water stored in a dam
Explanation:
when the water is in dam it is ready to move bit is not moving
Answer:
The answer to your question is: ΔHrxm = -23.9 kJ
Explanation:
Data:
2Fe(s)+3/2O2(g)→Fe2O3(s), ΔH = -824.2 kJ (1)
CO(g)+1/2O2(g)→CO2(g) ΔH = -282.7 kJ (2)
Reaction:
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
We invert (1) and change the sign of ΔH
Fe2O3(s) → 2Fe(s)+3/2O2(g) ΔH = 824.2 kJ
We multiply (2) by 3
3( CO(g)+1/2O2(g)→CO2(g) ΔH = -282.7 kJ) (2)
3CO(g)+3/2O2(g)→3CO2(g) ΔH = -848.1 kJ
We add (1) and (2)
Fe2O3(s) → 2Fe(s)+3/2O2(g) ΔH = 824.2 kJ
3CO(g)+3/2O2(g)→3CO2(g) ΔH = -848.1 kJ
Fe2O3(s) + 3CO(g)+3/2O2(g) → 2Fe(s)+3/2O2 + 3CO2(g)
Simplify
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g) and ΔHrxm = -23.9 kJ
Answer:anions with least precipitates are anions of salt produce by a strong acid and strong base e.g KCL,Na2SO4,
Explanation: salts produce from strong acid such as HCL and a strong base such as KOH are extremely soluble and hence produce little or no precipitate when dissolved in water .meaning the salt are highly soluble , most group1 elements form salts that are highly soluble and hardly precipitates e.g Na(sodium) pottasium(K) ,lithium(Li)salts.they are called alkaline metals.
B) exception to the rules are hydrogen and Rubidium.hydrogen because it occurs basically as a gas and forms H^+ which tend to form a hydrogen bond while rubidium is a heavy metal forming insoluble salt
