The atomic number of an element gives us the number of the proton or positive charges present in the nucleus of the atom. Answer and Explanation: Given: The mass of water is m = 200 g. The molecular mass of water is M=18 g/mol. Number of moles of water in 200 g is given ...
The complex (Cr(H2O)4Cl2) contains Cr(II). What is the charge on the complex? What is the difference in the arrangement of T-form and R-form hemoglobin? 1. Draw the structure of amino acid lysine at pH = 1.00 and pH = 12.00. 2. Find the overall charge of the amino acid a...

What makes SmartWater so special? Is it really any different from regular water? There are a couple things, but neither will improve your IQ.
Engines need combustion, so it sounds both dangerous and perfect all at once. Tell me more about the upsides first. Contrary to the lyrics of a popular ‘90s song that charted at No.1 for 15 (!) weeks,hydrogenis all around you. Being one of the key elements of water (H2O - with...
A molecular orbital energy level scheme is estimated which is able to account for both the "crystal field" and the "charge transfer" spectra of VO(H2O)(5)(2+) and related vanadyl complexes. The paramagnetic resonance g factors and the magnetic susceptibilities of vanadyl complexes are discussed...
Total dissolved solids can also be used as a rough check on the accuracy and completeness of a comprehensive test of individual ions. Ideally, total dissolved solids should equal the sum of the individual ions. If there is a big discrepancy, it would suggest that some significant ion was not...

Water filtered through the OptimH2O is much cleaner than tap water but doesn't have the flat taste of deionized or distilled water. It's gentler on skin and hair and easier to cook with, too. Deionization purifies water, but it's not the type of purity you need for drinking water. An...
