We first calculate the decay constant, λ
λ = ln(2) / half life
λ = ln(2) / 14.3
The decay equation is:
N = N(initial) x exp(-λt)
N = 4 x exp(-ln(2)/14.3 x 71.5)
N = 0.125 mg will remain
Two atoms hold together in a molecule are the electric and nuclear force
<span>7.86 g / 1 mL
divide g by 1000 for kg and divide mL by 100 for dL
</span>0.00786 kg / 0.01 dL = 0.786 kg/dL (density)
3.67 kg / 0.786 dL = 4.6692 dL
Another approach:
3.67kg > (3.67kg x 1000) = 3670 grams
3670 grams / 7.86 (density) = 466.92 mL
466.92 mL (divide by 100 for dl) = 4.6692 dL
Answer:
A hurricane,tornado,wind, rain.
Explanation:
Those are examples of a natural process which impact and ecosystem.
Depression is freezing point is a colligative property. It is mathematically expressed as ΔTf = Kf X m
where Kf = <span>freezing point depression constant = 1.86°c kg /mol (for water)
m = molality of solution = 1.40 m
</span>∴ ΔTf = Kf X m = 1.86 X 1.40 = 2.604 oC
Now, for water freezing point = 0 oC
∴Freezing point of solution = -2.604 oC
