As the temperature of a reaction increases , it is expected that the reacting particles collide

1 answer:

6 0

It has been proven by Science that when the temperature of a reaction increases, the particles will gain energy and will collide faster and frequently.

Have a nice day! :)

Assuming ideal behavior, how many moles of argon would you need to fill a 14.0×12.0×10.0 ft room? assume atmospheric pressure of

UNO [17]

We use the formula:

PV = nRT

First let us get the volume V:

volume = 14 ft * 12 ft * 10 ft = 1,680 ft^3

Convert this to m^3:

volume = 1680 ft^3 * (1 m / 3.28 ft)^3 = 47.61 m^3

n = PV / RT

n = (1 atm) (47.61 m^3) / (293.15 K * 8.21x10^-5 m3 atm / mol K)

How many moles of oxygen are produce dif 11.0 mol of al are produced

ycow [4]

Answer:

8.25 moles

Explanation:

Given parameters:

Number of moles of Al produced = 11 moles

Unknown:

Number of moles of oxygen produced = ?

Solution:

To solve this problem, we need to understand the problem.

The decomposition of an aluminium oxide must has produced oxygen and aluminium,

2Al₂O₃ → 4Al + 3O₂

now since the known is the oxygen gas; we can find the unknown aluminium:

3 mole of O₂ was produced with 4 mole of Al

x mole of O₂ will be produced with 11 moles of Al

x = $\frac{3 x 11}{4}$ = 8.25 moles
