Chemistry: Charles’s Law (Gas Laws) with 2 examples | Homework Tutor

For a gas, temperature and volume are directly proportional. Keeping everything else constant,as the temperature of a gas goes up, its volume goes up. As the temperature of a gas goesdown, its volume goes down.If you heat up a gas, it expands – the gas particles move faster, and they take up morespace. Imagine a…

Chemistry: Balancing Chemical Equations (algebraic method) | Homework Tutor

Our second balancing chemical equations video shows you a different method – an algebraicmethod. Some people love algebra – it has a power to reduce all sorts of hairy problemsto systems of equations with variables – knowns and unknowns, and if that approach appealsto you, you should try this method of balancing chemical equations. Let’s…

Chemistry: Intro to Stoichiometry with Grilled Cheese Sandwiches | Homework Tutor

Stoichiometry is a kind of calculation in chemistry. It’s sort of like bookkeeping.Stoichiometry lets you figure out how much of a substance is used up or produced in achemical reaction. You need two things to do stoichiometry:1. A balanced chemical equation (balanced is absolutely essential here)and 2. Some measured values (the amount of some of…

Chemistry: Average Atomic Mass (amu, Daltons, etc.) – 2 examples | Homework Tutor

Every element has a characteristic atomic mass, because they each have adifferent number of protons, neutrons, and electrons. Most of the time, you won’t usethe actual masses of each element’s atoms. Subatomic particles are so tiny – theirmasses are so small that it would make problem-solving unwieldy. For instance,the mass of a proton is 1.67…

Chemistry: Balancing Chemical Equations | Homework Tutor

When scientists established that everything was made of atoms – we call this The AtomicTheory – the Law of Conservation of Mass came to be stated as“Atoms are neither created nor destroyed during any chemical reaction.”What this means for us is – when you are writing out a chemical reaction – a chemical equation– you’d…
