A sample of helium gas at a pressure of 2.07 atm fills a flask with a volume of 350. mL at a temperature of 18.0°C. If the gas is transferred to another flask at a pressure of 1.78 atm with a volume of 275 what will the new temperature of the gas be? Type your answer with the correct number of sig figs and units.

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?
