please answer the last question in this thread by the professor Re: Chapter 4 - DQ 2 posted by L.. Dec 08, 2017, 5:06 PM A limiting reagent is a chemical element or substance that limits the amount of product made during a chemical reaction. In order to find this, you would need a balanced equation", which would mean the number of atoms on the reactant side are equal to the number of atoms found on the product side of the equation I heard a very interesting way to explain this: You and a friend order pizzas and will split the cost. Each pizza costs $10; you have $10 and your friend only has $5. Now instead of each having a pizza, you and your friend must share the pizza. Another interesting way to look at this is car parts: we need 4 tires and 2 headlights to make 1 car. if l have a pile of 20 tires and 14 headlights, how many cars can be made? 20 tires will make 5 cars. 14 headlights will yield 7 cars, but I don't have enough tires for 7 cars. In this case, the tires are the limiting reagent. https://study.com, Limiting Reactant: Definition, Formulas, and Examples, https://chem.libretexts.org/Core/lnorganic_Chemistry/Chemical_Reactions/Limiting_Reagents Words: 174 e: Chapter 4 DQ 2 posted by C. _1. Dec 10, 2017, 12:23 PM It's a good analogy, Brittany! In other words if you have 1 million tires and 1 million headlights how many cars can you make how many of what is left over

Explanation / Answer

one car has 4 tyres but only 2 headlights

So,

headlight is limiting reagent

1 million tyres is used to make 0.25 million cars

0.25 million cars thus requires only 0.5 million head lights

So, 0.5 million head lights are still left over

Answer: 0.5 million head lights are left over
