Consider 2 Al + 6 HCl → 2 AlCl3 + 3 H2 , the reaction of Al with HCl to produce hydrogen gas. This reaction has a yield of 82.5 percent. How much HCl are needed to produce 14.0 L of H2 at 351 K and 1.11 atm
Which resonance structure for the SCN- ion and the COS molecule would you expect to be more stable
Find out What mass of the NaHCO3 reacts with the vitamin C When the tablet dissolves in H2O, it "fizzes" because the reason for this is the CHO3 reacts with the citric acid(C6H8O7 a weak organic acid) and the vitamin C?
What are some ways to induce recrystallization (Name 3), if your solute refuses to recrystallize after performing the required 7 steps?
Ammonia, NH3, can be synthesized by the following reaction: 2 NO (g) + 5 H2(g) -> 2 NH3(g) + 2 H2O(g) Starting with 86.3 g NO and 25.6 g H2, find the theoretical yield of ammonia in grams
