What is an acid? Give some examples. In chemistry, what is an acid? What is the formula for perchloric acid? What is the formula for pentanoic acid? Name these acids: HClO2 and N2F4. What is the name of the compound H2SO4? Is it a strong or weak acid?
Not sure if that is the correct name, but it is a benzene ring connected to an C2H302, the benzene connects to the O first(then COCH3). ***the answers have both the ortho and para product** so which one is it because i dont think its...

meliloti feuP has been previously shown to be required for the expression of a wild-type hypoosmosis-tolerant phenotype through correct exportation of cyclic β-glucans69. These results therefore indicate that low pH induces central regulators which change the saccharidic composition of the bacte...
However, it took him another 15 years to deduce the correct structural formula in 1883 [13]. Only after laboring for another seven years was von Baeyer able to develop a commercially viable synthesis protocol, mainly because the starting materials were so expensive. The breakthrough came in ...
(2008) showed that recognizable surface features were visible from orbit at 1.18 μm and developed a methodology to use other channels to correct for the influence of the atmosphere in the surface emissivity data. Because the ∼1 μm spectral region is sensitive to FeO content in minerals, ...
