The Haber process is used to synthesize ammonia (NH3) on a large scale by the reaction of nitrogen gas with hydrogen gas as follows: N2 (g) + 3 H2 (g) → 2 NH3 (9) Consider a reaction between a 3.94 L flask containing nitrogen gas and a 17 L flask of hydrogen gas. Both gases have a temperature of 307 K and the pressures inside both flasks is 1.09 bar. What mass of ammonia (in g) would you expect to be produced at temperature 307 K and a pressure of 1.09 bar?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
