they use oxygen in their breakdown process and at the end of the breakdown they return nutrients like carbon dioxide and nitrogen back to the ecosystem.
<span>D) At point 4, thermal energy from warm air over the land is transferred upward toward cooler areas of the atmosphere.</span>
You would set it up like this…
Actual yield/Theoretical yield x 100
16/24 x 100
The answer is 66.7% or 67%
By definition,
speed = dstance/time.
Note that
1 mile = 1.609 km
Therefore,
1 mile = 1.609 mk
11 minutes = 11/60 h = 0.1833 h
speed = (1.609 km)/(0.1833 h) = 8.78 km/h
Answer: 8.8 km/h (nearest tenth)
Molar mass of iron(III) oxide is 160g/mol
160g ----------- of iron(III) oxide is ---------------- 6.02*10²³molecules
79g ----------- of iron(III) oxide is ---------------- x
x = [6.02*10²³*79g]/160g ≈ <u>2.97*10²³ molecules</u>
