**PLZ PLZ HELP ITS A TEST AND DUE SOON I WILL GIVE BRAINLIST TO THE RIGHT ANSWER** Zn + 2HCI → H2 + ZnCl2

At STP, how many liters of hydrogen gas (Hz) will be produced if 31.2 g of zinc is allowed to react with excess hydrochloric acid?
A)10.7L
B)2.82 L
C)9.66 L
D)4.30 L

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
