The controlled variable, I think.
<span>The old car left on the side of the road showed signs of corrosion. We call this common chemical reaction rusting. The equation for this reaction can be written as 4Fe + 3O2 → 2Fe2O3. What are the reactants in the rusting process?

C. Iron and Oxygen
Carbon disulfide is prepared by heating sulfur and charcoal. the chemical equation is S2(g) + C(s) <---> CS2 (g) Kc = 9.40 at 900 K.
Hope this helps:)
Answer: D. Amount of substance present in Avogadro‘s number of particles of the substance
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP, contains avogadro's number
of particles and weighs equal to the molecular mass of that substance.
A mole is defined as the amount of substance that contains Avogardro number of the substance. Avogadro's number is given by
.
particles
The fourth combination is not allowed.
The third quantum number, i.e. m subscript l, only may an integer number from -l to + l. Given that l = 0, the only allowed m subscript l is 0.
