You're looking for the number of moles of H2, and you have 6.0 mol Al and 13 mol HCL.
For the first part, you have to make your way from 6.0 mol of Al to mol of H2, right? For that to happen, you need to make a conversion factor that will cancel the mol Al, in such case use the 2 moles of Al from your equation to cancel them out. At the top of the equation, you can use the number of moles of H2 from the equation and find the moles that will be produced for the H2.
6.0mol Al x 3 mol H2/2 mol Al = 9 mol H2
For the second part, you have to make the same procedure, make a conversion factor that will cancel the mol of HCL and for that you need to use the 6 mol HCL from your equation, and at the numerator you can put the 3 mol of H2 from the equation so that you can find the number of moles of H2 that will be produced.
13 mol HCL x 3 mol H2/6 mol HCL = 6.5 mol H2
As it can be seen, HCL produces the less amount of H2 moles. Therefore, the reaction CANNOT produce more than 6.5 mol H2, in that case 6.5 mol will be the maximum number of moles that will be produced at the end because HCL does not have enough to produce more than 6.5 mol.
In that case HCL is the limiting reactant because it limits that will be produced, and so the answer is B!
Applications of iron oxide nanoparticles include terabit magnetic storage devices, catalysis, sensors, superparamagnetic relaxometry (SPMR), and high-sensitivity biomolecular magnetic resonance imaging (MRI) for medical diagnosis and therapeutics.
Answer: Option (c) is the correct answer.
Explanation:
A monomial is defined as an algebraic expression in which there is only one term present.
For example, 3x is a monomial.
A binomial is defined as an expression where there will be two terms present. For example, 
is a binomial.
A polynomial is defined as an algebraic expression which contains more than two terms.
For example, 
is a polynomial.
Thus, we can conclude that the given expression is a polynomial.
Answer:
I'm rly confused but Si stands for silicon in the compound if that's what ur asking
hope it helps tho
Answer:
1. CBr4
2. C5H12
3. CF4
4. C8H17NH2
Explanation:
1. The boiling point of a molecule depends on its structure. Because the boiling point of molecules of similar size, depends on the differences in functional groups of the molecule.
For example CBr4 have a higher boiling point than other compounds because they have both London dispersion forces and dipole-dipole interactions.
2. Non-polar molecules like C5H12 will have low melting and boiling points, because they are held together by the weak van der Waals forces.
