Answer:
Convection occurs in liquids and gases.
Convection transfers thermal energy.
Convection occurs until all of the fluid is at the same temperature.
Explanation:
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise (like gasses), and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Answer:
x = 0.45*28/3 = 4.2 g
Explanation:
showing work
N2 = 28 g/mole
3Mg + N2 → Mg3N2
3moles .. 28 g
0.45 moles .. x
x = 0.45*28/3 = 4.2 g (answer)
