We want: 
S(s) + O2(g) --> SO2(g) 
So the following are the given:
1) S(s) + 3/2O2(g) --> SO3(g) ∆H = -395.8 kJ/mole 
2) 2SO2 + O2 --> 2SO3(g) ∆H = -198.2 kJ/mole 
Reverse Equation 2) and then  divide by 2 
SO3(g) --> SO2(s) + 1/2O2(g) ∆H = +99.1 kJ/mole 
Add Equation 1) 
S(s) + O2(g) --> SO2(g) ∆H = -296.7 kJ/mole

ruslelena [56]

A. both permanent magnets and electromagnets.

Explanation:

A permanent magnet can affect and attract any other permanent magnet and even electromagnet.

They also affect any magnetic materials especially metals that can be magnetized.

In the vicinity of such substances, an attractive or repulsive force sets in and they both interact in the presence of the force field in place.

Permanent magnets cannot magnetize non-magnets.

An electromagnet is a magnet produced by the passage of electric current through a wire wound round a metallic core.
