Tyrone and Valerie wanted to determine what feature of a paper airplane would cause it to fly the farthest. Tyrone made his airp

lane with wider wings than Valerie’s airplane. Valerie’s airplane had shorter wings, and the plane was also narrower and longer than Tyrone’s. After testing the two airplanes several times, the evidence shows that Tyrone’s airplane flew farther through the air than Valerie’s airplane.
Describe why the investigation above is not adequate to explain which airplane feature caused Tyrone’s airplane to fly farther than Valerie’s.

Using what Tyrone and Valerie have already observed, suggest a possible hypothesis regarding one feature of a paper airplane.

Identify the independent and dependent variables. Describe, in detail, a procedure to test your hypothesis. Identify the controlled variables.

Answer:

19.4 g of alum, will be its theoretical yield

Explanation:

The reaction is:

2 Al + 2 KOH + 4 H₂SO₄ + 22H₂O → 3H₂ + 2KAl(SO₄)₂•12H₂O

Let's determine the amount of acid.

M are the moles contained in 1 L of solution or it can be mmoles that are contained in 1 mL of solution

M = mmol /mL

M . mL = mmol

We replace: 8.3 mL . 9.9 M = 82.17 mmoles

We convert to moles: 82.17 mmol . 1 mol / 1000mmol = 0.082 moles

Ratio is 4:2

4 moles of sulfuric acid can make 2 moles of alum

By the way, 0.082 moles of acid may produce ( 0.082 . 2) /4 = 0.041085 moles.

We convert moles to mass:

Molar mass of alum is: 473.52 g/mol.

0.041085 moles . 473.52 g/mol = 19.4 g

Why do animals need carbohydrates in their diets
Sever21 [200]

Answer:

Carbohydrates are energy-providing feed components composed of carbon, hydrogen, and oxygen. They should make up about 75 percent of an animal's diet. The energy they provide powers muscular movements. Carbohydrates also produce the body heat that helps keep the animal warm.
