The kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.

<h3>What is an amino acid?</h3>

An amino acid refers to a simple and organic chemical compound that consist of an acidic carboxyl group (COOH), a basic amino group (NH_2), and a unique side chain group.

<h3>What is a protein?</h3>

A protein can be defined as a <u>hydrophilic</u>, macromolecule (polymer) that is formed as a result of the union of many amino acids.

Generally, a protein contains the following chemical elements:

  • Oxygen (O) atoms
  • Hydrogen (H) atoms
  • Sulfur (S) atoms

In conclusion, the kind of molecule in this pizza is a protein because it is a polymer, <u>hydrophilic</u>, and it's made up of oxygen, hydrogen, and sulfur atoms.

Explain why the coin is able to float on top of the water in this glass.
zubka84 [21]
Surface tension is the result of water molecules pulling inward with a strong attractive force. 
The attractive force brings the molecules on the surface of the water close together.
The attractive force causes the surface of the water to be drawn toward the water molecules beneath the surface. <span>
Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.</span>

Which statement describes the formation of metamorphic rocks? Rocks beneath the surface melt. Rocks above the surface are eroded
butalik [34]

Answer:

<h3><em>i gotchu babes!</em></h3>

Explanation:

<h3><u><em>Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.</em></u></h3>

A piece of hot metal is put into an equal mass of water. The water temperature rises 5o and the metal’s temperature drops 10o. W
Mice21 [21]

Answer:

The answer to your question is     Cm = 2.093 J/kg°C

Explanation:

Data

mass metal = mass of water

Δ water = 5°

Δ metal = 10°

Cm = ?

Cw = 4.186 J/Kg°C

Formula

              for metal       for water

               mCmΔTm  = mCwΔTw

Cancel mass of metal

                  Cm ΔTm  =  CwΔTw

solve for Cm

                         Cm = (CwΔTw) / ΔTm

Substitution

                         Cm = (4.186 x 5) / 10

Simplification

                         Cm = 20.93 / 10

Result

                         Cm = 2.093 J/kg°C

Why does lithium have a higher ionization energy compared to sodium?
frez [133]

Answer:

There are 11 protons in a sodium atom but only 3 in a lithium atom, so the nuclear charge is much greater. ... The only factor left is the extra distance between the outer electron and the nucleus in sodium's case. That lowers the ionization energy.
