This is because a chemical reaction takes place causing a change in the milk and the nail. In fact, regular body processes such as respiration and digestion are also chemical reactions. A chemical reaction is expressed using a chemical equation. Let’s dive in and learn about chemical ...
Step-by-Step Solution:1. Definition of Chemical Reaction: A chemical reaction is a process where one or more substances (reactants) are transformed into one or more new substances (products). This transform
If possible, make the equation more informative by indicating the physical states of the reactants and products, the heat changes that occur in the reaction, and the conditions under which the reaction occurs. This step may be skipped if you do not have enough information about the physical s...
Understand the concept of balancing chemical Equation | Law of conservation of mass, reactants and Products | Why is it important to balance a chemical equation,balanced chemical equation for magnesium oxide.
Chemistry - Chemical Reactions & Equations - A process in which one or more chemical substances react with other chemical substance and converted to one or more different substances is known as chemical reaction.
And how can I predict the products of a chemical reaction if its reactants are given. Is it done by understanding the types of chemical reactions. One of my teachers said that it could be done like this : If you're given two elements as reactants and you know that they will react,...
In some chemical reactions, a substance called a catalyst is used. A catalyst speeds up a reaction without being used up Because a catalyst is not used up, it is neither a reactant or a product and is written above the arrow in the equation. 2H2O2(aq) ---> 2...

Modern chemical equations reflect our understanding of matter being composed of atoms and of chemical reactions as a process of breaking bonds and rearranging atoms into new compounds. Mass is conserved in a chemical reaction, and the number of particles on each side of the equation must reflect ...
