Answer:
C) Temperature and Kinetic Energy.
Explanation:
Hello there!
In this case, according to the generic heating curve on the attached file, it possible to see that on the point C, whereas the line is diagonal, the temperature increases, but also the kinetic energy increases because the molecules gain energy due to the increase of the temperature. It is important to say that on flat lines, like those on B and D, the phase change takes place and just the potential energy change.
In such a way, we infer that the answer is C) Temperature and Kinetic Energy.
Best regards!

<h3>Known</h3>
Mass = 32grams
Name of atom = Methane (CH4)
Molar mass C = 12
Molar mass H = 1

<h3>Question</h3>
molecules (mol?)
════════════════════
<h3>Way to do</h3>
mass = mol × molar mass
32g = mol × (CH4)
33g = mol × (12 + (4×1))
32g = mol × 16
mol = 32 : 16
mol = 2

#Ey tell me if its mol or total particles
Answer:
pretty sure they're called groups
Fe3N2, also known as Iron (II) nitride, is an ionic compound.
Ionic compounds are compounds that consists of metals and non-metals bonded with ionic bonds. The metal ion gives up electron(s) to the non-metals.
Since iron is a metal and nitrogen is an non-metal, the bond they would form would be an ionic bond. Iron gives up 2 electrons to form iron(II) ion, while nitrogen gains 3 electrons to form nitride ion. Since one iron cannot let a nitrogen gain 3 electrons, so in the compound, there would be 3 iron (ii) ions that has given up 6 electrons in total while 2 nitride ions have gained 6 electrons in total.
