Halogen, Fluorine, or bromine
O3 + M2+(aq) + H2O(l) => O2(g) + MO2(s) + 2 H+
Eo(cell) = Eo(O3/O2) - Eo(MO2/M2+)
0.44 = 2.07 - Eo(MO2/M2+)
Eo(MO2/M2+) = 1.59 V
Answer:
In the case of Mount Pinatubo, the result was a measurable cooling of the Earth's surface for a period of almost two years. Because they scatter and absorb incoming sunlight, aerosol particles exert a cooling effect on the Earth's surface.
Explanation:
There are 2 significant figures.
"Rule 3: Trailing zeros are significant if a decimal point is shown in the number, but may or may not be significant if no decimal point is shown."
Answer:
Mg₃N₂ (magnesium nitride)
Explanation:
M(total) = M(mg) + M (n)
M (n) = M(total) - M(mg)
= 0.433g - 0.313g
= 0.12g
mole (N) = 0.12g / 14.0067 g/mol
= 0.008567
mole Mg = 0.313g / 24.3050 g/mol
= 0.012878
Mg = 0.012878 / 0.008567
= 1.5
N = 0.008567 / 0.008567
= 1
multiply by 2 to get whole numbers
Mg = 1.5 × 2 = 3
N = 1 × 2 = 2
Mg₃N₂ (magnesium nitride)
