When 5.0 mol Al react with 13 mol HCl, what is the limiting reactant, and how many moles of AlCl3 can be formed? (2 points) 2Al

+ 6HCl → 2AlCl 3 + 3 H 2
Al is the limiting reactant; 5.0 mol AlCl3 can be formed

HCl is the limiting reactant; 4.3 mol AlCl3 can be formed

Al is the limiting reactant; 7.5 mol AlCl3 can be formed

HCl is the limiting reactant; 6.5 mol AlCl3 can be formed

Well, we need to find the ratio of Al to the other reactant.

Al:HCl = 1:3

--> this means that for every 1 Al used, you have to use 3 HCl.


5*3 = 15 moles of HCl needed to fully react with 5 moles of Al. Since 13<15, HCL is the limiting reactant.


The ratio of HCl:AlCl = 3:1


13/3 = 4.3333...


The final answer is HCl is the limiting reactant with 4.3 moles of AlCl3 able to be produced so choice B.


Hope this helps!!! :)

Consider the reaction between reactants s and o2: 2s(s)+3o2(g)→2so3(g)if a reaction vessel initially contains 7 mols and 9 mol o
nadya68 [22]

Answer: -

1 mol

Explanation: -

Number of moles of Sulphur S = 7

Number of moles of O2 = 9

The balanced chemical equation for the reaction is

2S (s)+3 O2 (g)→2SO3(g)

From the above reaction we can see that

3 mol of O2 react with 2 mol of S

9 mol of O2 will react with \frac{2 mol S x 9 mol O2}{3 mol O2}

= 6 mol of S

Unreacted S = 7 - = 1 mol.

If a reaction vessel initially contains 7 mol S and 9 mol O2

1 mole of s will be in the reaction vessel once the reactants have reacted as much as possible

What is the atomic mass of an oxygen isotope that has 8 protons and 10 neutrons in its nucleus? 8 amu 10 amu 18 amu not enough i
Irina-Kira [14]

The atomic mass can be defined as the mass of neutrons and protons in the atom. The atomic mass of the oxygen isotope is 18 amu.

<h3>What is an atom?</h3>

An atom is the smallest particle comprised of three subatomic units, namely electrons, protons, and neutrons.

The number of electrons in the atoms determines the atomic number, while the number of protons and neutrons determines the atomic mass.

The atomic mass can be given as:

\rm Atomic\;mass=Neutrons+Protons

The oxygen isotope has been comprised of 10 neutrons and 8 protons. The atomic mass of the isotope is given as:

\rm Atomic \;mass=10+8\;amu\\Atomic\;mass=18\;amu

The atomic mass of the oxygen isotope is 18 amu. Thus, option C is correct.
