Question

write a chemical equation for burining of lanthanouds (Ln)in oxygen​

Answer 1

Explanation:

The lanthanides react slowly with cold water (more rapidly with hot water) to form hydrogen gas, and readily burn in air to form oxides. ... For example, samarium and oxygen combine to form the compound samarium oxide. Yttrium has a natural protective oxide coating, making it much more resistant.

Y + 02 ---- YO2

Answer 2

Answer:

The lanthanides react slowly with cold water (more rapidly with hot water) to form hydrogen gas, and readily burn in air to form oxides. Oxides are substances in which a metal and oxygen have chemically combined to form a compound. For example, samarium and oxygen combine to form the compound samarium oxide.

4Ln+3O2--->2Ln2O3
