refers to the calculations made to find amount of reactants and products in a chemical reaction. Stoichiometry is based on the law of conservation of mass, where the total mass of reactants will have to produce an equal amount of products, supposing the reaction has a 100% reaction rate....
Define : (a) Average rate of reaction (b) Instantaneous rate of reaction. View Solution Differentiate between :Average rate and instantaneous rate of a chemical reaction. View Solution Consider the graph given in Q.9 Which of the following options does not show instantaneous rate of reaction at...
1. The rate of reaction is equal to the change in concentration divided by the time interval in which that change has taken place. 2. The rate of reaction can be expressed in terms of any reactant or product. 3. As concentration of reactant decreases, a negative sign is used to expres...
We use chemistry every day, even if we don’t realize it. When you bake cookies, chemistry changes the ingredients in the oven. Soap cleans your hands because of chemistry. Even brushing your teeth is a chemical reaction. Chemistry helps with cooking, cleaning, and keeping our bodies healthy!

Because no chemical reaction takes place when amixtureis formed, no energy (e.g. heat, light or electrical energy) is released or absorbed during the formation of a mixture. Do mixtures consist of atoms or molecules? Mixturescan consist of either atoms or molecules - but must includeat least...
When asolute(often a solid) is added to asolvent(often a liquid), two processes occur simultaneously. Dissolution is the dissolving of the solute into the solvent. Crystallization is the opposite process, where the reaction deposits solute. In an unsaturated solution, the rate of dissolution is...
What is the rate equation? 01:46 For the reaction, Ester + H^(+) to Acid + Alcohol, rate = k[Ester] [H... 01:26 For a reaction A +2B to C, rate =k[A]^x [B]^y. What is the order of r... 01:15 For a reaction A to B , the rate of reaction becomes twenty seven...
The simplest, and most commonly used, type of multiplexing is duplexing, in which two genes are amplified in a single reaction. Typically, in a relative qPCR experiment designed to determine the fold change differences in gene expression, these will be a single gen...
