The correct option is 2.
For a chemical equation to be balanced, the number of atoms of each element present in the reactants must be the same with that present in the products. If the number of atom of any element at any of the two side of the reaction is not the same, then the equation is not balanced. Looking at the options given above, it will be noticed that for option 2, the number of Sr atom at the reactant side is 1 while at the product side it is 2. This shows that the equation is not balanced.

<h3>
What are Isomers ?</h3>
Isomers are compounds which have same empirical formula , same number of atoms are present but they have difference in arrangement if the atoms.
It is given that
There are four cis, trans isomers for 2-isopropyl-5-methylcyclohexanol
the cis, trans designations of the substituents are made relative to the oh group

Answer:
Liming reagent in the given reaction is oxygen.
Explanation:
Mass of octane = 12.85 g
Mass of oxygen = 7.46 g
Molar mass of octane = 114.23 g/mol
Molar mass of oxygen = 32




According to the reaction, 2 moles of octane requires 25 moles of O2
so, 0.1125 moles of octane requires
of oxygen.
but only 0.2331 mol of oxygen is present.
Hence, oxygen is the limiting reagent
<span>The water cycle is like a big circle and doesn’t really have a starting point. There are 4 main stages involved in water cycle i.e. evaporation, condensation, precipitation and runoff, so, I'd say you become water, you evaporate, then you turn into a cloud and rain, then runoff.</span>
