The correct answer is D 4.29x10^24
Has only 7 electrons so it want to bond with other elements so its very reactive and unstable. Hope this helps
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
The molarity of the solution is equal to 0.500M.
<h3>Mole calculation</h3>
To calculate the molarity of a solution, one must use the value of the amount of moles and the volume, so that:
So, applying the values given in the question we have:
So, the molarity of the solution is equal to 0.500M.
