In an example of a simple chemical reaction, one atom of potassium (K) can react with one atom of chlorine (Cl) to form a molecule of potassium chloride (KCl) with nothing left over. But this is not because potassium atoms and chlorine atoms have the same mass. Instead, it is because...
Peas are much like corn as soon as they mature a chemical reaction occurs that causes the peas’ sugar content to decrease rapidly. A fresh, sweet, juicy pea can rapidly become starchy and hard. The same is true if the pea is shelled and then left on the kitchen counter or in a warm...
When your pinwheel helicopter falls, it is due to the force of the earth’s gravity. Lift, and the design of the rotors help it stay in the air. It naturally falls to the ground, which causes the paper to bend slightly upward due to lift. When your paper helicopter falls, air pushes...
A reaction occurs when particles collide. In this collision the particles transfer enough energy to break old bonds and make new ones. But how can you define the rate at which a reaction occurs? The Rate of Reaction Take a look at a simple reaction like the one below: ...
At some point in your college career, you may be asked to respond to a critical, peer-reviewed article. Your response will need to be critical as well, looking for and pointing out flaws or strong areas in the author's argument and constructing an alter
In the final analysis, in the final analysis is to survive, in order to meet the needs of life! That is to meet the desires of the individual! I think all the origin is a place of "mon human heart"! It can dilute the evolution and sublimation of all of you! What do you think ...

Thus, in a chemical reaction, the total mass of matter involved in the reaction should be constant. Hence, the mass of the reactants equals the mass of the products. Because of this, when a chemical equation is used to represent a reaction, the number of atoms or moles of each elem...
