Explanation:
By placing the jar under hot water, metal lid molecules expanded from heat which caused it loosen up. However, there can be a possibility where the jar lid was stuck because of the stickiness of the pickle juice which later got washed off or melted after placing the jar under hot water.
Um this is what I got
<span>a. NH4NO3 -------------> N2O + 2 H2O This is the correct equation ammonium nitrate does not produce oxygen when heated.
If you meant ammonium nitrite, not nitrate, in which case the equation is:
NH4NO2 ---------------> N2 + 2 H2O, but this doesn't produce oxygen either. If you teacher is ignorant of these facts, or gave you a bogus problem to solve, then use this equation (even though it doesn't exist): 2 NH4NO3 ----------------> 2 N2 + O2 + 4 H2O (Drax an "x' through the yields line to indicate that this reaction actually doesn't take place.
b. 2 NaHCO3 + H2SO4 --------------> Na2SO4 + 2 CO2 + 2 H2O
c. PCl5 + 4 H2O ---------> H3PO4 + 5 HCl </span>
Hope this helped!
