Number Have Meaning:A balanced chemical equation is a way of representing what is happening in the real world of chemical reactions. The number in front of a chemical formula is called the coefficient and it te
How many more protons than electrons does this piece of plastic have? Electrons and Protons: If the number of protons is higher than the number of electrons in an atom, then the net charge would be positive, whereas if the number of electron...
When Mendeleev first published the original periodic table in 1869, it contained only 63 elements — about half as many as there are today. His table had gaps to leave room for elements that had not been yet discovered, and Mendeleevused the position of these gaps to predict the properties ...
How many isotopes does actinium have? How many nucleons are there in the sulfur-32 isotope? What is helium-4 isotope? How many neutrons are in californium? What is the mass number of each zirconium isotope? How many isotopes does protactinium have? How many isotopes does californium have? I...
bromine and chlorine, but not fluoride. To remove fluoride from drinking water you will need activated alumina defluoridation filters. They are quite expensive at $30 each. They have to be replaced after a few days of use. Do not boil your water if it is fluoridated because it raises ...
How many moles of acetic acid are in a 400 mL bottle of vinegar if the concentration is 0.89 M? 5.0 g of calcium carbonate is equivalent to how many moles? How much Fe_2(CO3)_3 should be weighed out to have 0.750 mole? How many moles of magnesium ions are in a 15.0 mol sample...
The best chemistry labs are as entertaining as they are informative. They should simultaneously demonstrate the lesson and pique student interest in the laws that govern chemical change. While they are by no means the only way to entrance your students,

1,l-diphenylethylene which cannot go very deep within the micellar core because of its very high hydrophobocity, uses for its reaction with bromine water molecules close to the interfacial region the electrophilicity of which is markedly greater than that of bulk water. In contrast, chloromethyl...
In the case of Ionic Contamination testing, like any de-ionised solution, it is hungry for ions and will aggressively seek them out. Unlike Ion Chromatography, it is not able to discriminate between individual ionic salts: Bromine, Chlorine etc., but its original and primary purpose is to ...
