What is the coefficient of Oxygen in the balanced reaction below:

Chemistry
1 answer:
Oksana_A [137]3 years ago
4 0

The coefficient of Oxygen in the balanced reaction : 3

<h3>Further explanation</h3>

Given

Reaction(unbalanced)

C2H4+ O2--> CO2+H2O​

Required

The coefficient of Oxygen

Solution

  • Give a coefficient

C₂H₄+ aO₂⇒ bCO₂+cH₂O​

C, left=2, right=b⇒b=2

H, left=4, right=2c⇒2c=4⇒c=2

O, left=2a, right=2b+c⇒2a=2b+c⇒2a=2.2+2⇒2a=6⇒a=3

The equation becomes :

<em>C₂H₄+ 3O₂⇒ 2CO₂+2H₂O​</em>

Circle the letter next to each sentence that is true concerning the compressibility of gases. a. The large relative distances be
Anuta_ua [19.1K]

Answer:

The large relative distances between particles in a gas means that there is considerable empty space between the particles.

The assumption that particles in a gas are relatively far apart explains gas compressibility.

Compressibility is a measure of how much the volume of matter decreases under pressure.

Energy is released by a gas when it is compressed

Explanation:

The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.

Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.

Which of the following is larger then the atomic radius of phosphorus
Lubov Fominskaja [6]

Answer:

a)the ionic radius of phosphorus

Explanation:

phosphorus=2.8.6

for phosphorus to become stable(2.8.8) it gains two electrons thus the ionic radious increases bcz of the gained electrons

A student followed the procedure of this experiment to determine the solubility product of zinc(II) iodate, Zn(IO3)2. Solutions
Fed [463]

Answer:

Explanation:

Complete the table below and determine the solubility product constant.

[Zn(NO₃)₂] 0, M Initial 0.226, 0.101 0.0452, 0.0118

[KIO₃] 0, M Titrant 0.200, 0.200, 0.200, 0.200

V₀, mL of Zn(NO₃)₂100.0, 100.0, 100.0, 100.0

V, mL of KIO₃ titrant 12.9, 12.4, 13.0, 18.3

What needs to be determined are the following for each column/sample

V0 + V, mL

[Zn²⁺]  + [IO³⁻]    ⇄  [Zn²⁺][IO³⁻]2

log [Zn²⁺][IO³⁻]2

\frac{\sqrt{Zn^{2+}}}{1 + \sqrt{Zn^{2+}}}

Then there's the determination of Ksp itself

log Ksp =  Ksp of Zn(IO3)2 =

Considering this, which of the ion products is closest to Ksp, and why?

Finally, the titration volumes for the first three samples don't vary greatly. However the last sample is considerably larger. Why is this to be expected?

The attached figures shed more light on the solution to this problem

How is radiation different from convention and conduction ?
aniked [119]

Radiation doesn't need any medium, it also can travel in vacuum. unlike that conduction needs a good heat transmitor  and convection travels in air.
