Stoichiometry Shenanigans
This involves the study of mass relationships of elements in compounds and mass relationships among reactants and products in chemical reactions.
What is stoichiometry?
This theory explains the different properties of solids, liquids, and gases, describing the behavior of matter in terms of particles in motion.
What is the Kinetic-Molecular Theory?
A mixture that does not have a uniform composition and in which the individual substances remain distinct is called this.
What is a heterogeneous mixture?
This is the ability to do work or produce heat.
What is energy?
This is the measure of a liquid's resistance to flow.
What is viscosity?
If you have 2.00 g of hydrogen and 16.00 g of oxygen, this reactant is all used up, thus determining the amount of product formed in a chemical reaction.
What is the limiting reactant?
This law states that the volume of a fixed amount of gas held at a constant temperature varies inversely with the pressure.
What is Boyle's Law?
These are mixtures containing particles that settle out if left undisturbed.
What are suspensions?
Energy due to the composition of an object and the energy associated with the position of an object are examples of this.
What is potential energy?
The point on a phase diagram where the solid state, the liquid state, and the gas vapor state can coexist is called this.
What is the triple point?
The number of these can be written for any equation using the formula (n)(n-1), where n is the number of reactants and products.
What are mole ratios?
These are the four variables (P, V, T, and n) that are related by the Ideal Gas Law.
What are pressure, volume, temperature, and number of moles?
This type of solution has the maximum amount of dissolved solute for a given amount of solvent at a specific temperature and pressure.
What is a saturated solution?
This is the heat required to vaporize one mole of a liquid substance.
What is molar enthalpy (heat) of vaporization?
The curved surface of a column of liquid is called this.
What is a meniscus?
This is the maximum amount of product that could be produced from a given amount of reactant.
What is theoretical yield?
STP, used in gas calculations, stands for this.
What is standard temperature and pressure?
This is the measure of the amount of solute in a given amount of solvent or solution.
What is concentration?
A chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the form of heat and light is called this.
What is a combustion reaction?
A compound that lowers the surface tension of water is called this.
What is a surfactant?
In the reaction 2H2+O2⟶2H2O, if 4 moles of hydrogen react completely, how many moles of water are produced?
What are 4 moles?
If the pressure exerted by a gas at 100°C in a volume of 0.044 L is 3.81 atm, calculate how many moles of gas are present. (R = 0.0821 L⋅atm / (mol⋅K) and K = °C + 273.15
What is 5.5 x 10-3 mol?
Calculate the molarity of a solution in which 146 g of HCl is dissolved in enough water to make 500 mL of solution. (Molar mass of HCl = 36.46 g/mol and M = moles of solute / liters of solution)
What is 8.01 M?
A breakfast bar contains 170 nutritional calories. Calculate how much energy, in joules, this represents. (1 Calorie (nutritional calorie) = 1000 calories and 1 calorie = 4.184 J)
What is 7.11 x 10⁵ J?
These forces attract molecules and keep them closely packed in a liquid, giving it a definite volume.
What are intermolecular forces?
