First convert to moles:
0.5113 g / 17 g/mol = 0.0301 mol
Now create a ratio based on the reaction provided to solve for the unknown:
4 NH3 / -905.4 kJ = 0.0301 mol NH3 / x kJ
x = -6.808 kJ
Answer: C
There are 2 or more different type of atoms within a molecule
Answer: potential.
Chemical energy is the energy provided by a chemical reaction.
Kinetic energy is the energy due to the speed.
Potential energy is the energy due to the position. For example, an object on the top of a mountain, has the possibility to perform work if it falls.
Electromagnetic energy. is propagated by waves: radio waves, infrared radiation, microwaves, etc.
I am almost positive that the answer is: Plasmas. Let me know if im right or not please!! :)
Answer:
=10 joules
when multiplying with newtons ( the unit of force)
by a perimeter, it will becone joules, but the specific amount depends on how many newtons and metres there are
