Answer:
0.21 g
Explanation:
The equation of the reaction is;
NaCl(aq) + AgNO3(aq) -----> NaNO3(aq) + AgCl(s)
Number of moles of NaCl= 0.0860 g /58.5 g/mol = 0.00147 moles
Number of moles of AgNO3 = 30/1000 L × 0.050 M = 0.0015 moles
Since the reaction is 1:1, NaCl is the limiting reactant.
1 mole of NaCl yields 1 mole of AgCl
0.00147 moles of NaCl yields 0.00147 moles of AgCl
Mass of precipitate formed = 0.00147 moles of AgCl × 143.32 g/mol
= 0.21 g

Answer:
Ranked, Overhead Sprinklers are the worst, followed by flood, with trench being the best option.
Explanation:
Overhead sprinklers waste a lot of water due to evaporation, and are not suitable for fruit like Tomatoes.
Flood irrigation also is wasteful as more soil than necessary is watered. It is also very species limited as most plants do not appreciate a full bath, only a shower.
Trench Irrigation brings water precisely where it is meant to, and loses less water to evaporation of watering what does not need it.
So you had to pick one, use Drip Irrigation instead for a small garden. If these are the only options, go for trench.
