This is a balance between two things

What is equilibrium?

100

This equation shows the ratio of products to reactants at equilibriums

What is the equilibrium expression?

100

These three things will cause equilibrium to shift if they are changed.

What are temperature, pressure, and concentration?

100

The heat content of a system

What is enthalpy?

Armenia, an asian country which is facing ethnic cleansing from Azerbaijani, celebrates Christmas to show it follows this religion, founded around 30 CE

What is Christianity?

200

In physics, equilibrium typically is the balance between these, which can transfer energy

What are forces?

200

This is used to represent the ratio of products to reactants when writing the equilibrium expression

What is the equilibrium constant?

200

Changing this changes the equilibrium constant for a particular equation

What is the temperature?

200

A change in this denotes a change in enthalpy

What is temperature?

200

The reason the sky is blue

What is the scattering of light? 

300

Equilibrium is considered to be reached in chemistry when the rate of the forward reaction equals this.

What is the rate of the reverse reaction?

300

These go on the bottom of the equilibrium expression

What are the reactants?

300

The equilibrium of a reaction will shift toward the side with fewer gas molecules when this is increased

What is the pressure?

300

When modeling equilibrium, it is often useful to model this, the change in energy, as a product or a reactant.

What is heat?

300

The number of grams in one mole of a substance

What is the molar mass?

400

This word refers to a reaction which can proceed in two direction, forward and reverse.

What is reversible?

400

In the equation 2H2O ⇌ 2H2 + O2, the concentration of this molecule is NOT squared in the equilibrium expression

What is O2?

400

In the combustion reaction CH4(g) + 2O2(g) ⇌ CO2(g) + 2H2O(g), this is the effect increasing the concentration of H2O will have

What is shift to the left towards the reactants?

400

For an endothermic reaction, increasing the temperature will shift equilibrium in this direction.

What is to the right toward the products?

400

The 44th president of the United States, this man, was awarded a nobel peace prize when elected.

Who is Barack Obama?

500

A reaction in which all of the reactants are transformed to products is said to have gone to this, a state of finality.

What is completion?

500

These are not included in the equilibrium expression because their concentration does not vary

What are pure solids and liquids?

500

In the combustion reaction CH4(g) + 2O2(g) ⇌ CO2(g) + 2H2O(g), this is the effect decreasing the partial pressure of methane will have

What is shift to the left (toward the reactants)?

500

For an exothermic reaction, raising the temperature will shift the equilibrium in this direction

What is to the left toward the reactants?

500

This is the traditional date of Christmas celebrations in the Eastern Orthodox church.

What is January 7?
