Answer:
higher costs, energy use and carbon emissions
Explanation:
not sure if this is right or not, I apologize if this is wrong
The answer is c. Calorimeter
<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.
Answer:
1) Combustion
2)Synthesis
3)Single Replacement
4)Decomposition
5)Double Replacement
6)Synthesis
7)Double Replacement
8)Single Replacement
9)Combustion
10)Decomposition
Explanation:
Remeber, decomposisition is breaking things apart, synthesis is building them, cobusion will always make water and CO2 and will always burn O2, single replacemnt will have 1 thing replaced (single) and double replacement will have 2 things replaced (double).
Hope this helps!
D i hope it helps i not that smart
