Assume co-hb is an unhydrated sphere. calculate its frictional coefficient f0 . assume the solution viscosity is η=0.891×10−3kgm−1s−1

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?
