Answer: The empirical formula is
Explanation:
Mass of Mg= 46.6 g
Mass of S= 61.4 g
Mass of O = 92.0 g
Step 1 : convert given masses into moles.
Moles of Mg =
Moles of S =
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For Mg =
For S=
For O =
The ratio of Mg: S: O = 1: 1: 3
Hence the empirical formula is
A- Drilling through the Earth to reach areas is useful but expensive
Answer:
Explanation:
Sup Wayne I need this answer too.
Answer : The number of moles of ions form are, and there are 3 ions formed.
Explanation :
First we have to calculate the moles of calcium iodide.
Molar mass of calcium iodide = 293.9 g/mol
Mass of calcium iodide = 51.0 g
Now we have to calculate the number of moles of ions.
As we know that when calcium iodide dissolved in water then it dissocites to give calcium ion and iodide ion.
The balanced chemical reaction will be:
From this we conclude that there are 3 ions formed.
As, 1 mole of calcium iodide dissociate to give number of ions
So, 0.174 mole of calcium iodide dissociate to give number of ions
Thus, the number of moles of ions form are,
Subshell S is likely to be filled before the rest of the subshells
