1.Согласно закону эквивалентов м(Ме)/Мэкв(Ме)=м(О)/Мэкв(О)м(О)=2-1,2=0,8 гМэкв(О)=12/2=8 г/мольМэкв(Ме)=1,2*8/0,8==12 г,моль(судя по всему это - магний_2. Согласно правилу суммы Мэкв (МеО)=Мэкв (Ме) +Мэкв (О)=12+8=20 г/мольОтвет: Мэкв 9Ме)=12 г/моль, Мэкв(МеО)=20 г/моль

Million – watt U.S. solar boiler is tested in French Pyrenees
At a French solar energy installation here in the Pyrenees, two US engineers have successfully tested a one-megawatt power-plant steam boiler designed to run on sunlight. The boiler worked successfully in a recent demonstration. The engineers were pleased with the boiler's performance because it was the first time that a steam boiler – other than a laboratory-size

model – has worked using sunlight. It is regarded as an important step in the research and development of this technology. The one-million-watt boiler was specially built, to be tested in France. The French have the world's largest solar-energy test installa- tion, which is primarily used to melt pure metals and ceramics at high temperatures – up to 6,000 degrees Fahrenheit. But this installation could also be used to power a one megawatt (1,000-kilowatt) boiler. The 10-ton boiler was finished in February, tested with lamps si- mulating sunlight and then shipped to France. The eight-foot-tall boiler, which was carried atop a truck, scraped a bridge on the way up one mountain. During the tests at Odeillo, 63 mirrors, each 20 by 25 feet, re- flected sunlight from 2,000 small mirrors and focused the captured light into the boiler's cavity. The temperature rose to more than 1,500 degrees Fahrenheit and within an hour the boiler began to "superheat" its 200 gallons of water. With steam at full pressure, the boiler can be used in the usual way to run conventional turbines to generate electricity. The one – megawatt boiler is a prototype, Larger five- and 10 – megawatt boilers, which will be 29 and 60 feet tall respectively, are be- ing built by three US companies under contract from the Federal Energy Research and Development Administration.
