What are the energy transformations in a fossil fuels power plant? to to to :: chemical energy :: electricity :: mechanical energy :: light energy :: thermal energy :: kinetic energy

Please refer to the attached photo. Thank youuu

The following table is the data table recorded in the lab for the reactions listed on in your VCL 3-12. Parameter Reaction 1 Reaction 2 Reaction 3 Mass NaOH 3.9982 3.9958 25.00 25.00 24.99 Initial temperature (°C) 30.05 36.05 30.84 Final temperature (°C) Assuming the experiments are done exactly as describe in VCL 3-12, calculated the energy released, in kJ/mol, of NaOH in each reaction. Show all calculation steps.

Now, in the actual Beirut explosion, 2750. metric tons of ammonium nitrate reacted in the presence of fuel. (1 metric ton = 1 Mg) 11.How many liters of gas were produced? 12.How much heat was released?

If 10g of methane combust completely, find how much energy is released in the reaction given; CH4 + 2O2 --> CO2 + 2H2O, ∆H = - 890kJ

Please calculate the missing energy to complete the complete Born-Haber cycle.(please give the negative sign "-" if your answer is negative; if your answer is positive, do not put the positive sign "+") calculate the missing energy to complete the complete born-haber cycle (please indicate whether negative or positive) *energie de cohesion du réseau ionique = ionic network cohesion energy  *réaction global = global reaction   (please give the missing réaction if it's possible :) with the charges)

DUE NOW, PLEASE ANSWER IT AS SOON AS POSSIBLE. ADDITIONALLY, WOULD YOU MIND TO INCLUDE A SHORT VIDEO TUTORIAL FOR ME ON HOW TO SOLVE THAT ESPECIALLY THE GRAPH PART? PLEASE.

I need help with my chemistry homework

I need the answers for question 11&12

help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working

How much energy(kJ) is released when 3.50 moles of O2(g) react with iron?

This energy diagram is for the thermal decomposition of solid aluminum oxide that yields solid aluminum and oxygen gas.  Write a balanced equation for the reaction.  Explain what feature is shown by the arrow labeled (a) and what it means.  Using chemical symbols and dashed lines (this can be done with type), draw what the activated complex or transition state might look like.  Is this reaction exothermic or endothermic? Explain.
