Answer:
1552.83J Released
Explanation:
1. mass/m=225
Initial temp:86C, final:32.5C
Changed Temp: 32.5-86= -53.5C
s=0.129 J/gC
Formula: q= m times s times changed Temp.
q=(225)(0.129)(-53.5)
q= -1552.83 J
q=1552.83 J Released
Answer:
Iodine molecules containing two atoms of iodine (I2) each are non-polar. That is because when iodine bonds with another iodine atom they attract electrons and share them equally. Thus neither water nor potassium permanganate dissolves in hexane.
