Which will not appear in the equilibrium constant expression for the reaction below?

Chemistry
1 answer:
enot [183]2 years ago
6 0

Answer:

[C]

General Formulas and Concepts:

<u>Chemistry</u>

<u>Kinetics</u>

  • Rate Laws

<u>Equilibrium</u>

  • Equilibrium Expressions

Explanation:

Equilibrium Expressions are only written for either aqueous solutions or gases. Solids and liquids are negligible for equilibrium. Our equilibrium constant expression would be \displaystyle K = \frac{[CO][H]}{[H_2O]}.

∴ Carbon C (s) is not included in the expression and is our answer.

During a laboratory experiment, 9.68 g of iron reacted with excess sulfur to form 13.8 grams of iron II sulfide. Calculate the p
Daniel [21]

Answer:

Percent yield = 90.8%

Explanation:

The reaction of Fe with S to produce FeS is:

Fe + S → FeS

<em>Where the moles of Fe added in excess of S are the moles of FeS</em>

<em />

Now, percent yield is defined as 100 times the ratio between actual yield (13.8g of FeS) and theoretical yield (15.2g FeS):

Percent yield = 13.8g / 15.2g * 100

<h3>Percent yield = 90.8%</h3>

What is the salinity seawater?
BigorU [14]
<span>Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5% or 35 parts per thousand. This means that for every 1 liter (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.

What differences do you notice when you heat up the brick and the iron at same temperature?
Tpy6a [65]

After heating the brick and the iron, it is observed that the brick heats up quicker and the brick releases energy quicker.

<h3>What is thermal energy?</h3>

Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other.

The iron has more energy than the brick even though it is at the same temperature. That means that the iron must have more particles than the brick.

Iron and brick are both solids and have the same volume, so the difference in total energy must be due to atomic composition.
