What is the theoretical yield of waffles if you have 6 cups of flour, 9 eggs and 2 tbs of oil?
Yanka [14]

Answer:

8 waffles

Explanation:

First, find the limiting reagent.  Divide the amount you have by the amount that is needed.  The smallest number is the limiting reagent.  <u>For this problem, the limiting reagent is oil.</u>

6 cups of flour/2 cups of flour = 3

9 eggs/3 eggs = 3             2 tbsp of oil/1 tbsp of oil = 2

This means that we can double the recipe since we have enough of each ingredient to make two batches.  Multiply the entire equation by 2.  This should give you   4 cups of flour  +  6 eggs  +  2 tbsp of oil  ==>  8 waffles.

<u>You should theoretically get 8 waffles.</u>

A gas is contained in a thick-walled balloon. When the pressure changes from 39.1 bar to 87.0 bar the volume changes from blank
lidiya [134]

Answer: -

1.34 L

Explanation: -

Initial Pressure P 1 = 39.1 bar

Initial Temperature T 1 = 643 K

Let the initial volume be V 1.

Final pressure P 2 = 87.0 bar

Final temperature T 2 = 525 K.

Final volume V 2 = 0.492 L

Using the equation

\frac{P1 V 1}{T1} = \frac{P 2 V 2}{T2}

V 1 = \frac{P2 V2 T1}{P 1 T2}

Plugging in the values

We have

V 1 = 87 bar x 0.492 L x 643 K / (39.1 bar x 525 K)

= 1.34 L

Thus, a gas is contained in a thick-walled balloon. When the pressure changes from 39.1 bar to 87.0 bar the volume changes from 1.34 L to 0.492L and the temperature changes from 643K to 525K
