The number of moles present in the FeSO4 are 0.055 mol.
<u>Explanation:</u>
- The mass of a substance containing the same number atoms in 12.0 g of 12C is known as mole. One mole of any substance is equal to 6.023 x 10^23. The moles of a substance can be determined by using the formula,
Number of moles = mass in grams / molecular mass
Given,
mass = 8.36 g,
molecular mass of FeSO4 = 151.908 g / mol
number of moles = 8.36 / 151.908
= 0.055 mol.
In collecting the precipitate, it is inappropriate to heat <span>the reacted mixture and evaporate off the water because it is possible that the mixture contains other substances that precipitates as well when the mixture is being heated so you will not be able to collect what you want.</span>
Answer:
Iodine has more electron levels (rings) than fluorine.
Explanation:
On the periodic table, fluorine is on period 2 so it has 2 outer rings, iodine is on period 5 so it has 5 outer rings. The more rings the higher radius.
The balanced chemical formula would be:
2Mg + O2 = Mg2O2
