Answer:
Temperature, mass, and the type of material are factors that affect the thermal energy of an object.
Material with the higher specific heat will have more thermal energy than material with lower specific heat if they both have the same mass and temperature.
<h3><u>Answer;</u></h3>
1) 2H2(g)+O2(g)⟶Δ2H2O(g)+483.6kJ - Exothermic
2) 6CO2(g)+6H2O(l)+15000kJ⟶C6H12O6(aq)+6O2(g) - Exothermic
3) 2Al(s)+Fe2O3(s)⟶Al2O3(s)+2Fe(s)+850kJ - Exothermic
<h3><u>Explanation</u>;</h3>
- Exothermic Reaction is a chemical reaction in which heat is given out is known as exothermic reaction, while, and endothermic Reaction is a chemical reaction in which heat energy is absorbed is known as endothermic reaction.
- The reaction between carbon dioxide and water is an example of an exothermic reaction. When most gases dissolve in solution, the process is exothermic meaning that heat is released as the gas dissolves
- The reduction of ferric oxide by aluminium is highly exothermic and therefore the iron formed will be in the molten state.
It is known as a group
