Answer:
O
Explanation:
oxygen is the most electronegative so it has the most attraction :)
Answer:
The grams of MgCl₂ that are needed are 63.1 g
Explanation:
First of all, try to think the equation and ballance it. This is it:
3MgCl₂ + 2Na₃PO₄ → Mg₃(PO₄)₂ + 6NaCl
Let's convert our f.u in mol
1 mol = 6.02x10²³ formula units (Avogadro's number)
So f.u / Avogadro = mol
1.33x10²³ / 6.02x10²³ = 0.221 moles.
So 1 mol of phosphate sodium comes from 3 mol of magnesium chloride.
How many mol of magnesium chloride are necessary, for 0.221 mol of phosphate.?
0.221 moles .3 = 0.663 moles.
Molar mass of MgCl₂ is 95.2 g/m
0.663 moles . 95.2 g/m = 63.1 g
I will list them from alkaline with the lowest boiling point and alkaline with the highest.
1. C2H6
2. C9H20
3. C11H24
4. C16H34
5. C20H42
6. C32H66
7. C150H302
I have taken a quiz similar to this before and can assure you this is correct and is primarily because of the number of Carbons and Hydrogens within this. More Carbons and Hydrogens causes Boiling Points to increase because of stronger bonds.
