What's a good idea for a limiting reactant project
amid [387]
Original Recipe
1 (18 1/4 ounce) Box devils food cake mix
1/2 cup vegetable oil
2 large eggs
Confectioners' Sugar (for rolling)

Directions:
Preheat oven to 350 degrees. Stir (by hand) cake mix, oil, and eggs- until dough forms. Dust with sugar and shape into 1 inch balls. Roll balls in sugar and place on ungreased cookie sheet. Bake 8-10 minutes. Remove from pan after one minute and put on cooling rack.
Cooking for 17 people
My original yield was 30 cookies.

17 cookies (1box cake mix/30 cookies)= .56 of a box= 1/2 box

17 cookies (1/2 cup oil/30 cookies)= .283 cups of oil= 1/4 cups

17 cookies (2 eggs/30 cookies)= 1.13 eggs= 1 egg
Percent Yeild
I was able to bake 24 cookies, with my original yeild being 30.


(24 cookies/30 cookies) x 100= 80% yeild

Will larger crystals will be formed when molten rock cools more slowly
STatiana [176]
Yes, the crystals will have more time to form and therefore are more likely to be larger compared to one that is cooled quickly.

Why aren't descriptive investigations repeatable?
Sergeu [11.5K]
I would say that descriptive investigations aren't repeatable because it means that you are only describing something - you ask certain question about something, but do not form a hypothesis at that point yet. So it would be a waste of time to simply ask the same questions over and over again with no hypothesis to prove, which is why these types of investigations cannot be repeated.

During an investigation a scientist burned 48 g of magnesium strip. After the reaction the total mass of the product formed was
ddd [48]

Answer:

The law of conservation of mass applies to both cases

      When 50 g of sugar undergoes a physical change, say for example  melting, the amount of sugar in the solution or melted form will also be 50 grams. This shows that the mass before and after the change was the same, in accordance to the law of conservation of mass. The mass stays the same.

When the magnesium strip is burned, this is a chemical reaction. The problem is that we only measure the mass of one of the substances involved in the reaction which is the magnesium strip, which makes it seem like the mass has increased. Actually, while burning, the magnesium combines with oxygen in the air. This oxygen was present before the reaction, we just did not measure it. And after the reaction it is present in the form of product. But the mass is still conserved.

Hope this helps!!:)
