Its either B or C. Its NOT A and D. I know that for a fact.
Hope this at least sorta helped. Have a good day! :D
you have a picture so i can see it
Answer:
The rate is a mathematical relationship obtained by comparing reaction rate with reactant concentrations.
Answer:
areee....where are the following mate??
S + O → SO -71kcal
Explanation:
The reaction describe is a thermochemical equation. In the reaction above, since heat is liberated, this is an exothermic reaction.
- In an exothermic change heat is liberated to the surroundings.
- At the end of the reaction, the surrounding becomes hotter.
- The value of the heat change is assigned a negative sign.
1 mol of liquid sulfur (S (l)) = S
1 mol of gaseous oxygen (O2 (g)) = O
gaseous sulfur dioxide (SO2) = SO
releasing 71kcal = -71kcal
S + O → SO -71kcal
