They have you the equation and everything to plug in. You barely have to do anything here, I’m unsure why you’re even asking.
Force = mass*acceleration
20N = 10kg*a
a = 2 m/s^2
It will melt or the molecules inside of it will get hot
1.5 moles of
gas
Reaction of Al with
to form
is given below...
2 Al + 1.5
→ ![Al_{2} O_{3}](https://tex.z-dn.net/?f=Al_%7B2%7D%20O_%7B3%7D)
Here, 2 moles of Aluminum reacts with 1.5 moles of
atomic weight of aluminum = 27 g / mole
so, 1 mole of aluminum contains 27 g
then how many moles are there if it has 54 g in it.
moles of aluminum in 54 g = 54/27 = 2 moles
As per the equation mentioned above,
2 moles of aluminum reacts with 1.5 moles of
.
∴1.5 moles of oxygen gas (02) are needed to completely react with 54.0 g of aluminum.

Absolutely false. If it all have the same average kinetic energy, the substance will not change in state. Hence, it is absolutely false. Go to Google and search for heating curve. When you analyse the curve, the line which is horizontally straight is where the average kinetic energy remains constant. The other lines represent the increase in kinetic energy. So as heat is continued supplying, the substance at some point will increase kinetic energy.
The answer is b: in the oscillating electric and magnetic fields
