Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Hey there!
Get molar mass of C₆H₁₀S:
C: 6 x 12.01
H: 10 x 1.008
S: 1 x 32.065
------------------
144.205 g
To find the amount of moles we have, divide 22.4 by 144.205. Get 0.155.
There are 0.155 moles of S.
Hope this helps!
This is an example of competition because the plant is releasing the chemical in order to kill off the other nearby plants that may be competing and fighting for the water and nutrients in the soil in order to survive. The plant species releasing the chemical will kill the nearby plants, rather than benefit them. Therefore, it cannot be mutualism. The plant species is also not working together with the nearby plants by killing them. It also cannot be cooperation or working together.
Answer:
a. N₂(g) + O₂(g) → 2 NO(g)
b. 2 HgO(s) → 2 Hg(l) + O₂(g)
c. 4 Fe(s) + 3 O₂(g) → 2 Fe₂O₃(s)
d. 2 Na(s) + Cl2(g) → 2 NaCl(s)
e. 2 Cu₂O(s) + O₂(g) → 4 CuO(s)
Hope this helps.
