Calculate the number of moles in 144 g of P. Please show your work to receive credit.
NeX [460]

Answer:

144 g of phosphorus contain 4.65 moles.

Explanation:

Given data:

Mass of phosphorus (P) = 144 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of phosphorus is 31 g/mol

Now we will put the values in formula.

Number of moles = 144 g/ 31 g/mol

Number of moles = 4.65 mol

Thus, 144 g of phosphorus contain 4.65 moles.

Which reaction will occur? 2NaBr I2 Right arrow. 2NaI Br2 2Fe Al2O3 Right arrow. 2Al Fe2O3 2AgNO3 Ni Right arrow. Ni(NO3)2 2Ag P
Likurg_2 [28]

The reaction that has been occurred will be \rm 2\;Fe\;+\;Al_2O_3\;\rightarrow\;2\;Al\;+\;Fe_2O_3.

The chemical reaction has been defined as the interaction of the reactant  molecules for the formation of the product. The changes have been taken place in the reactivity series and under specific conditions.

<h3>Reaction occur</h3>

The displacement reaction has been taken place based on the reactivity series. The more reactive element has been able to displace the less reactive element in the compound and form a new compound.

The following reactions have been analyzed as:

  • \rm 2\;NaBr\;+\;I_2\;\rightarrow\;2\;NaI\;+\;Br_2

In the reaction, Br has been replaced by Iodine. The iodine has been less reactive than Br and thus will not form the compound.

Thus, this reaction will not occur.

  • \rm 2\;Fe\;+\;Al_2O_3\;\rightarrow\;2\;Al\;+\;Fe_2O_3

In the reaction, Al has been replaced by Fe. The Fe is more reactive than Al. thus this reaction will occur.

  • \rm 2\;AgNO_3\;+\;Ni\;\rightarrow\;Ni(NO_3)_2\;+\;2\;Ag

The nickel has been less reactive than Ag, and thus will not be able to form the product.

Thus, this reaction will not occur.

  • \rm Pb\;+\;Zn(C_2H_3O_2)_2\;\rightarrow\;Zn\;+\;Pb(C_2H_3O_2)_2

The lead has been less reactive than Zn, and thus will not be able to form the product.

Thus, this reaction will not occur.

The reaction that has been occurred will be \rm 2\;Fe\;+\;Al_2O_3\;\rightarrow\;2\;Al\;+\;Fe_2O_3.

Why is it necessary to add concentrated HCl, then water, rather than a solution of HCl to the eudiometer tube
Dmitry_Shevchenko [17]
The reaction between concentrated acid and water can release a lot of heat. If a little water is added to a larger amount of acid, the heat can cause the small amount of water to boil very rapidly which then spatters some acid. ... It is recommended that acid should be added to water and not water to acid.
