The answer is B :) hope this helped at least
Answer:
Explanation:
Free radicals unstable atoms because it can cause damage cells, as well as causing illness and aging, which means that it can cause harm into our bodies because it damages the DNA and the lipids which is also known as fatty acids
Answer:
[CO] = 0.078M
[Cl2] = 0.078M
[COCl2] = 0.477M
Explanation:
Based on the reaction:
CO(g) Cl2(g) ⇄ COCl2(g)
<em>Where equilibrium constant, kc, is:</em>
kc = 77.5 = [COCl2] / [CO] [Cl2]
[] represents the equilibrium concentration of each gas. The initial concentration of each gas is:
[CO] = 0.555mol/1.00L = 0.555M
[Cl2] = 0.555M
And equilibrium concentrations are:
[CO] = 0.555M - x
[Cl2] = 0.555M - x
[COCl2] = x
<em>Where x is reaction coordinate</em>
Replacing in kc expression:
77.5 = [x] / [0.555M - x] [0.555M - x]
77.5 = x / 0.308025 - 1.11 x + x²
23.8719 - 86.025 x + 77.5 x² = x
23.8719 - 87.025 x + 77.5 x² = 0
x = 0.477M. Right answer
x = 0.646M. False answer. Produce negative concentrations
Replacing:
<h3>[CO] = 0.555M - 0.477M = 0.078M</h3><h3>[Cl2] = 0.078M</h3><h3>[COCl2] = 0.477M</h3>
And those concentrations are the equilibrium concentrations
The question is: Give the systematic name of 
.
Answer: The systematic name of is diphosphorus trisulfide.
Explanation:
As the chemical formula of given compound is . This sows that there are two phosphorus atoms so a prefix "di" will be added before the name of phosphorus atom.
Whereas there are three sulfur atoms present here. So, a prefix "tri" will be added before naming the sulfur atom. As sulfur is the anion so a suffix '-ide' will be added to its name.
Hence, name of the compound is diphosphorus trisulfide.
Thus, we can conclude that the systematic name of is diphosphorus trisulfide.
