why is the layer of fat on top
Answers
Answer:
The solid layer of fat on top protects the broth from freezer burn. When I take the broth out of the freezer I use a butter knife to pop the fat cap off before defrosting. I do save chicken fat from soup and use it instead of butter or olive oil when I cook onions.

Answers
As the sun sets, the temperature of the room decreases. Explain how this affects the particle motion of the gas particles in the room. Be sure to include collisions, kinetic energy, pressure, and thermal energy in your answer.
Answers
Answer:
Heres a very LONG answer-
The real answer:
Its in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

Which of the following best describes the velocity of an object?
A B0 m/s
B 30 m east
C 30 m/s east
D 30 m/s2
Answers
30 m/s east
Answer:
[tex]\boxed {\boxed {\sf C. \ 30 \ m/s \ east}}[/tex]
Explanation:
Velocity is the vector measurement of the change in position over time. A vector measurement means the answer must include a magnitude (numerical value) and a direction.
Here are some units of velocity:
m/s (meters per second) kph (kilometers per hour) km/s (kilometers per second)There are many other units, but m/s is the most common.
We can eliminate choice B and D, because the units (meters-m and meters per second squared-m/s²) are not for velocity.
We are left with choice A (30 m/s) and C (30 m/s east). Remember, velocity needs a number and a direction. C contains the direction east, so it must be the correct answer.

Which periodic table trend is represented by the blue arrows?
Answers
Answer:
Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.

What is the molecular formula of the compound with a molecular weight of 112 g/mol and percent composition: 85.6% C and 14.4% H?
Select one:
a. C2H4
b. CH2
c. C4H8
d. C8H16
Answers
Answer:
Molecular formula = C₈H₁₆
Explanation:
Given data:
Percentage of hydrogen = 14.4%
Percentage of carbon = 85.6%
Molecular formula = ?
Molecular weight = 112 g/mol
Solution:
Number of gram atoms of H = 14.4/ 1.01 = 14.26
Number of gram atoms of C = 85.6/ 12 = 7.13
Atomic ratio:
C : H
7.13/7.13 : 14.26/7.13
1 : 2
C : H = 1 : 2
Empirical formula is CH₂
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
n = 112 / 14
n = 8
Molecular formula = n (empirical formula)
Molecular formula = 8 (CH₂)
Molecular formula = C₈H₁₆
