why is the layer of fat on top
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.

calculate the molar mass of cacl2
Answer:
[tex]\boxed {\boxed {\sf 110.98 \ g/mol}}[/tex]
Explanation:
The molar mass is the mass of a substance in grams per mole.
To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.
The compound given is:
[tex]CaCl_2[/tex]
The compound has 1 Ca (calcium) and 2 Cl (chlorine).
Mass of Calcium
The molar mass of calcium is 40.08 g/mol There is only one atom of Calcium in CaCl₂, so the number above is what we will use.Mass of Chlorine
The molar mass of chlorine is 35.45 g/mol There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2. 35.45 * 2= 70.9 g/molMolar Mass of CaCl₂
Now, to find the molar mass, add the molar mass of 1 calcium and 2 chlorine. 40.08 g/mol + 70.9 g/mol =110.98 g/molThe molar mass of CaCl₂ is 110.98 grams per mole.
What are some examples of HIGH resistance? Question 2 options:
long wire, wide wire, more resistors
wide wire, short wire, less resistors
long wire, narrow wire, more resistors
narrow wire, less resistors, long wire
(PLEASE HURRY! I NEED TO FINISH THIS QUIZ)
Answer:
long wire, wide wire, more resistors
long wire, narrow wire, more resistors
Explanation:
longer wires have greater resistance. The longer the wire the greater the resistance.
The answer is Long wire, Narrow wire, more resistors

Which elements are abundant in visible universe
Hydrogen is the most abundant element in the Universe; helium is second. However, after this, the rank of abundance does not continue to correspond to the atomic number; oxygen has abundance rank 3, but atomic number 8. All others are substantially less common.

Explanation:
An object is moving across a surface, but it does not gain or lose speed. Which best describes the object’s force?
Answer:
Explanation:
the vector sum of all such forces which equals zero for an object at rest. CASE 1: Considering a basketball of weight 1kg, if it has been kept stationary on the ground, there are two forces acting on it. These are it's weight (gravity) and equal and opposite force from the ground (normal reaction).
Answer:
The net force is zero. :)
Explanation:
A scientist thinks he found a new metal, so he published a paper about this metal. About 1 week after the scientist published the paper, you noticed a problem with the paper the scientist wrote. You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered. Using the techniques from Chemistry, you ran a Flame Test with a piece of the metal (the metal is safe to use) that you had shipped to you. You found the metal turned the flame yellow. What metal did you have in your possession?
**ANSWER CHOICES**
*Barium
*Calcium
*Strontium
*Copper
*Sodium
Answer:
Sodium

Explanation:
It relates with Barium which burns with yellowish green flame

Explanation:
New colors produced when any two of the primary colors of pigment are mixed; red, green, and blue
Answer:
A simulated example of additive color mixing. Additive primaries act as sources of light. The primaries red, green, and blue combine pairwise to produce the additive secondaries cyan, magenta, and yellow. Combining all three primaries (center) produces white.
when all of the primary colors are mixed it makes black

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.
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.

Explanation:
Which periodic table trend is represented by the blue arrows?
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.
