Answer:
Ranked from lowest to highest:
Sulfur - 999.6 kJ/mol
Hydrogen - 13.5984 kJ/mol
Oxygen - 13.6181 kJ/mol
Fluorine - 17.4228 kJ/mol
KBr + H2O = KOH + Br2 + H2
So we know that we need a 2 on the left of kbr so it would equal the right Br.
=2KBr
now put a 2 in front of KOH since we need a 2k on right side
Now we put a 2 infront of H2O which wil make 4 h's and 2 o's
2h2o
now it is balanced
2KBr + 2H2O = 2KOH + Br2 + H2
Answer:
Only Reaction 1
Explanation:
In reaction 1, there is a change in state from solid to liquid. Hence, there is an increase in number of ways particles and their energies could be arranged. As a result, entropy increases.
In reaction 2, there is a decrease in amount of gas particles (4 mol to 2 mol). Hence there is a decrease in the number of ways particles and their energies could be arranged. As a result entropy decreases
