2. (2-step problem) How many grams of MnSO4 are produced from 15.8 moles of H2SO4? Again, write out the equation and MAP it for this problem before attempting to solve---it’s a different map, with two steps! 5 KNO2 + 2 KMnO4 + 3 H2SO4  5 KNO3 + 2 MnSO4 + K2SO4 + 3H2O

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o
