Find the mass of 5.60 L O2 at 1.75 atm and 250.0 K

Answers

Answer 1

Answer:

Moles O2 = pV/RT = 2.75 x 5.60 / 0.08206 x 250=0.751

mass = 32 g/mol x 0.751 mol= 24.0 g

Answer 2

The mass of 5.60 Liter oxygen at 1.75 atm pressure and 250.0 K temperature is 24.0 gram.

What is ideal gas equation?

Ideal gas equation is a hypothesis which tells about the behavior of gas at standard condition and it is represented as:

PV = nRT, where

P = pressure = 1.75 atm

V = volume = 5.60 L

R = universal gas constant = 0.0821 L.atm /K.mol

T = temperature = 250 K

n is the moles of gas which will further define as:

n = W/M, where

W = required mass

M = molar mass

Now putting all the value in the above ideal gas equation and calculate for moles as:

n = (1.75)(5.60) / (0.0821)(250)

n = 0.751

Molar mass of oxygen is 32 g/mol and we calculate their required mass as:
W = 32 g/mol x 0.751 mol= 24.0 g

Hence, the required mass of oxygen is 24.0 g.

Using the balanced chemical equation:
4NH3 + 302 --> 2N2 + 6H20
Determine the amount of grams of N2 is produced If 4.03 moles of NH3 react?

Answers

Your answer and workings are all mentioned in the picture below.

Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

Reaction stoichiometry

In first place, the balanced reaction is:

4 NH₃ + 3 O₂ → 2 N₂+ 6 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

NH₃: 4 molesO₂: 3 molesN₂: 2 molesH₂O: 6 moles

The molar mass of the compounds is:

NH₃: 17 g/moleO₂: 32 g/moleN₂: 28 g/moleH₂O: 18 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

NH₃: 4 moles ×17 g/mole= 68 gramsO₂: 3 moles ×32 g/mole= 96 gramsN₂: 2 moles ×28 g/mole= 56 gramsH₂O: 6 moles ×18 g/mole= 108 grams

Mass of N₂ formed

The following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?

[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]

mass of N₂= 56.42 grams

Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

Answer:

This is not a redox reaction.

Explanation:

A redox reaction is a reaction that involves reduction and oxidation processes. The best way to identify a redox reaction. Changes in the oxidation number f the species indicates that it is a redox reaction.

Na+

Reactant side = +1, Product Side = +1; No change

Cl-

Reactant side = -1, Product Side = -1; No change

Ag+

Reactant side = +1, Product Side = +1; No change

Reactant side = +5, Product Side = +5; No change

Reactant side = -2, Product Side = -2; No change

There is no change in any of the oxidation numbers, Hence this is not a redox reaction.

Sand:
0.0625-2mm
By another definition, in terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or 1/16 mm) to 2 mm. An individual particle in this range size is termed a sand grain.

Cobble:
64-256 mm
(a) A rock fragment larger than a pebble and smaller than a boulder, having a diameter in the range of 64-256 mm (2.5-10 in., or -6 to -8 phi units) being somewhat rounded or otherwise modified by abrasion in the course of transport; in Great Britain, the range of 60-200 mm has been used.

Silt:
0.002 to 0.05mm
Silt particles are from 0.002 to 0.05 mm in diameter. Sand ranges from 0.05 to 2.0 mm. Particles larger than 2.0 mm are called gravel or stones. Most soils contain a mixture of sand, silt and clay in different proportions.

Boulders:
>256 mm
In geology, a boulder is a rock fragment with size greater than 256 millimetres (10.1 in) in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move.
