76.0 mol of P4O10 contains how many moles of P?
2 answers:
Answer : The number of moles of phosphorous are 304 moles.
Explanation :
The formula of given compound is,
In compound, there 4 moles of phosphorus and 10 moles of oxygen.
As we are given that the moles of is 76.0 mole. Now we have to determine the number of moles of phosphorous (P).
As, 1 mole of has 4 moles of phosphorous
So, 76.0 mole of has
of phosphorous
Therefore, the number of moles of phosphorous are 304 moles.

Find the motion diagram attached for the illustration:
Distance is the length of path traveled from the start to the finish. In measuring distance, we wall through the path from start to the finishing point. Distance is a scalar magnitude that has magnitude but no direction.
Displacement is distance that is taken between the start and finishing point. It is a vector quantity that has magnitude and measures direction.
To find the distance;
Distance = 5km + 7km = 12km
Displacement:
Using pythagoras theorem;
Displacement = √7² + 5² = 8.6km
Direction:
sin(bearing ) =
bearing = arcSin 0.5814 = 035.6°
Displacement is 8.6km in a direction 035.6°

The correct answer is <span>a. CaO(s) + H2O(l) Ca(OH)2 (s)
</span><span>Decreasing in entropy means that you have to get a solid from the liquid
</span>therefore : <span>CaO(s) + H2O(l) Ca(OH)2 (s)
This formula will make it absolutely clear
