slowly in an SN1 reaction. ( i.e. No reaction as the product is unstable ) attached is the representation of the rate of reaction of both Halides which shows that 5-chloro-1,3-cyclopentadiene reacts the slowest .

Also During SN1 reaction Carbocation is formed .

Attached below is the solution explanation

Which compounds are Lewis acids? Select all that apply
sineoko [7]

Answer:

A, C and D

Explanation:

Lewis acid  are compounds that accept a pair of non-bonding electron while Lewis base  are compound that donate non-bonding electron pairs. Lewis acid in the options are NaHCO₃ because it has both acidic and basic properties ( ampholyte),  (CH3CH2)2HC+ is deficient of electron and  BBr3 because boron has an incomplete octet configuration and deficient of two electron
