Question
write the thermochemical equation, given that the heat of reaction qp= -6.1x10^1 kJ when 2.00x10^-3 kg of calcium hydroxide reacts with excess ammonium chloride to produce ammonia(NH3), water and calcium chloride. is this an endothermic or exothermic reaction? using thermochemical equation calculate the value of q if 10.0 g of ammonia were to react with and and ammonium chloride. is this reaction endothermic or exothermic? write the thermochemical equation, given that the heat of reaction qp= -6.1x10^1 kJ when 2.00x10^-3 kg of calcium hydroxide reacts with excess ammonium chloride to produce ammonia(NH3), water and calcium chloride. is this an endothermic or exothermic reaction? using thermochemical equation calculate the value of q if 10.0 g of ammonia were to react with and and ammonium chloride. is this reaction endothermic or exothermic? write the thermochemical equation, given that the heat of reaction qp= -6.1x10^1 kJ when 2.00x10^-3 kg of calcium hydroxide reacts with excess ammonium chloride to produce ammonia(NH3), water and calcium chloride. is this an endothermic or exothermic reaction? using thermochemical equation calculate the value of q if 10.0 g of ammonia were to react with and and ammonium chloride. is this reaction endothermic or exothermic?Explanation / Answer
Ca(OH)2 + 2NH4Cl ----------------------->2 NH3 + CaCl2 + 2 H2O
it is endothermic reaction .
Qp value is negative that means deltaH value positive . so it is endothermic reaction.
Ca(OH)2 mass = 2 x 10^-3 kg = 2 g
for 2 g ------------------------> 6.1 heat
for 10 g --------------------> x
x = 6.1 x 10 / 2
= 30.5
q value = -30.5 kJ
it is endothermic
