Answer:
Reaction 1 = -462.5 kJ/mol
Reaction 2 = -572 kJ/mol
Magnesium combustion = -601.83 kJ/mol
Answer:
I think it's because it shows properties that are similar to noble gases.
2KMno4+16hcl=2kcl+2mncl2+8h2o+5cl2
Answer:
HCl(aq) + KOH(aq) —> KCl(aq) + H2O(l)
Explanation:
Aqueous solution of HCl and aqueous solution of KOH react as follow:
HCl(aq) + KOH(aq) —>
In solution, HCl and KOH will dissociates as follow:
HCl —> H+ + Cl-
KOH —> K+ + OH-
During the reaction, a double displacement reaction occur as shown below:
H+ + Cl- + K+ + OH- —> K+Cl- + H+OH-
The elemental equation is given below:
HCl(aq) + KOH(aq) —> KCl(aq) + H2O(l)
