Answer:
As it gets hydrolyzed easily.
Explanation:
The isocyanic acid may get polymerizes easily into cyanuric acid and a polymer cyamelide
Also, even at 0 °C temperature it may react with mositure and gets hydrolyzed into ammonia an carbon dioxide. Thus we generally prepare it in situ. Even after synthesis it is stroed at dry ice or liquid nitrogen at very low temperature.
The lewis structure is shown in the figure.
Answer:
0.9 liters of 4.0 M NaOH solution will react with 1.8 moles of sulfuric acid.
Explanation:

According to reaction, 1 mole of sulfuric acid reacts with 2 moles of sodium hydroxide.
Then 1.8 moles of sulfuric acid will react with:
moles of NaOH.
Molarity of NaOH = 4.0 M
Moles of NaOH= n = 3.6 mol
Volume of NaOH = V


0.9 liters of 4.0 M NaOH solution will react with 1.8 moles of sulfuric acid.
Lead Nitrate is highly soluble in water. 37.65g/100 mL at 20*C
<span>The volume of iron is obtained from the density formula (density= mass/ volume) given the density and mass. In this case, 4,540 grams of iron and a density of 7.86 g/ml are given. The volume obtained from formula is 493.64 ml or 5.78 dL. </span>
Non metals
(It’s both halogens and noble gases ) the other ones which are white(not highlighted) are alkali metals, alkaline earth metals, and transition metals :3
