Saturated hydrocarbons are major components of gasoline.
What are saturated hydrocarbons?Alkanes are saturated hydrocarbons, chemical molecules with solitary carbon-atom bonds. Petroleum, natural gas, and coal contain them, as do many industrial and home items. Heating, cooking, and transportation employ saturated hydrocarbons, which burn easily. They are less reactive than unsaturated hydrocarbons because they lack double or triple bonds.
Saturated hydrocarbons are CnH2n+2, where n is the number of carbon atoms. Methane (CH4), a colourless, odourless gas, is the simplest alkane. Tetracontane (C40H82), a solid at ambient temperature, is the biggest. The structure and amount of carbon atoms of saturated hydrocarbons determine their physical and chemical characteristics.
Saturated hydrocarbons make polymers, rubber, and solvents. Lubricants, cosmetics, and pharmaceuticals utilise them. Saturated hydrocarbons emit greenhouse gases when burned, leading to global warming and climate change.

During combustion what type of chemical reaction takes place
2Na + 2H2O → 2NaOH + H2
How many grams of NaOH could you make with 8.0465 g of Na?
? g NaOH (use 5 sig fig
According to the stoichiometry of the given chemical equation, 13.9939 grams of NaOH would be made with 8.0465 g of Na.
What is stoichiometry?Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample. It is useful in balancing chemical equations and making solutions of different concentrations.As according to the given chemical equation 46 g sodium gives 80 g sodium hydroxide, thus, 8.0465 g of sodium will give 8.0465×80/46=13.9939 grams.
Thus, 13.9939 grams of NaOH would be made with 8.0465 g of Na.

Why does the sun seem to change position in the sky?
The first major contributor to the Sun's apparent motion is the fact that Earth orbits the Sun while tilted on its axis. The Earth's axial tilt of approximately 23.5° ensures that observers at different locations will see the Sun reach higher-or-lower positions above the horizon throughout the year.

2. When an atom loses an electron, it becomes a
_a._positive ion.
c. neutral ion.
b. negative ion.
d. neutral atom.
Answer:
A
Explanation:
Atoms of elements can lose or gain electrons making them no longer neutral, they become charged. A charged atom is called an ion. When an atom loses electron(s) it will lose some of its negative charge and so becomes positively charged. A positive ion is formed where an atom has more protons than electrons.
Write the full electron configuration of calcium.
152 2s22p6 352 4s2
Use the electron configuration to predict the most likely oxidation state of calcium?
(Explain your answer please)
Answer: [tex]1s^22s^22p^63s^23p^64s^2[/tex] , oxidation state = +2
Explanation:
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies.
The electronic configuartion of Calcium with atomic number 20 is :
[tex]Ca:20:1s^22s^22p^63s^23p^64s^2[/tex]
As calcium can easily lose its two valence electrons to attain stability , its oxidation state is +2.

Chemical equilibrium is relatively rare in living cells. An example of a reaction at chemical equilibrium in a cell would be
Answer:
(D) a chemical reaction in which both the reactants and products are not being produced or used in any active metabolic pathway
Explanation:
A) a reaction in which the free energy at equilibrium is higher than the energy content at any point away from equilibrium
B) a chemical reaction in which the entropy change in the reaction is just balanced by an opposite entropy change in the cellʹs surroundings
C) an endergonic reaction in an active metabolic pathway where the energy for that reaction is supplied only by heat from the environment
D) a chemical reaction in which both the reactants and products are not being produced or used in any active metabolic pathway
E) no possibility of having chemical equilibrium in any living cell
The correct answer for a reaction that describes chemical equilibrium in a cell would be a chemical reaction in which both the reactants and products are not being produced or used in any active metabolic pathway .
A reaction in chemical equilibrium is a bi-directional reaction in which both the reactants and the products are present in a stoichiometrically balanced way within the system at a given period of time under specific conditions.
From the definition, a reaction would be in equilibrium if
both the reactant and product are present but have ceased being producednone of the reactant or product is being used by another process within the cell.The correct option is, therefore, D

A gas has 1.2 L of volume, 1.8 atm of pressure and 264 K temperature. If both the
volume was doubled but the pressure was halved, what would the new
temperature be?
Your answer
Temperature does not change, remains 264 K
Further explanationGiven
V₁= 1.2 L
P₁ = 1.8 atm
T₁ = 264
Required
The new temperature
Solution
The volume was doubled = 2V₁ = 2 x 1.2 = 2.4 L(V2)
The pressure was halved = 0.5P₁ = 0.5 x 1.8 = 0.9 atm(P2)
Combined gas law :
P₁V₁/T₁=P₂V₂/T₂
Input the value :
[tex]\tt \dfrac{1.8\times 1.2}{264}=\dfrac{0.9\times 2.4}{T_2}\\\\T_2=264[/tex]

Ilsa showed her parents a trick she learned in science class. She used water to make ice cubes. Ilsa then placed some ice cubes in a glass containing a clear liquid. The ice cubes floated. She then placed some ice cubes in another glass that also contained a clear liquid. In this glass, the ice cubes sank to the bottom of the glass. Ilsa did not tell her parents that the first glass contained water while the second glass contained rubbing alcohol. What can you conclude from this information?
A.
The ice cubes changed their density.
B.
Water has the same density as alcohol.
C.
Water has a greater density than alcohol.
D.
Alcohol has a greater density than the ice cubes.
Answer:
C. Water has a greater density than alcohol.
Explanation:
From the experiment, it can be shown that water has a greater density than the alcohol.
The ice cube is able to float in the water because, the density of the ice is less than the density of the water.
Density of ice < Density of water
So, the ice cube sinks in alcohol because the density of the ice cube is greater than the density of the alcohol.
Density of ice > Density of alcohol
Therefore, we can assume that since the density of ice is greater than density of alcohol, then the density of water is greater than that of the alcohol.

1.Which form of energy is due to the motion of an object's particles .
A. thermal energy, B.chemical energy C.mechanical energy D.electromagnetic energy
Answer:
thermal
Explanation:
Thermal energy is due to the motion of an object's particles, due to the random movement of molecules in a system, thermal energy also known as random or internal kinetic energy is produced, hence option A is correct.
Atoms or molecules in motion are the source of thermal energy. An object's thermal energy rises as its temperature rises because the movement of its molecules or atoms accelerates. It is possible to transmit an object's thermal energy to another.
Thermal energy, also known as random or internal kinetic energy, is created when molecules in a system move randomly, as a result of the motion of an object's particles.
