Answer:
The process that converts a solid mcompound into a gas is sublimation.
E.g- dry ice, solid iodine and ammonium salts
when the above solid are heated, only particles which are found on the surface of the solid gain enough energy and break all forces of attraction and form a gas.
Explanation:
Answer:
∆H = negative and ∆S = positive.
Explanation:
The reaction given in the question is spontaneous at room temperature ,
hence ,
The the gibbs free energy , i.e. ,∆G will be negative for spontaneous reaction
According to the formula ,
∆G = ∆H -T∆S
The value of ∆G can be negative , if ∆H has a negative value and ∆S has a positive value , because , T∆S , has a negative sign .
Hence , the answer will be , ∆H = negative and ∆S = positive.
reactants because it had other chemicals, when more are mixed it will be more stronger.
It is the correct answer
