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

Answer:
D
Explanation:
Earth's greenhouse gases trap heat in the atmosphere and warm the planet.
If the number of moles decreases from 5 moles of gaseous reactants to 2 moles of gaseous product, the overall change in volume of the system is negative.
<h3>What is volume?</h3>
Volume refers to the space occupied by an object. Gases do not have a specific volume, rather they take on the volume of the container. We must note that the volume of given mass of gas is directly proportional to the number of moles present.
Hence, if the number of moles decreases from 5 moles of gaseous reactants to 2 moles of gaseous product, the overall change in volume of the system is negative.
