Write out the balanced equation for the reaction that occurs when ca(oh)2 and h3po4 react together. you do not need to make your subscripts smaller; just write them out at regular numbers. for example: ca(oh)2.

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 4.20 mol fe and 6.70 mol nio(oh) react?
