The ingredients that is important in making plastics is natural gas plant liquids.
Natural gas liquids (NGLs) are components of natural gas which are separated from the gas state in the form of liquids. They many applications including; plastic production, inputs for petrochemical plants, they are also burned for space heat and cooking, and can also be blended into vehicle fuel.
In the manufacturing of plastics, come components of NGLs are used. And for this case, ethane. Ethane is used in the production of ethylene which are passed through pressure and catalyst to be turned to plastics like polythene.
The reason why they are mostly used in the manufacturing plastics than other resources like crude oil is that it is much cleaner.

In an experiment, a solution required 30. 05 g of nacl, 50. 0 g of , and 0. 4006 g of mgso4. Using the correct number of significant figures, what is the resulting mass?.
When the use of significant figures and rounding up is applied correctly the mass of the mixture will be 80.5 g.
In cases of addition or subtraction, only the last significant figure of every number is taken into account.
In 30.05, this is 5, in the hundredths. When we look at 50.0, the last significant figure is 0, and it is in the tenths. And in 0.4006, the last significant figure is 6, in the ten thousandths. Of these three, the 0 from 50.0 is in the leftmost position, which means that the last significant figure of the result needs to be in the same position (in the tenths).
Moving onto the actual algebraic operation:
30.05 g + 50.0 g + 0.4006 = 80.4506 g
As we established, the last significant figure should be in the tenths, and we will have to round up 4 to 5 (trailing numbers are greater than 0), which means that the resulting mass will be 80.5 g.

What is atoms?An atom is a matter particle that defines a chemical element uniquely. An atom is made up of a central nucleus and one or more negatively charged electrons.The nucleus is positively charged and contains one or more heavy particles called protons and neutrons. An atom exists as an essential particle of value that contains at least one proton.Here are a few atom examples: neon (N) and hydrogen (H) (Ne). Because atoms were once thought to be the smallest things in the universe and could not be divided, the term "atom" comes from the Greek word for indivisible.

The motion of one particle of a gas is unaffected by the motion of other particles of the gas unless the particles _____.
d is movement of molecules from high concentration to low concentration. an example is lemon essential oil used in one corner of the room but soon smelled in the opposite corner.
A substance diffuses when it moves from a region of high concentration to one of low concentration. Because the particles in liquids and gases travel randomly from one location to another, diffusion occurs in these media. For living things, diffusion is a crucial process because it governs the flow of materials into and out of cells.
A net migration of anything from a zone of higher concentration to a location of lower concentration can also be described as it, and a gradient in concentration is what's driving it.
Without spending the cell's energy, substance that crosses a cell membrane travels away from the region where it is concentrated.
Passive transport is the term for it.
It is the process by which substances migrate down the gradient of concentration without utilizing cellular energy.
Simple diffusion is another name for it.
Due to the difference in concentration from the perfume bottle to the outside environment, when a perfume bottle is opened, particles disseminate in the air.
While, active transport substances should move in the opposite direction of the concentration gradient, or toward the area of higher concentration.
Energy is needed for this procedure.

the molar heat capacity of silver is 25.35 j/mol⋅∘c . how much energy would it take to raise the temperature of 8.20 g of silver by 17.3 ∘c ? express your answer with the appropriate units.
33.34 J of energy it would take to raise the temperature.
Specific heat = J/g C
(25.35 J/mole C) x (1 mole / 107.8682g) = 0.2350 J/g C
Energy required = (mass in grams)x(Specific heat)x(Temp final - Temp initial)
= (8.20 g)(0.2350 J/g C)(17.3°C) = 33.34 J (units cancel for /g C)
Heat capacity or specific heat is the quantity of heat consistent with unit mass that is required to elevate the temperature with the aid of 1°C. particular warmness is helpful in figuring out the processing temperatures and quantity of warmth vital for processing and may be helpful in differentiating between polymeric composites.
The specific heat capacity (or in reality, the specific heat), that's the heat potential according to unit mass of a material. Experiments show that the transferred heat relies upon on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance.

4.2 g of lithium (Li) reacts with 2.8 g of nitrogen (N2). Find the simplest molar ratio in which lithium reacts with nitrogen.
The simplest molar ratio in which lithium reacts with nitrogen is 6 moles of lithium to 1 mol of nitrogen.
What is molar ratio?
A molar ratio examines the ratio that exist between two chemical compounds showing the amounts in moles of the compounds involved in a chemical reaction.
Molar ratio = amount of a constituent in moles ÷ total amount of all constituents in a mixture in moles
Given:
Mass of lithium (Li) = 4.2 g
Mass of nitrogen (N2) = 2.8 g
Total amount of mass = 7g
Moles = molecular weight ÷ mass of water
Moles of lithium (Li) = 4.2 ÷ 7 = 0.60 mol
Moles of nitrogen (N₂) = 2.8 ÷ 7 = 0.10 mol
Therefore, ratio Li : N₂ = 0.60 : 0.10 = 6 : 1
6 Li + N₂
The balanced equation between lithium and nitrogen, to form lithium nitride = 6 Li + N₂ → 2 Li₃N₆L i + N₂ → 2Li₃N
In summary, the simplest molar ratio in which lithium reacts with nitrogen is 6:1

How would you calculate the number of barium atoms present in two moles of barium?
A) Multiply the atoms of barium by Avogadro's number.
B) Multiply the moles of barium by Avogadro's number.
C) Divide the moles of barium by Avogadro's number.
D) Add Avogadro's number to the number of atoms.
To calculate the number of barium atoms present in two moles of barium, we need to multiply the moles of barium by Avogadro's number (B)
A mole of a compound contains 6.022 x [tex]10^{23}[/tex] atoms.
6.022 x [tex]10^{23}[/tex] atoms is the Avogadro’s number which denotes the molecular weight in grams.
Thus, one mole of barium would have 6.022 x [tex]10^{23}[/tex] barium atoms
Therefore, two moles of barium would be multiplication of number of moles of barium by Avogadro’s number
Two moles of barium = 2 * 6.022 * [tex]10^{23}[/tex] = 12.044 * [tex]10^{23}[/tex]

which components of the atom are found outside of the nucleus? responses electrons electrons neutrons neutrons all are found in the nucleus. all are found in the nucleus. protons
Electrons are the components of the atom that are found outside of the nucleus.
In contrast to protons and neutrons, which are found inside the atom's nucleus, electrons are found outside the nucleus. Negative electrons are drawn to the positive nucleus because their opposing electric charges attract one another. This force of attraction keeps electrons flowing continuously in the otherwise empty area surrounding the nucleus, this force of attraction keeps electrons flowing continuously.
Since they are so tiny, electrons. Since an electron's mass is only a tiny fraction of that of a proton or neutron (approximately 1/2000), it is almost entirely absent from the overall mass of an atom. Electrons have an electric charge of -1, which is equivalent to but in the opposite direction of the proton's electric charge of +1.
Since there are exactly as many electrons in an atom as there are protons, the positive and negative charges "balance out," leaving the atom electrically neutral.
