Answer:

28%

Explanation:

Basically, all o did was write the equations, balance it and solve for them. Also, at the place I stared, I used simultaneous equation to solve it. Multiplying by 8 and also 3.

It's a pretty straightforward question.

At the final step that's missing, I Did

(y)C3H8 = 2.8 / ( 2.8 + 7.1)

(y)C3H8 = 0.28

Answer:

Causes the equilibrium to shift to the left, in favor of making more reactants, and K decreases.

Explanation:

Le Châtelier's principle states that if there is a stress in equilibrium, the reaction will shift to restore the equilibrium. An exothermic reaction loses heat for the surroundings, so the equilibrium must be represented as:

Reactants ⇔ Products + Heat

Then, when more heat is added, to restore the equilibrium, the reaction shift to the left ("consuming" heat), in favor of making more reactants.

The equilibrium constant (K) is:

K = [Products]/[Reactants]

So, [Reactants] will increase, and K must decrease.

The following properties are either physical or chemical. Which one is different from the rest based on those two categories?
inysia [295]

Mass

Explanation:

Mass is different from the rest based on those two categories.

Physical properties are the properties of matter that are usually determined with our senses like taste, feel, color, odor e.t.c

Chemical properties are the properties that relates to a substance when changes are occurring to it.

These properties are boiling point, magnetism and thermal conductivity among others.

Mass is not a physical nor chemical property. It is classified as an extensive property of substances which varies according to the amount of matter it contains.
