Answer:
[Fe(NO₃)₃] = 0.90 M
Explanation:
Molarity = Mol/L
Total volume of solution: 31.65 mL + 44.96 mL = 76.61 mL
Let's determine the moles of salt ([M] . volume)
0.03165 L . 1.07M = 0.0338 moles
0.04496L . 0.79M = 0.0355 moles
Total moles Fe(NO₃)₃ = 0.0338 + 0.0355 = 0.0693 moles
Volume of solution = 76.61 mL = 0.07661 L
0.0693 mol / 0.07661 L = 0.90 mol/L
Answer: Noble gas configuration is the ionisation of valence electrons using the octet rules.
Explanation:
Noble gases are the halogen, iodine etc. they form molecules using anion valence electrons in order build octet structures.
A scientist adds heat to each of the following substances.The one that<span> will probably absorb the most heat before its temperature changes significantly is
</span> 50 g of liquid water
because water has larger heat capacity
so correct option is C
