When 5.0 mL of a 1.0 M HCl solution is mixed with 5.0 mL of a 0.1 M NaOH solution, temperature of solution is increased by `2^@C` predicted accurately from this observation?

A

If `5mL` of `0.1M HCl` is mixed with `5mL 0.1M NH_(3)` solution, the temperature rise will be less than `t^(@)C`

B

If `5mL 0.1M CH_(3)COOH` is mixed with `5mL 0.1 M NaOH`, the temperature rise will be less than `t^(@)C`

C

If `10mL` of `1.0M HCl` is mixed with `10mL` of `0.1M NaoH`, the temperature rise will be `2t^(@)C`

D

If `10 ML` of `0.1M HCl` is mixed with `10 mL` of `0.1 M NaCl` the temperature rise will be `t^(@)C`
