Calculating Heat of Reaction in Thermochemistry Problems

In summary, thermochemistry is the study of heat energy involved in chemical reactions and processes, focusing on the relationship between heat, energy, and chemical reactions. It is considered difficult due to its complex mathematical calculations, the need for a strong understanding of concepts such as thermodynamics and heat transfer, and the use of equations and formulas. Common challenges include interpreting data, understanding equations, and comprehending the abstract nature of the subject. To improve understanding, regular practice, working on real-life examples, and seeking help from a tutor or study group are recommended. Potential career opportunities in thermochemistry include roles in chemical engineering, materials science, research, and industries such as energy production, pharmaceuticals, and environmental science.

I am a high school senior having a problem with a problem in my thermochem class. Could someone please help me understand the following:

if 16.8 kJ are released when 1.20 g of F sub 2 (F2) reacts with SiHsub4 (SiH4), what is the heat of reaction when 1.90 moles of Fsub2 react?

Nothing hard here - convert 1.2g to moles and calculate heat evolving per mole, then use this value to calculate amount of heat released when 1.90 moles react.
