Under normal conditions, atoms have a positive charge.
Hope that helped ^^
M<span>olar mass Hg = 200.5920g/mol </span>
<span>Hg = 24.1/200.5920 = 0.120mol </span>
<span>234.32K liquid to 25C (298.15K) liquid </span>
<span>h = (0.120)(28.0)(298.15 - 234.32) = 214.4688 J </span>
<span>234.32K liquid to 234.32K solid </span>
<span>h = (0.120)(2.29) = 0.2748 kj </span>
<span>total heat = 0.2145 + 0.2748 = 0.4893 kJ</span>
Usually the controlled experiment is the one that is not tested so they look at the experimental experiment to find the differences. Sorry if this doesn't answer your question.
Answer:
7.462
Explanation:
Well, every time that the tempurature is increased, the atmspheric pressure is increased by 0.574%. This would then mean that you would have 0.574 times
13. That would then equal 7.462. I hope this helps.
Answer: Lost 3 electrons
Explanation:
Ions are postively or negatively charged atom. The postively charged are called cations while the negativity charged are called anions.
Atom becomes positively charged by losing electrons while negatively charged by gaining electrons.
So, the +3 ion means it has lost 3 electrons
