Which macromolecule is not a polymer?

The closest lipids to polymers are triglycerides. These lipids are formed by multiple fatty acid chains connected to a glycerol backbone. However, lipids can have non-repeating ring structures or consist of a single fatty acid chain. Lipid structure consists of long chains or ring structures with only carbon and hydrogen atoms. As a result, lipids are "hydrophobic" and do not interact with water.

How do you calculate the Ka of HC2H3O2?

The concentrations used in the equation for Ka are known as the equilibrium concentrations and can be determined by using an ICE table that lists the initial concentration, the change in concentration and the equilibrium concentration for H3O+, C2H3O2 and HC2H3O2. The concentration is listed in moles per liter.\nIn the table, the change in concentration for HC2H3O2 is -x, while the concentration of each of the products is x. Then, the equilibrium concentration for HC2H3O2 is the initial molarity of HC2H3O2 minus x, while the concentration of the products is any initial molarity plus x. For exa..

What happens to the density of water as the temperature decreases?

Density is an important physical characteristic of substances that measures how much matter is contained within a specific amount of volume. Density can be measured and compared for liquids, solids and gases. If a substance has a lower density than another it will tend to rise or float above the other.

What does two liters equal?

When converting recipes from metric measurements to U.S. customary measurements, 1 liter converts to 4 cups for both dry and liquid ingredients. Cooks double this amount to convert 2 liters. Liter is the standard measurement for volume in the metric system. One-thousandth of a liter is equal to a milliliter. Milliliters are used to measure small quantities. One-thousand liters is equal to a kiloliter. Kiloliters are used to measure large quantities.

What is manganese VII oxide?

One molecule of manganese(VII) oxide contains two atoms of manganese and seven atoms of oxygen. It has molar mass of about 221.87 grams per mole and a density of 2.79 grams per cubic centimeter. It can be produced through a reaction of potassium permanganate and sulfuric acid. The compound is explosive when heated past 55 degrees Celsius. It has a melting point of 6 degrees Celsius. Manganese(VII) oxide ionizes when it reacts with sulfuric acid.

What is the difference between relative and absolute age?

Relative age comes up often in various fields, such as archeology. If archaeologists find a site with layers in it, they can make assumptions about the relative age based on the composition of materials in each layer. For example, if an area used for trash has modern refuse in it such as CDs and computers, and the layer underneath has cans made of tin, then it is safe to say the layer of tin cans have a greater relative age than the layer with modern refuse. However, this does not say anything about the absolute age of the layers. That is, scientists cannot tell exactly how old the layers are ..

Is K2SO4 soluble in water?

Ammonia has a very strong salting out effect when mixed with K2SO4 that is stronger than water. K2SO4 is also known as arcanite, sulfate of potash and potash of sulfur and is also non-flammable and principally used in fertilizers. It can also be used in glass manufacturing, as a flash reducer in artillery propellant charges. Arcanite is potassium sulfate's mineral form and is relatively rare.

In what way are plants and animals similar?

On a cellular level, plants and animals are very similar. Both have cells that are large, compared to prokaryotic cells, and internally complex. All eukaryotic cells have simple plasma membranes, unlike the complex cell walls of prokaryotes. They also have complex internal arrangements of intracellular organelles that are specialized to perform various functions in the body's chemistry. Most plant and animal cells have a nucleus, which houses the organism's genetic material.\nThis genetic material is organized in a similar way for both groups. In each, DNA is arranged in a linear fas..

Are there any types of structures that are not sedimentary?

Igneous rocks, which are grouped into intrusive and extrusive, solidify from a partially or fully molten state. Extrusive rocks normally have a fine-grained texture due to rapid cooling of magma when subjected to the surroundings. Some examples are andesite, basalt and rhyolite. Magma that solidifies underground form intrusive rocks. Some examples are diorite and granite.Metamorphic rocks refer to ones that were changed due to pressure, heat or chemical reaction of gases or fluids. The structures are classified as either nonfoliated or foliated. The nonfoliated type has a planar structure, whi..

What is the function of the nasal cavity?

Of the four sinuses, the frontal sinuses are located just above each eye, the maxillary sinuses are behind each cheekbone, the sphenoid sinuses are located near the optic nerves and the ethmoid sinuses are a collection of voids that open up into the other sinus cavities.\nThe sinuses serve as a partially closed system for heat and moisture. When air passes in through the nose, the humidity and warmth of the sinus cavity warms the air to within 1 degree of body temperature and moisturizes it to prevent a shock to the lungs. The air passes down into the lungs where it provides oxygen to the body..
