Answer:
Blue
Explanation:
If you look at a flame, blue is always at the bottom right? So that would be common sense that blue would be the hottest.
The molarity is a concentration unit which defined as the number of moles of solute divided by the number of liters of solution. So the molarity of the solution is 3/2=1.5 mol/L.
Answer:
a. in supernovae and star collisions
Explanation:
The periodical table contains some heavier elements, which are formed as neutron stars pairs hit eachother and erupt cataclysmically.
The star emitts very large quantities of energy and neutrons during supernova, which allow for the production of heavier elements than iron, such as uranium and gold. All these elements are ejected into space during the supernova explosion.

Answer:
The mass of Mg consumed is 23.76 g.
Explanation:
Magnesium and nitrogen react as : three moles of magnesium reacts with one mole of nitrogen to give one mole of magnesium nitride.
as given that the mass of nitrogen reacted = 9.27 g
moles of nitrogen reacted = 
Thus moles of magnesium reacted = 3 X 0.33 = 0.99 moles
mass of Mg reacted = moles X atomic mass = 0.99 X 24 = 23.76 grams
