Answer:
25.8
Explanation:
Let's write the reaction between magnesium-phosphide and potassium:
Mg3P2 + K = Mg + K3P
And now let's balance this equation:
Mg3P2+6K=3Mg+2K3P
We see that the ratio of magnesium-phosphide and potassium is 1:6, which means that for every mole of magnesium-phosphide there need to be 6 moles of potassium.
Since we have 4.3 moles of Mg3P2, there need to be 6 • 4.3 = 25.8 moles of potassium.

Answer:
due to the overlaying layers of strata (layers of earth) an high pressure is created at the core. due to this it behaves like an solid rether than being a liquid... the lower mantle is not solid because in this case the overlaying strata doesn't produce that much pressure on it..

The right answer is 271.78 degrees for cyclohexane.
For each liquid there is a precise relationship between pressure and boiling temperature, we can define the boiling temperature as the moment when the first bubble of vapor appears on the surface of a liquid.
