Oxidation-reduction, or “redox,” reactions represent one of the major reaction classifications in chemistry. The reactions necessarily involve the transfer of electrons from one species to another. Chemists refer to the loss of electrons as oxidation and to the gain of electrons as reduction. The...
Write the chemical components of the reaction in the standard notation format. In our example, this will be CH4, O2, CO2 and H2O. In chemistry, to "yield" means that whatever is before turns into whatever comes after, so be sure that "yield" is roughly in the middle. That phrase will...
(a) Write reactions to show how glucose separately reacts with (i) NH(2)OH (ii) HNO(3) (iii) ammoniacal AgNO(3) (b) What do you understand by (i) de

Mole-to-Mole Ratio:The law of definite proportions tells us that the compounds form from definite proportions and in a reaction, the reactants and products are in definite proportions to each other as well. That means we use a ...
How can one determine if an ordered pair is a solution to an equation? How do you write a compound which contains calcium (Ca) and the polyatomic ion chlorate (ClO3)? When doing single replacement reactions, how do we know what the element being replaced will be?
This paper investigates the views of science and scientific activity that can be found in chemistry textbooks and heard from teachers when acid–base reactions are introduced to grade 12 and university chemistry students. First, the main macroscopic and microscopic conceptual models are developed. ...
and water and carbon dioxide are two products of a reaction, then it is probably a combustion reaction. Double-displacement reactions tend to involve ionic solutions that produce ionic compounds, one of which forms a precipitate; if you notice a precipitate in your reaction, you know it can li...
Question: How does mass change during a chemical reaction? Building Blocks Of Matter: All matter is made up of tiny building blocks called atoms. Atoms are bonded together to form molecules and compounds, which make up everything that exists in the universe. The amount of matter in a substan...
