The following data was collected when a reaction was performed experimentally in the laboratory.
Reptile [31]

The maximum amount of AlCl_3 produced during the experiment can be find out by knowing the Limiting Reagent.

Here, The maximum amount of AlCl_3 produced during the experiment is  400 grams

<h3>What is Limiting reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is stopped.

Now, According to the question,

Given ;

Number of moles of Al(NO_3)_3 - 4 moles

Number of moles of NaCl - 9 moles

To Find - Maximum amount of AlCl_3 produced during the reaction.

Solution ;

complete reaction ;

Al(NO_3)_3  + 3NaCl -->   3NaNO_3 + AlCl_3

To find the maximum amount of AlCl_3 produced during the reaction,

we need to find the limiting reagent.

Mole ratio Al(NO_3)_3  = 4/1 = 4

Mole ratio NaCl = 9/3 = 3

Thus, NaCl is the limiting reagent in the reaction.

Now, 3 moles of NaCl produces 1 mole of   Al(NO_3)_3

9 moles of NaCl will produce = 1/3 x 9 = 3 moles.

Weight of   Al(NO_3)_3 = 3 x 133.34 = 400 grams

Thus, 400 grams of   Al(NO_3)_3  is the maximum amount of   Al(NO_3)_3 produced during the experiment.

What steps have power plants taken to reduce the amount of sulfur oxides released into the air?
Ann [662]
Emissions of SO2 generated during the combustion of fossil fuels can be reduced<span> by treating the flue gases before they are emitted into the atmosphere via the stack; this is termed Flue Gas Desulphurisation (FGD). Flue gas desulphurisation systems can be classified as either Regenerable or Non-regenerable.

I hope my answer has come to your help. God bless and have a nice day ahead!

list the four quantum numbers from LAST electron of each of the following elements in their ground state: sodium, nitrogen, oxyg
Rasek [7]

Explanation:

The four quantum  numbers gives the position of the orbital, its spatial orientation, the shape of the orbital and the spin of the an electron in the orbital.

The principal quantum number(n) gives the main energy level in which the orbital is located; n = 1,2,3,4....

Azimuthal or secondary quantum number (l) gives the shape of the orbitals an they take values l = 0,1,2,3.... and their names are s for 0, p for 1, d for 2 and f for 3.

Magnetic quantum number gives the spatial orientation or degeneracy of the orbitals in the subshell.

Spin quantum number gives the spinning of the electrons

Electronic configuration:

Na = 1s² 2s² 2p⁶ 3s¹

   The last electron enters the 3s¹

           n = 3

            l = 0

           m = 0

            spin =+ or - \frac{1}{2}

N = 1s² 2s²  2p³

           last electron enters 2p³

              n = 2

              l = 1

               m = -1, 0, 1

               spin = + or - \frac{1}{2}

O = 1s² 2s² 2p²

    last electron enters  2p²

             n = 2

              l = 1

               m = -1, 0, 1

               spin = + or - \frac{1}{2}

Cl =1s² 2s² 2p⁶ 3s² 3p⁵

     last electron enters 3p⁵

               n = 3

              l = 1

               m = -1, 0, 1

               spin = + or - \frac{1}{2}

S = 1s² 2s² 2p⁶ 3s² 3p⁴

      last electron enters 3p⁴

               n = 3

              l = 1

               m = -1, 0, 1

               spin = + or - \frac{1}{2}

What is [OH-]? Please include work so I know how to answer future questions. Thanks! :)
kramer

Answer:

i know it is alot but that is how are teacher told us to do, hope this is correct

Explanation:

a. 2.6

b. 12.0

Explanation:

a.

First, we will calculate the molar concentration of HCl.

M = mass of HCl / molar mass of HCl × liters of solution

M = 0.40 g / 36.46 g/mol × 4.5 L

M = 2.4 × 10⁻³ M

HCl is a strong monoprotic acid, so [H⁺] = 2.4 × 10⁻³ M. The pH is:

pH = -log [H⁺]

pH = -log 2.4 × 10⁻³ = 2.6

b.

First, we will calculate the molar concentration of NaOH.

M = mass of NaOH / molar mass of NaOH × liters of solution

M = 0.80 g / 40.00 g/mol × 2.0 L

M = 0.010 M

NaOH is a strong base with 1 OH⁻, so [OH⁻] = 0.010 M. The pOH is:

pOH = -log [OH⁻]

pOH = -log 0.010 = 2.0

The pH is:

14.00 = pH + pOH

pH = 14.00 - pOH = 14.00 - 2.0 = 12.0
