Your Answer Is A. Foliated

Pavlova-9 [17]4 years ago
4 0

Foliated metamorphic rocks such as gneiss, Phyllis, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance.

show transcribed data consider two organic molecules, ethanol and benzene. one dissolves in water and the other does not. why? t
aalyn [17]

Benzene lacks a polar O-H bond, but ethanol does. Benzene C6H6 with ethanol C2H6O.

Benzene fails the iodoform test, whereas ethanol does.

While ethanol burns with a non-luminous flame, benzene produces a sooty flame.

Iodoform testing shows that ethanol passes whereas benzene does not.

In contrast to benzene, which generates a sooty flame, ethanol burns with a non-luminous flame.

Water does not mix with benzene, but organic solvents do.

It is a colorless liquid with a pleasant scent.

Benzene has a high melting point and a moderate boiling point.

It burns with a sooty flame and is quite flammable.

A clear, colorless liquid, ethanol has a distinct flavor of burning with a nice aroma. It has high flammability. Ethanol combines easily with water and a variety of organic liquids and is used to dissolve other chemical compounds.

Tris has a molecular weight of 121 g/mol. How many grams of Tris would you need to make 100 mL of a 100 mM solution of Tris
Zepler [3.9K]

Answer:

1.21 g of Tris

Explanation:

Our solution if made of a solute named Tris

Molecular weight of Tris is 121 g/mol

[Tris] = 100 mM

This is the concentration of solution:

(100 mmoles of Tris in 1 mL of solution) . 1000

Notice that mM = M . 1000  We convert from mM to M

100 mM . 1 M / 1000 mM = 0.1 M

M = molarity (moles of solute in 1 L of solution, or mmoles of solute in 1 mL of solution). Let's determine the mmoles of Tris

0.1 M = mmoles of Tris / 100 mL

mmoles of Tris = 100 mL . 0.1 M → 10 mmoles

We convert mmoles to moles → 10 mmol . 1mol / 1000mmoles = 0.010 mol

And now we determine the mass of solute, by molecular weight

0.010 mol . 121 g /mol = 1.21 g
