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.
A is the correct answer
groups are the vertical columns on the table. if you look at it, you can see that the atomic number and atomic mass increases as you go down.
Answer: Temperature will Increase
PV=nRT. Ideal Gas Law
We see by inspection of the ideal gas law, there is a liner relationship between Pressure and Temperature of an ideal gas. So if the pressure is increased on the gas, then the Temperature will increase also.
Any questions please feel free to ask. Thanks and have a great day!
It does not affect the mass, it only affects the outwards appearance of the ice/water.
