Reactions reach chemical equilibrium when the rate of the forward reaction is equal to the rate of the backward reaction. To further explain this, let’s say chemical A reacts with chemical B to form …
What’s reaction rate and what factors can affect it? How fast reactants react or how fast products appear in a chemical reaction is called reaction rate. Reaction rate is determined by energy changes …
What’s a chemical equation and why should you balance it? A chemical equation is usually a short way of describing a chemical reaction. The reactants are always written on the left-hand side of the …
What’re the types of chemical reactions? The four types of chemical reactions are: Proton transfer reactions Electrons transfer reactions Radical reactions Lewis acids-base reactions …
