Gaseous ammonia is injected into the exhaust stream of a coalburning power plant to reduce the pollut ant no to n2n2 according to the reaction: 4nh3(g)+4no(g)+o2(g)⟶4n2(g)+6h2o(g) 4nh3(g)+4no(g)+o2(g)⟶4n2(g)+6h2o(g) suppose that the exhaust stream of a power plant has a flow rate of 335 l/ s at a temperature of 955 k, and that the exhaust contains a partial pressure of no of 22.4 torr. what should be the flow rate of ammonia delivered at 755 torr and 298 k into the stream to react completely with the no if the ammonia is 65.2% pure (by volume)?

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
