You are a researcher for a golf club manufacturer. You are given two identical looking cubes of a metal alloy. You are informed

that they are made of the exact same material, but one is a crystalline, while the other is amorphous. It is your job to determine which one is amorphous because this one is more stress-resistant and is useful in reinforcing golf clubs. Which of the following is the best way to determine which is which?
A. Determine the density of each cube. The more dense one is the amorphous solid.

B. Determine the density of each cube. The less dense cube is the amorphous solid.

C. Melt both cubes and look for a broader range of melting temperatures. The one that melts over a broader range of temperatures is the amorphous solid.

D. Melt both cubes and measure the range of melting temperatures. The one that melts over a narrower range of temperatures is the amorphous solid.

Answer:

C.Melt both cubes and look for a broader range of melting temperatures. The one that melts over a broader range of temperatures is the amorphous solid.

Explanation:

Amorphous solids is one that do not have a fixed melting points but melt over a wide range of temperature due to the irregular shape hence its name. Contrariwise crystalline solids, have a fixed and sharp melting point.

This comes in handy to solve the riddle. We can characterise the pair with the melting point property.

A crystallographer measures the horizontal spacing between molecules in a crystal. The spacing is 10.59 nm . What is the total w
Readme [11.4K]
Whenever objects are placed in a line with spaced in between them, the number of spaces is one less than the number of objects. For reference, you may hold up four fingers and count the spaced between your fingers.

Therefore, if there are 105 molecules, then there are 104 spaces present.

We also know that 1 mm = 1000 nm. So, we first convert the spacing to millimeters as the final answer is required in millimeters

spacing = 10.59/1000 = 0.01059 mm

Now, the width of the lattice will be (ignoring the size of the molecules):

104 * 0.01059

1.10 millimeters

Secondary bile salts lack a hydroxyl (OH) group when compared to primary bile salts. What is the consequence of the loss of this
Slav-nsk [51]

Answer:

When secondary bile salts (or acids) lack a OH, they are reabsorbed

Explanation:

The lost of a hydroxyl group (OH) in the bile salts structure means less hydro solubility. Thus, they are not eliminated, conversely, the are reabsorbed for intestine and they go back to the liver.
