Balance the equation and indicate whether it is a synthesis reaction, a decomposition reaction, a single-displacement reaction, a double-replacement reaction, or a combustion reaction.
KCN(aq)+H2SO4(aq) - K2SO4(aq)+HCN(g)

What is the empirical formula of c6h18o3? ch3o c2h5o c2h6o c2h5o5

A5.000 g sample of niso4 h2o decomposed to give 2.755 g of anhydrous niso4. what is the formula of the hydrate? what is the full chemical name for the hydrate? what is the molar mass of the hydrate? niso4•_h2o what is the mass % of water in the hydrate?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
