Answer:
Easy portability,easy convertability, high calorific value for its unit mass.
Explanation:
Oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.
What is oil?Any chemical compound that is nonpolar, predominantly hydrocarbon-based, hydrophobic, and lipophilic is considered to be an oil. Typically combustible and surface active, oils. Most oils are lipids which become liquid above room temperature and are unsaturated. Classes of chemical substances that may be unconnected in structure, characteristics, and usage are included in the general concept of oil.
They are employed in the production of numerous varieties of paints, plastic bottles, and various other products, as well as for usage as food (such as olive oil), fuel (such as heating oil), lubricant (such as motor oil), and medical uses. Some religious rituals and ceremonies employ specially formulated oils as cleansing elements. Oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.
Therefore, oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.

What is the ratio of the effusion rate of the helium to methane? (round to hundreds)
Answer:
2.00
Explanation:
From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.
Let the rate of effusion of Helium be R1
Let the rate of effusion of Methane be R2
Let the molecular mass of Helium be M1
Let the molecular mass of Methane be M2
Hence;
R1/R2 = √M2/M1
R1/R2 = √16.0294/4.0026
R1/R2 = 2.00
How can scientists use stoichiometry to ensure that commercial products contain the components that manufacturers claim they do?
Answer:
I know you have been waiting awhile for this question to be answered :)
Stoichiometry is used in industry quite often to determine the amount of materials required to produce the desired amount of products in a given useful equation. Each one of these products requires stoichiometry. There would be no products from these industries without chemical stoichiometry.
Explanation:
Hopefully this helps :D
Sorry you had to wait so long :(

What is the formula of a compound that has [1 mol Fe], [1 mol Ti], and [3 mol O]
Answer: [tex]FeTiO_3[/tex]
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
The molecular formula for a compound that has [1 mol Fe], [1 mol Ti], and [3 mol O] will be [tex]FeTiO_3[/tex]

Explanation:
Why are large differences in temperature between the wet bulb and dry bulb thermometers are possible only at higher temperatures?
Answer:
At constant vapor pressure, the relative humidity decreases as the temperature increases, therefore, at higher temperature the relative humidity is low and water readily evaporates from the wet bulb thermometer that results in the cooling of the bulb such that at a given ambient temperature the very low relative humidity results in very large differences between the temperatures of the wet bulb thermometer and that of the dry bulb thermometer and the wet bulb is observed to be the colder thermometer of the two

what are buffers and why are they important
Explanation:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base,thus maintaining the pH of the solution relatively stable.This is important for processes and/or reactions which require specific and stable pH ranges.

Magnesium bromide (one magnesium atom with two bromine atoms) has a
chemical formula of MgBrz. If you look at the total atomic mass of MgBr2,
does magnesium or bromine make up more of the mass?
they are exactly the same
it is impossible to tell
magnesium
bromine
Answer:bromine
Explanation:
The mass of magnesium is 24 whereas 1 bromine atom is 80 (rounded up from 79.9) and there is 2 bromine atoms which means you have to multiply 80 by 2, giving you 160.
