How to Build Healthy Interpersonal Relationship Human beings are social creatures and thrive(茁壮成长) in relationships with others. A healthy part to be a well-rounded, happy individual is engaging in healthy relationships with others. These friendships can provide safe environments in which individuals can thrive and help promote general well-being. _36__ 1. Know your worth. One of the first steps in building healthy interpersonal relationships is understanding one’s value. When an individual is aware of and treasures what he or she has, the building of relationships can be f联氨(N2H4)及其衍生物是一类重要的火箭燃料。N2H4与N2O4反应能放出大量的热。 (1)已知:2NO2(g)==N2O4(g) △H=-57.20kJ·mol-1。一定温度下,在密闭容器中反应2NO2(g)N2O4(g)达到平衡。 其他条件不变时,下列措施能提高NO2转化率的是__________(填序号) A.减小NO2的浓度 B.降低温度 C.增加NO2的浓度 D.升高温度 (2)25℃时,1.00gN2H4(l)与足量N2O4(l)完全反应生成N2(g)和H2O(l),放出19.14kJ的热量。则反应2N2H4(l)+N2O4(l)=3N2(g)+4H2O(l)的△H=____________kJ·mol-1 (3)17℃、1.01×105Pa,密闭容器中N2O4和NO2的混合气体达到平衡时,c(NO2)=0.0300mol·L-1、c(N2O4)=0.0120mol·L-1。计算反应2NO2(g)N2O4(g)的平衡常数K。 (4)现用一定量的Cu与足量的浓HNO3反应,制得1.00L已达到平衡的N2H4和NO2的混合气体(17℃、1.01×105Pa),理论上至少需消耗Cu多少克?
