MC₂H₄O₂ = 2 * 12 g/mol + 4 * 1 g/mol + 2 * 16 g/mol = 60 g/mol
c = 0.5 mol/L
V = 1 L
n = c * V
n = 0.5 mol/L * 1 L = 0.5 mol
m = n * M
m = 0.5 mol * 60 g/mol = 30 g/mol
answer E
(-_-(-_-)-_-)
Answer:
C) 7 to 1
Explanation:
The periodic trend of Atomic Radii for the Periodic Table of Elements is down and to the left the atomic radii increases.
So, from period 1 to 7 and group 18 to group 1, the atomic radii increases.
The opposite (decreasing) would be from period 7 to 1 and group 1 to group 18.
Therefore, our answer is C.
The first one is right and so is eight you have to add them together to see if they go together if they dont add what is missing
Cl, because a higher electronegativity indicates that the atom attracts more electrons.
Examples: phosphorus trichloride
( PCl3)
Phosphorus trioxide
( P2O3)
