Rates of Reaction: The term "rate of reaction" means how quickly (or slowly ) a reaction happens. It also tells you at what rate the reactants are used up, or the products are formed in a chemical reaction. For calculating the rate of a chemical reaction, you will need the following: The mass (or the volume) of the reactants (or the products) at the beginning and the end of the reaction. The total amount of time for the reaction. Once you have both the values, just divide the change in the mass (or the volume) by the total time taken for the reaction. This will be the rate of the reaction. The rate of reactions is usually measured in: For change in mass : Grams per second (g s -1 ), or For change in volume : Cubic decimetre per second (dm 3 s -1 ) Important: Rate of reaction c
Similes and Metaphors Grammar / Simile and Metaphor Level: Beginner (10 minute read) In English language, both similes and metaphors are used for making comparison between two things. This makes sentences interesting, while also stating or describing an important idea or fact. Let's look at what they are and how to use them. What is a Simile?
