Answer:

Noble Gases B

Explanation:

Substances that make up a mixture __________ their own properties once they are combined to form a mixture. Please help. I need
Stels [109]
I believe the answer to this is;
Substances that make up a mixture RETAIN their own properties once  they are combined to form a mixture. 
    I believe the answer is RETAIN because the combination in question is a MIXTURE. A mixture is a combination of various substances. In the case of mixtures, all the substances retain their own properties. That is; they remain the way they are and do not change. An example of a mixture is air. And to prove that air is a mixture;
The components of air retain their individual properties.
The components of air cannot be represented by a chemical formula
When the components of air combine, they do not show any form of chemical change, like heat release, change in pressure.....
  Hope i helped, have a nice day.

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>
