You probably already know that cooking involves a ton of chemistry. Bread rises because of the reaction between the flour and leavener, and the delicious crust on your steak is formed by the Maillard reaction. Understanding the chemistry going on behind the scenes is one of the best ways to improve the quality of your food—it's much easier to fix a problem when you know what's causing it.
When you have a lot of equipment, dragging it everywhere with you can be a pain, especially when the weather's bad. Sure, you can put it in a camera bag, but a lot of them don't protect your stuff from water, and waterproof cases can get expensive.
Keeping apples or avocados from browning after being cut is impossible; within minutes of being exposed to air, these fruits (yes, avocado is a fruit) begin to brown. No matter what you try—adding lemon juice, keeping the pits in place, immediately sealing the produce in an airtight bag—brown discoloration always occurs. However, air is not the only reason that foods like apples, avocados, and lettuce brown: it's also due to the knife you're using.
In this video, we learn how to easily balance a chemical equation. In a balanced equation, there should be the same number of atoms on both sides of it. There are no rules that explain how you get a balanced reaction from expression. First, start on the molecule or compound that is the most atomically complex. After you look at this, you can learn how to make the rest of the equation equal to each side. This is a complex process that you must walk through to figure out, but it will result in ...
