Answer:
12.78
Explanation:
pOH= -log(0.0600) = 1.22184875
pH= 14-1.22184875 = 12.78
The time take for the train to travel 950 Km is 7.92 h
<h3>What is speed? </h3>
Speed is the distance travelled per unit. Mathematically, it can be expressed as:
Speed = distance / time
With the above formula, we can determine the time. Details below:
<h3>How to determine the time</h3>
The time taken for the train t travel 950 Km can be obtained as follow:
- Speed = 120 Km/h
- Distance = 950 Km
- Time =?
Speed = distance / time
120= 950 / time
Cross multiply
120 × time = 950
Divide both side by 120
Time = 950 / 120
Time = 7.92 h

I don’t know if I’m right I’m taking a guess but isn’t it because energy comes from the sun and we can’t change the sun
This problem can be solved directly using stoichiometry.
We can actually see that for every mol of P4O10, there are 4 moles of P.
Therefore the total moles of P is:
moles P = 88.5 moles P4O10 * (4 moles P / 1 mole P4O10)
<span>moles P = 354 moles P</span>
