Question

write chemical formula of carbon disulphide using crisscross method

Answer 1

Explanation:

The name of the compound tells you:

1 carbon atom + two sulfur atoms = CS2.

“di” == 2, e.g., carbon dioxide = CO2.

Many compounds tell you exactly what’s in them:

Sulfur dioxide: SO2

Sulfur trioxide: SO3

Carbon monoxide: CO

Carbon tetrachloride: CCl4

Other compounds have common names, mostly for historical reasons:

water: dihydrogen monoxide = H2O

methane: carbon tetrahydride = CH4

ammonia: nitrogen trihydrie = NH3

Suggestion: Use your favorite search engine to find the formula for almost any compound.
