C) 1 molecule of nitrogen reacts with 3 molecules of hydrogen to give 2 molecules of ammonia. Lithium Dichromate. In its pure or concentrated form, is extremely dangerous which can lead to diarrhoea. The ions combined to form a compound are NH4+ and P3-. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. FeCrO4. The reason is that the molar mass of the substance affects the conversion. What is the reflection of the story of princess urduja? When iron (ii) ions and chromate ions combine two form a compound, each ion will contribute a mole of ion towards the formation of the compound. It is created by the sintering of chromium(III) oxide and iron(II) oxide at 1600 C.
