Which of the following statements are correct?

`SF_(4)+BF_(3) to [BF_(2)]^(+)[SF_(5)]^(-)`

`SF_(4)+PF_(5) to [SF_(3)]^(+)[PF_(6)]^(-)`

`SF_(4)+CSF to [CS]^(+)[SF_(5)]^(-)`

`BF_(3)+LiF to [Li]^(+)[BF_(4)]^(-)`

the crystal lattice of ice is mostly formed by covalent as well as hydrogen bonds

the density of water increases when heated from `0^@C" to "4^@C` due to the change in the structure of the cluster of water molecules

above `4^@C` the thermal agitation of water molecules increases. Therefore, intermolecular distance increases and water starts expanding

the density of water incrases from `0^@C` to a maximum at `4^@C` and the entropy of the system increases

Fructose reduces Tollen's reagent due to enolisation of fructose followed by conversion to aldehyde by base

Glucose and fructose can be distinguished by ninhdrintest

Hydrolysis of sucrose is called esterification
