Answer:
Ammonia and Hydrogen Chloride.
Explanation:
Assuming this is what you're referring to, Ammonia (NH3) and Hydrogen Chloride(NCI3). The concentrated ammonia (NH3) is placed on a pad in one end of a tube and hydrochloric acid (NCI3) on a pad at the other. Shortly after the gases will begin diffusing far enough to meet, a ring of solid ammonium chloride (NH4Cl) will be formed.

Answer:
3 grams
Explanation:
14 g of N2 is 1/2 mole
If you halve the N2 in the balanced equation , you have to halve the H2 down to 1.5 moles of H2 which is 3 grams
Time passed Time passed 14C initially present 14C at end of half-life
(half life) (Years)
........................................................................................................................
0 0 1,000,000 1,000,000
1 5750 ..... 5,00,000
2 11500 ..... 2,50,000
3 17250 ..... 1,25,000
4 23000 ..... 62,500
Since, wood sample contained 1/16 of current atmospheric concentration of 14C. It means that sample has crossed 4 half-life. Number atoms left are 4 half life = 62,500
