Which period is older than the Triassic period? Cambrian Cretaceous Jurassic Paleogene.
Answers
The Triassic period is one of the geological periods and is the shortest of the Mesozoic era. Cambrian is the older era than the Triassic period.
What is Cambrian and triassic period?
The Triassic period existed 250 -200 million years ago and started after the vastest and most extreme devastation ever. It is the 1st period of the Mesozoic and is known for the movement of the Dinosaurs on the land, flying pterosaurs and swimming plesiosaurs and ichthyosaurs.
The Cambrian is the period of the Paleozoic era and is the most important period because of the appearance of many animals. In this period, the temperature raised on the planet and the ice sheets melted at a very dangerous rate leading to mass devastation.
Therefore, option A.Cambrian is older than the Triassic period.

According to reaction, 2 atoms of aluminum gas reacts with 3 molecules of chlorine gas.
Then 20 atoms of aluminum will react with :
of chlorine
Aluminum is a limiting reagent.
Molecules of chlorine left unreacted: 45 - 30 molecules = 15 molecules
Then 15 molecules of chlorine gas will react with :
of aluminum
10 more atoms of aluminum will required to use up all chlorine.
2:3 and an x. X is 30. 20/2 = 10 so an answer is
45/3 = 15. Both ratios are used
45 - 30 = 15 CL2 left.

Answer:
The answer is 8.00 moles
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
8.00 moles

pH=-log[H⁺]
pH=14-pOH
pOH=-log[OH⁻]
[H⁺]=K(w)/[OH⁻] (K(w)=1.01×10⁻¹⁴)
You can use any of those equation in what ever order to find the [H⁺] and then pH. If pH>7, the solution is basic. If the pH<7, the solution is acidic.
I will show you how I would find it but there is more than one way to do it.
[H⁺]=(1×10⁻¹⁴)/(10⁻¹¹)
[H⁺]=0.001M
pH=-log(0.0010)
pH=3.00
Therefore the solution is acidic.
I hope this helps. Let me know in the comments if anything is unclear.

Carbon is a naturally occurring element that can be obtained from various sources, both organic and inorganic. It is separated from other substances by Filtration, Distillation, and Chemical Reactions.
Carbon is the fourth-most abundant element in the universe and is a key component of all known life forms. Here are some common methods for obtaining and separating carbon from other substances:
Organic Sources: Carbon is a fundamental element in organic compounds, which are compounds containing carbon atoms bonded to hydrogen and other elements. Organic sources of carbon include:
Fossil Fuels: Coal, oil, and natural gas are rich in carbon. Carbon can be obtained from these sources through processes like combustion, pyrolysis, or gasification.
Biomass: Plant and animal matter, such as wood, leaves, and agricultural residues, contain carbon. Carbon can be extracted from biomass through processes like carbonization or fermentation.
Inorganic Sources: Carbon can also be obtained from various inorganic sources:
Carbonates: Minerals like limestone (calcium carbonate) and dolomite contain carbon in the form of carbonate ions. Carbonates can be thermally decomposed to release carbon dioxide gas, which can then be captured and processed.
Graphite and Diamond: These are naturally occurring forms of carbon. Graphite can be obtained from certain rocks and is used in various industrial applications. Diamonds, although much rarer, are another crystalline form of carbon.
Separation from Other Substances:
Filtration: If carbon is present in a solid mixture, it can be separated using filtration. A porous material (filter paper or a sieve) is used to separate solid carbon particles from other substances based on particle size.
Distillation: If carbon is mixed with liquids that have different boiling points, distillation can be used. The mixture is heated, and the component with the lower boiling point (liquid) vaporizes first, while carbon remains in the original container.
Chemical Reactions: Carbon can be separated from other substances through chemical reactions. For example, carbonates can be treated with acid to produce carbon dioxide gas, leaving behind other components.

Answer:
Carbon products are obtained by heating coal (to give coke), natural gas (to give blacks), or carbonaceous material of vegetable or animal origin, such as wood or bone (to give charcoal), at elevated temperatures in the presence of insufficient oxygen to allow combustion.

Answer:
FALSE
Explanation:
Assuming that the gas is ideal
Therefore the gas obeys the ideal gas equation
Ideal gas equation is
P × V = n × R × T
where
P is the pressure exerted by the gas
V is the volume occupied by the gas
n is the number of moles of the gas
R is the ideal gas constant
T is the temperature of the gas
Here volume of the gas will be the volume of the container
Given the volume of the container and number of moles of the gas are constant
As R will also be constant, the pressure of the gas will be directly proportional to the temperature of the gas
P ∝ T
∴ Pressure will be directly proportional to the temperature
