The graph below shows how the pressure and volume of a gas vary when the
number of moles and the temperature of the gas are held constant. What
happens to the pressure inside a sealed syringe of gas as the volume of the
syringe increases?

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?
