The answer would be 6.20 so they would be equivalent
Answer:
18.45 g of C
Explanation:
This is a problem of rules of three:
1 mol of C₃H₈ contains 3 moles of C and 8 moles of H
If 8 moles of H are contained in 1 mol of propane
4.10 moles of H are contained in (4.1 . 1) /8 = 0.5125 moles
Now, If 1 mol of propane contains 3 moles of C
0.5125 moles of propane may contain (0.5125 . 3) / 1 = 1.5375 moles of C
Let's convert the moles to mass:
1.5375 mol . 12 g /mol = 18.45 g
Answer:
K < Mg < P < O
Explanation:
The trend for electronegativity is that it increases as you go up and to the right of the periodic table. If we look at the periodic table, O is more to the right and up of P and the other elements. Then we see that P is more up and right to the other elements. Then we see that Mg is more up and to the right of K. So we get the order of K < Mg < P < O. Hope this helps!
