This impurity is troubling from an economic standpoint because it lead to decrease in the yield of phosphorus

  • Ferrophosphorus is a byproduct of phosphorus production in submerged-arc furnaces , by their reduction with carbon. It is formed from the iron oxide impurities.
  • Iron impurities present in the calcium phosphate will be precipitated out as the iron phosphate which eventually will lead to the decrease in the yield of phosphorous during the production of phosphorous.

Thus we can conclude that Fe₂P causes decrease in yield

he mass defect of the helium nucleus ⁴He₂ is 0.030377 u

Further explanation

Mass defect means the difference between the mass of particles forming an atom with an atomic mass.

Δm = mass defect ( u )

mp = mass of proton ( u )

me = mass of electron ( u )

mn = mass of neutron ( u )

M = atomic mass ( u )

A = mass number

Z = atomic number

Identify the single displacement reaction. C4H12 + 7O2 ⟶ 6H2O + 4CO2 2H2 + O2 ⟶ 2H2O Al2S3 ⟶ 2Al + 3S Cl2 + 2KBr ⟶ 2KCl + Br2
Varvara68 [4.7K]

Answer:- Cl_2+2KBr\rightarrow 2KCl+Br_2

Explanations:-  The first reaction is combustion reaction as the hydrocarbon is burned in presence of oxygen to give carbon dioxide and water.

Second reaction is the synthesis reaction as in general a synthesis reaction looks like:

A+B\rightarrow AB

Third reaction is the decomposition reaction as it looks opposite of synthesis reaction.

AB\rightarrow A+B

In general, a single displacement reaction looks like:

AB+C\rightarrow AC+B

Fourth reaction is single replacement reaction as bromine is replaced by chlorine.

So, the correct choice is the last reaction, Cl_2+2KBr\rightarrow 2KCl+Br_2 .

What is the concentration of a solution containing 0.32 moles of NaCl in 3.4 liters?
dsp73
Get the molarity we need to divide the number of moles of NaCl by the volume of the solution. So, 0.32 moles NaCl divided by 3.4 L, and that gives 0.094 M NaCl.
