Name the source from which litmus solution is obtained. What is the use of this solution?
Dinitrogen and dihydrogen react with each other to produce ammonia according to the following Chemichal equation:
N2g) + H2(g) – 2NH3 (g)
1] calculate the mass of ammonia produced if 2.00 × 10³ g dinitrogen reacts with 1.00 × 10³g of dihydrogen
2] will any of two reactants remain unreacted
3] If yes , which one and what would be it’s mass
Ammonia is found in many household products, such as window cleaners. It turns red litmus blue. What is its nature?
