Answer:
The thermal energy released per gram is 19.2 kJ/g.
(3) is correct option.
Explanation:
Given that,
Weight of hydrocarbon = 2.50 g
Heat capacity
We need to calculate the thermal energy released
Using formula of thermal energy
Heat released =heat absorb by calorimeter+heat absorb by water

Put the value into the formula


Now, The thermal energy released per gram

Put the value into the formula


Hence, The thermal energy released per gram is 19.2 kJ/g.
The similarity between electric field and magnetic field is that both fields attract or repel charges in the field.
<h3>What is electric field?</h3>
An electric field is a region of space that surrounds electrically charged particles and exerts force on other charged particles within the filed.
