The concept of equilibrium
This is a balance between two things
What is equilibrium?
This equation shows the ratio of products to reactants at equilibriums
What is the equilibrium expression?
These three things will cause equilibrium to shift if they are changed.
What are temperature, pressure, and concentration?
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?
In physics, equilibrium typically is the balance between these, which can transfer energy
What are forces?
This is used to represent the ratio of products to reactants when writing the equilibrium expression
What is the equilibrium constant?
Changing this changes the equilibrium constant for a particular equation
What is the temperature?
A change in this denotes a change in enthalpy
What is temperature?
The reason the sky is blue
What is the scattering of light?
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?
These go on the bottom of the equilibrium expression
What are the reactants?
The equilibrium of a reaction will shift toward the side with fewer gas molecules when this is increased
What is the pressure?
When modeling equilibrium, it is often useful to model this, the change in energy, as a product or a reactant.
What is heat?
The number of grams in one mole of a substance
What is the molar mass?
This word refers to a reaction which can proceed in two direction, forward and reverse.
What is reversible?
In the equation 2H2O ⇌ 2H2 + O2, the concentration of this molecule is NOT squared in the equilibrium expression
What is O2?
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?
For an endothermic reaction, increasing the temperature will shift equilibrium in this direction.
What is to the right toward the products?
The 44th president of the United States, this man, was awarded a nobel peace prize when elected.
Who is Barack Obama?
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?
These are not included in the equilibrium expression because their concentration does not vary
What are pure solids and liquids?
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)?
For an exothermic reaction, raising the temperature will shift the equilibrium in this direction
What is to the left toward the reactants?
This is the traditional date of Christmas celebrations in the Eastern Orthodox church.
What is January 7?
