Answer:
Zr
Explanation:
The balance equation of the reaction is:
Zr + 2 H₂O ⇒ ZrO₂ + 2 H₂
Being:
- Zr: 91 g/mole
- H: 1 g/mole
- O: 16 g/mole
the molar mass of the reactants participating in the reaction are:
- Zr: 91 g/mole
- H₂O: 2*1 g/mole + 16 g/mole= 18 g/mole
If by stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction) they react in moles:
then by stoichiometry the following quantity of mass react:
- Zr: 1 mole*91 g/mole= 91 g
- H₂O: 2 moles*18 g/mole= 36 g
Now the following rule of three applies: if 91 g of Zr react with 36 g of H₂O, 4500 g of Zr with how much mass of H₂O would it react?

mass of H₂O= 1,780 grams
But 1780 grams of H₂0 are not available, 1.5 * 10⁴(15,000) grams are available. Since it has more mass than it needs to react with 4500 grams of Zr, Zr zirconia will be the limiting reagent.

The Kuiper belt is home to three officially recognized dwarf planets: Pluto, Haumea, and Makemake. Some of the Solar System's moons, such as Neptune's Triton and Saturn's Phoebe, are also thought to have originated in the region.
