241. No cut in carbon dioxide emission is planned, merely stabilisation by 2005.

242. Controlling carbon dioxide emissions ultimately entails reducing the consumption of energy-intensive goods.

243. It would also reduce sulphur dioxide and nitrous oxide emissions, which cause acid rain, by 42,000 tonnes.

244. Zubrin proposes using the Sabatier process to react hydrogen with carbon dioxide to make water vapor and methane.

245. An increase of applied pressure thus favours formation of solid carbon dioxide.

246. Sodium bicarbonate plus an acid will produce bubbles of carbon dioxide gas.

247. The document proposes the stabilisation of carbon dioxide emissions by 2000 - a target which is likely to disappoint some.

248. In continuous processes, a filter medium containing manganese dioxide oxidizes the iron and removes it as the ferric hydroxide.

249. Fish take in oxygen from the water and excrete ammonia and carbon dioxide through their gills.

250. Much progress has been made countrywide to reduce sulphur dioxide levels, which have fallen by nearly half since 1970.

251. Carbon dioxide, a principal ingredient of the exhaust gases made during combustion of hydrocarbons, has a molecular weight of 44.

252. Look at how much the children loved seeing that frozen carbon dioxide.

253. All three books also cover the effects of carbon dioxide emissions in the atmosphere.

254. Sulphur dioxide particles in the atmosphere act as reflectors and bounce some of the sun's rays back into space.

255. Increase of pressure usually favours the formation of the solid-as we shall see in the carbon dioxide phase diagram below.

256. The yeast feeds on the sugar and produces alcohol and carbon dioxide.

257. The cocktail of greenhouse gases includes chlorofluorocarbons, methane,(Sentencedict.com) nitrous oxide and carbon dioxide.

258. Joseph Black had described carbon dioxide in 1756 while Henry Cavendish described hydrogen in 1766.

259. Global anthropogenic sulphur dioxide emission reached 75-100 million tonnes a year in 1980.

260. The net result is that, however one mixes the energy cake, carbon dioxide emissions go on increasing.

261. Nitrogen dioxide levels in central London rose by 40 percent between 1979 and 1989.

262. The products of coal gasification include carbon monoxide, carbon dioxide, hydrogen, methane and nitrogen.

263. Cleaning up city air is also easier than curbing output of carbon dioxide, a gas thought to cause climate change.

264. But the general principle seems secure: we must beware of any further large increases in the carbon dioxide level.

265. These later die and so the carbon dioxide eventually finds its way to the sea floor as sediment.

266. Carbon dioxide results from complete combustion of carboncontaining compounds.

267. A tonne of carbon dioxide is now €28.

268. the emission of carbon dioxide into the atmosphere.

269. Carbon dioxide does not burn, nor does It'support combustion.

270. The blue-green algae that form the stromatolites helped create our present atmosphere by breaking down carbon dioxide and excreting oxygen.
