What elements make up the compound C8H18?
The compound C8H18 is composed of carbon and hydrogen atoms. It is an alkane known as octane, with 8 carbon atoms and 18 hydrogen atoms in its chemical structure.
A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 gmole What is the molecular formula of this compound?
The molar ratio of hydrogen to oxygen in the compound is 2:1. To find the empirical formula, divide the moles of each element by the smallest number of moles, which is 0.059 mol for hydrogen. This gives a ratio of 1:0.5 for hydrogen and oxygen, which simplifies to the empirical formula H2O. To find the molecular formula, calculate the molecular mass of H2O (18 g/mol) and divide the given molecular mass (34 g/mol) by the empirical formula mass to get the multiplier of 2. So, the molecular formula of the compound is H2O2.
What is kerosenes chemical formula?
Kerosene is a mixture of hydrocarbons having 10 to 18 carbon atoms,.
What eliments are present in octane?
Since its chemical formula is C8H18, it contains 8 carbon atoms and 18 hydrogen atoms.
How many carbon atoms does it take to create three glucose molecules?
To create three glucose molecules, it would require a total of 72 carbon atoms because each glucose molecule contains 6 carbon atoms. So, 6 carbon atoms x 3 glucose molecules = 18 carbon atoms for each individual glucose molecule, and 18 carbon atoms x 3 = 72 carbon atoms in total.
What is the molecular formula for a 18 carbon alkane?
The molecular formula for an alkane with 18 carbon atoms is C18H38. Alkanes have the general formula CnH2n+2, where n is the number of carbon atoms.
How many atoms are in C13H18O2?
There are 33 atoms in C13H18O2. This is calculated by adding the number of atoms for each element: 13 carbon atoms, 18 hydrogen atoms, and 2 oxygen atoms.
Is octane an ionic compound?
No, octane is not an ionic compound. Octane is a hydrocarbon, specifically an alkane, which consists of carbon and hydrogen atoms bonded together through covalent bonds. Ionic compounds are formed by the transfer of electrons between a metal and a nonmetal.
Is C8H18 a alkane?
Yes, C8H18 is an alkane. It specifically corresponds to octane, a straight-chain hydrocarbon with 8 carbon atoms and 18 hydrogen atoms, which is commonly found in gasoline.
What is the molecular formula for argon?
The molecular formula for argon is Ar. Argon is a noble gas with atomic number 18 and does not typically form molecules like other elements.
What elements make up octane?
Octane is made up of carbon and hydrogen atoms arranged in a specific molecular structure called the alkane group. It consists of 8 carbon atoms and 18 hydrogen atoms. This molecular arrangement gives octane its specific chemical and physical properties, making it a common component in gasoline.
Which alkanes are solids at room temperature?
alkane is CnH2n+2. and any alkane with n= 18 and n>18 is solide. such as paraffin wax C18H38.
Which product has the largest molecular mass sodium acetate water or carbon dioxide?
Sodium acetate has a larger molecular mass than water or carbon dioxide. Water has a molecular mass of 18 g/mol, carbon dioxide has a molecular mass of 44 g/mol, and sodium acetate has a molecular mass of 82 g/mol.
which of the following is the correct model of C8H18?
just took the test
What is the combination of letters and numbers used to represent a substance?
A molecular formula contains the atomic composition by element and their quantities. For example H2O is the molecular formula for water. The formula indicates that there are two atoms of hydrogen (H) and one oxygen (O) in each water molecule. Through the molecular formula molar mass can further be derived. In the case of water is 18-grams per mole.
What is the ratio of carbon atoms to hydrogen atoms in a molecule of octane?
8 is not the answer because octane does no refer to the number of hydrogens but rather the number of carbons. c-c-c-c-c-c-c-c as you can see the number of hydrogens that would bond to the carbons is 18.-------The chemical formula of octane is C8H18, consequently the number of carbon atoms is 8.
How many total atoms are found in ibuprofen?
The molecular formula of ibuprofen is C₁₃H₁₈O₂. To calculate the total number of atoms, add the number of carbon, hydrogen, and oxygen atoms: 13 carbon atoms + 18 hydrogen atoms + 2 oxygen atoms = 33 atoms in ibuprofen.
