What is the significance of the derivation of the term atom? That matter appears to be continuous but is actually discontinuous. This means that the continuations of division of a matter would eventually reach a limit to this dividing, a particle that could not be further subdivided. The Greek ph...

Boron reacts with halogens to give the corresponding trihalides. Boron trichloride is, however, produced industrially by direct chlorination of boron oxide and carbon at 500 °C. B2O3 + 3C + 3Cl2 → 2BCl3 + 3CO The carbothermic reaction is analogous to the Kroll process for the conversion of titan...
Niels Bohr was one of the greatest scientists of the 20th century. He created a model of atomic structure and established the foundations of quantum mechanics for which he received the Nobel Prize on December 10, 1922. In this research paper, I am going to write about the background of Niels Bohr, a...
Physicists are very important to our society today, why? Because, they provide the basic answers to the mechanics of life in many ways. In this paper you will learn about the life of William D. Phillips, and his major achievements. You will learn how they cooled and trapped a laser's atoms, to make ...

We were able to ignore the terms on the right side of the equation because we know mass is conserved within the reaction. Also the conservation of atoms tells us that the ratio of moles of copper chloride to aluminum is constant. So given the amount of copper chloride that reacted, we could find the amount of aluminum that reacted. If all the aluminum dissolved and the liquid was still blue, we would know that aluminum was the limiting reagent. We would also be able to calculate the mass of the original aluminum wire if we were able to measure the mass of the leftover copper. ...
