GOOD MORNING:)

HERE IS YOUR ANSWER:--------

ANS ( a) :

THE TEMPERATURE REMAINS CONSTANT DURING STATE OF SUBSTANCE CHANGES THIS IS BECAUSE THE APPLIED ENERGY IS USED BY THE OBJECT TO OVERCOME ITS FORCE OF ATTRACTION.

ANS( B)

WHEN IRON SULPHIDE REACTS WITH DILUTE SULPHURIC ACID U WILL GET IRON SULPHATE ,WATER AND SULPHUR DIOXIDE AS YOUR PRODUCT.

EQUATION:-

FESO4+ H2SO4-----> FE2SO4 + H20.

HOPE THIS HELPS YOU........
