Which would you expect to have the higher melting point, CaO or CS2?


CaO Calcium oxide also known as quick lime has a melting point of 2572°C .

CS2 Carbon disulfide has a melting point of -110.8 °C .

I would expect carbon oxide to have the higher melting point because:

-CS2 is a liquid whereas calcium oxide is a solid at room temprature
- CS2 is extremely flammable whether as calcium oxide is not
