steps...
1) convert mass H2O to moles H2O
2) use coefficients of balanced equation to convert to moles O2
3) convert moles O2 to L O2.
solution...
10.5 g H2O x (1 mole H2O / 18.0 g H2O) = 0.583 moles H2O
from the balanced equation, 1 mole O2 --> 2 moles H2O.. therefore...
0.583 moles H2O x (1 mole O2 / 2 moles H2O) = 0.292 moles O2
from here you can either use the specific form of the ideal gas law for STP...
0.292 moles O2 x (22.4 L O2 / mole O2) = 6.54 L O2
or you can use the more general form of the ideal gas law...
V = nRT/P = (0.292 moles) x (0.0821 Latm/moleK) x (273 K) / (1 atm)
V = 6.54 L O2
Hope this helps!
Answer:
60.9 metric tons of Mn are accumulated
Explanation:
The Mn accumulates at a rate of 0.06 mgm⁻²day⁻¹.
After 5.0years (5years * 365 = 1825days) will be accumulate:
0.06 mgm⁻²day⁻¹ * 1825 days =
109.5mgm⁻²
Now, 556km² are:
556 km² * ((1000m)² / 1km) = 5.56x10⁸ m²
In 5.56x10⁸ m² you will accumulate:
5.56x10⁸ m² * 109.5mgm⁻² = 6.09x10¹⁰mg are accumulated.
In kg:
6.09x10¹⁰mg * (1kg / 1x10⁶mg) = 6.09x10⁴kg.
In metric tons:
6.09x10⁴kg * (1 metric ton / 1000kg) =
<h3>60.9 metric tons of Mn are accumulated</h3>
The muscles of the body are part of the musculoskeletal system but would not operate without the nervous system providing the impulses that cause the muscles to act. Correct answer: C The nervous system controls all activities within the human body, including the muscles. It sends messages between the brain and the muscles very quickly using nerve impulses (action potentials).
