So, personally, I think it's not that safe to live right by a nuclear plant because it contains radioactive energy and that is unhealthy to the human body. Living by one a person should also take the precautions that it could have a malfunction and that could cause a fatal accident, an explosion. With that radioactive energy is released and both ruins the area and destroys everything. Well my answer is not that great but I hope this helps.
The reaction equation is:
Li + Br → LiBr
39 grams of Li = 39 / 7 = 5.57 moles of lithium
41.5 grams of Br = 41.5 / 80 = 0.52 mole of bromine
Answer:
A. Polar regions receive less solar energy and heat per unit area than tropical regions.
Explanation:
The sun is lower in the sky the farther away from the equator you go (at higher latitudes), so the solar energy is less direct. Climate in areas with less direct solar input tends to be generally cooler.
Answer:
The answer to your question is: Molecular formula = C₁₈H₂₄O₂
Explanation:
Estradiol
C = 79.37 %
H = 8.88 %
O = 11.75 %
Molar mass = 272.37
Process
Carbon = 79.37 g
Hydrogen = 8.88 g
Oxygen = 11.75 g
12 g of Carbon ----------------- 1 mol
79.37 g ---------------- x
x = (79.37 x 1) / 12
x = 6.61 mol
1 g of Hydrogen ---------------- 1 mol
8.88 g ---------------- x
x = (8.88 x 1 ) / 1
x = 8.88 mol
16 g of Oxygen ------------------ 1 mol
11.75 g ----------------- x
x = (11.75 x 1) / 16
x = 0.73
Divide by the lowest number of moles
Carbon = 6.61 / 0.72 = 9.2
Hydrogen = 8.88 / 0.73 = 12.2
Oxygen = 0.73/0.73 = 1
Empirical formula
C₉H₁₂O₁
MW of the empirical formula = (12 x 9) + (12 x 1) + (16 x 1)
= 136 g
Divide molar mass of estradiol by the molar mass of the empirical formula.
= 272 / 136
= 2
Then the molecular formula is:
2(C₉H₁₂O) = C₁₈H₂₄O₂
