HMDS also reacts with moisture in the air and gradually converts to NH3 and methyl silanol. (CH3)3-Si-NH-Si- (CH3)3 + H2O = 2(CH3)3-Si-OH + NH3 Therefore, HMDS must be considered as one of the primary sources of NH3. When excessive HMDS exists in the cleanroom air, it will ...
A polysialic acid compound is reacted with a hetero-bifunctional reagent to introduce a pendant functional group for site-specific conjugation to sulfhydryl groups, for instance side chains of cysteine units in drugs, drug delivery systems, proteins or peptides. The functional group is, for instanc...
If a solution has (OH-) = 4.2 x 10-12 M, what is (H3O+)? Classify this solution as acidic or basic. A solution which has an (OH-) = 3.4 * 10^-12 M. Is it acidic, basic, or neutral? Which one of the following is a characteristic of a metal? A. reacts with bases to ...
If we can dissolve a compound in a polar solvent such as water such that the cation-anion pairs of the compound are released into the solution, that compound is an electrolyte. The electrolytes that ionize (break down and release the ions to the solution) easily are strong el...
This makes it easier to coat a Si wafer surface with photoresist.2{-Si-OH} + (CH3)3-Si-NH-Si- (CH3)3 =2{Si-OH-Si(CH3)3} + NH3HMDS also reacts with moisture in the air and gradually converts to NH3 and methyl silanol.(CH3)3-Si-NH-Si- (CH3)3 + H2O = 2(CH3)3-Si-OH...
Formula mass is the mass obtained by adding the atomic masses of each atom of a compound. It is expressed in the atomic mass unit (amu)r. It is calculated for ionic compounds. Answer and Explanation:1 The formula mass for each compound is ...
