Hydrogen cyanide is prepared commercially by the reaction ofmethane, CH4(g), ammonia, NH3(g), and oxygen, O2(g), at hightemperature. The other product is gaseous water.a. Write a chemical equation for the reaction.b. What volume of HCN(g) can be obtained from 20.0 L CH4(g),20.0 L NH3(g), and 20.0 L O2(g)? The volumes of all gasesare measured at the same temperature and pressure.
Chapter Four Relevant Periodic Groups 1) Group 1A = Alkali Metals *they have a charge of 1+ 2) Group 2A = Alkaline Earth Metals *they have a charge of 2+ 3) Group 7A = Halogens * they have a charge of 1 4) Group 8A= Noble Gases * they are neutral. They don’t bond with anything. Elements are formed by nuclear reactions in stars at high temperatures. Rules for Orbital Filling 1) Pauli Exclusion Principle → No two electrons have same four quantum number. 2) Hund’s Rule → Electrons will pair only if there is no orbital of exactly the same energy available 3) Aufbau Principle → Electrons fill in this order ; 1s,2s,2p,3s,3p….etc EXCEPTIONS 1s,2s,3s,3p,4s,3d,
