The molecule believed to have been the most important to the early protobionts is RNA.
RNA is believed to be the first functional macromolecule in protobionts because it is easier to synthesize than other macromolecules, has the ability to act as a catalyst, and can store genetic information. It is believed that RNA was the first molecule to form the basis for the earliest forms of life on Earth.
Protobionts are systems that are considered to have possibly been the precursors to prokaryotic cells. A protobiont is an aggregate of abiotically produced organic molecules surrounded by a non-unit membrane. This membrane provides a compartment for the molecules to interact and form more complex structures.

how many cl- ions are there in 400.5 grams of alcl3?
There are 1.806 x 1024 Cl- ions in 400.5 grams of AlCl3.
AlCl3 has an Avogadro number of 6.022 x 1023 molecules per 400.5 grams. AlCl3 molecules each contain three Cl- ions. Avogadro's number can therefore be multiplied by three to determine how many Cl- ions are present in 400.5 grams of AlCl3. We get about 1.806 x 1024 Cl- ions as a result. Since they are evenly distributed throughout the 400.5 grams of AlCl3, it is possible to determine their concentration by dividing the total number of ions by the volume of the solution.
A molecule is a smallest unit of a chemical substance that still retains its chemical properties. It is made up of two or more atoms that are chemically bonded together. The atoms in a molecule can be the same or different elements.

How can an oil spill occur?
Oil spills that happen in rivers, bays and the ocean most often are caused by accidents involving tankers, barges, pipelines, refineries, drilling rigs and storage facilities, but also occur from recreational boats and in marinas.
Spills can be caused by:
people making mistakes or being careless
equipment breaking down
natural disasters such as hurricanes, storm surge or high winds
deliberate acts by terrorists, acts of war, vandals or illegal dumping.
Most oils float on the oceans’ saltwater or freshwater from rivers and lakes. Oil usually spreads out rapidly across the water’s surface to form a thin oil slick. As the oil continues spreading, the slick becomes thinner and thinner, finally becoming a very thin sheen, which often looks like a rainbow. (In rare cases, very heavy oil can sometimes sink.)
Depending on the circumstances, oil spills can be very harmful to marine birds, sea turtles and mammals, and also can harm fish and shellfish. Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water-repelling abilities of a bird's feathers, exposing them to the harsh elements. Many birds and animals also swallow oil and are poisoned when they try to clean themselves or when eating oiled prey.
Fish and shellfish can also digest oil, which could cause changes in reproduction, growth rates or even death. Commercially important species such as oysters, shrimp, mahi-mahi, grouper, swordfish and tuna also could suffer population declines or become too contaminated to be safely caught and eaten.
Depending on just where and when a spill happens, from a few up to hundreds or thousands of birds, fish, mammals, reptiles, corals and other animals and plants can be killed or injured.
Vinegar is sold as a 5.00% solution of acetic acid. How many mL of water is in a 455mL bottle of vinegar?
430 mL of water is found in a 455 mL bottle of vinegar.
How to find the mL of water?The bottle of vinegar is labeled as 5.00% solution of acetic acid, meaning that 5% of the solution is acetic acid and the rest is water.
To find the amount of water in the bottle, we can subtract the portion that is acetic acid from the total volume.
This can be done by multiplying the volume of the bottle by the percentage of acetic acid, and then subtracting this result from the total volume:
Volume of water = Total volume - (Total volume * % acetic acid)
Volume of water = 455 mL - (455 mL * 5%) = 455 mL - (455 mL * 0.05) = 455 mL - 22.75 mL = 432.25 mL
So, there is approximately 432.25 mL of water in a 455 mL bottle of vinegar.

How the temperature changes with the height in the troposphere?
In reaction, the temperature in the troposphere falls with height.
In essence, the atmosphere is a shield of gases that protects all life on Earth by keeping temperatures within a narrow range and obstructing the sun's damaging rays. In essence, there is no distinction between the atmosphere and the outside world. The five separate layers of the atmosphere are created by the variations in temperature that occur with height. Following is a list of the five different layers:
Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere
The troposphere, which starts at the ground and rises to an altitude of roughly 10 kilometres above sea level, is the lowest layer of the atmosphere. It makes up 75% of the atmosphere's total air. The atmosphere distributes itself according to gravity, thus generally speaking, the temperature drops as you go up in height. With height, temperatures in the troposphere drop. This is due to the gas's low solar radiation absorption rate. Additionally, the ground takes in this radiation and heats the atmosphere through conduction and convection.
