Given the equation i2(s) + 62.4kj --> i2(g), which of the following is true: a) the reaction is exothermic b) h= +62.4kj c) h= -62.4kj d) the reaction releases heat

The statements that are true are that;
The reaction is exothermic;
H = -62.4 kJ
And also the reaction releases energy.
Exothermic reactions are chemical reactions that release energy to the environment to the environment causing the reaction mixture and the surroundings become more hotter; therefore the delta H is negative since the heat of the products is less that that of the reactants. 

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab. 

Where are the following questions
