Problem 30E

The Gas Laws (Section)

Nitrogen and hydrogen gases react to form ammonia gas as follows:

N2(g) + 3 H2(g)→2 NH3(g)

At a certain temperature and pressure, 1.2 L of N2 reacts with 3.6 L of H2. If all the N2 and H2are consumed, what volume of NH3, at the same temperature and pressure, will be produced?

Chapter 3 The Metric System Basic Units and Symbols Length – meter – m Mass – gram – g Volume – liter – L Time – second – s Metric Prefixes A prefix can be attached to any unit to increase or decrease its size by a factor of 10. To increase the size of the unit: kilo = one thousand To decrease the size of a unit: centi = one hundredth Milli = one thousandth Metric Conversion Factors Exact equivalent: 1 kilometer = 1 x 10³ meter 1 km = 1 x 10³ m 1 cm = 1 x 10⁻²m or 1 m = 100 cm MetricMetric Conversions Example: The radius of a tin atom is 1.41 x 10⁻⁸ cm. What is the radius of the atom in m
