Answer:
Mass = 38.3 g
Explanation:
Given data:
Mass of Cl₂ required = ?
Mass of phosphorus = 10.6 g
Solution:
Chemical equation:
P₄ + 6Cl₂ → 4PCl₃
Number of moles of P₄:
Number of moles = mass/ molar mass
Number of moles = 10.6 g/123.9 g/mol
Number of moles = 0.09 mol
Now we will compare the moles of P₄ with Cl₂ from balance chemical equation.
P₄ : Cl₂
1 : 6
0.09 : 6×0.09 = 0.54 mol
Mass of chlorine gas:
Mass = number of moles × molar mass
Mass = 0.54 mol × 70.9 g/mol
Mass = 38.3 g

Answer:
Modification Step
Explanation:
The entire reason why test-marketing exists is to make sure that the product will be well received by the public. Once the test marketing concludes, the data from the test is analyzed. Then the company decides whether or not they will make changes on how the product looks, feels, performs, or even rebranding the product, all to make sure that the final consumer will like the product enough to want to purchase and continuously use the product. Which will in term increase profits for the company.
