Why molecules are called homo atomic molecules or hetero atomic molecules?
Molecules are called homoatomic if they are composed of the same type of atoms (eg. O2, N2) and heteroatomic if they are composed of different types of atoms (eg. H2O, CO2). This classification helps distinguish between molecules based on their elemental composition.
Are the gaseous di-atomic molecules of the Elements different from the molecules of Compounds?
Yes. The diatomic molecules of the elements include primarily H2, N2 & O2; Examples of molecular compounds include: H2O, C2H5OH, NH3, CO2, DNA and sugar.
What is the molar mass of oxygen gas?
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
How many moles of molecules are there in 7.6 x 10 to the 24 oxygen molecules?
Given: 7.6 x 1024 O2 moleculesKnown: 1 mole O2 molecules = 6.022 x 1023 molecules O2 moleculesConvert molecules to moles.7.6 x 1024 molecules O2 x (1mol O2/6.022 x 1023 molecules O2) = 13 moles O2 (rounded to two significant figures)
How many molecules are in O2?
There are approx 6.02 X 1024 oxygen atoms. --> 5mol CO2 (2mol O2/ 1mol CO2)= 10 mol O2 Then Avagadro's number is used to calculate the number of atoms.... 10 mol O2 (6.02 X 1023/ 1mol) = 6.02 X 1024
Which one is hetero atomic molecules O2 or H2 SO4?
The sulfate molecule (SO4) is heteroatomic.
Which one is hetero atomic molecules NH3 or H2 SO4?
h2so4

In the equation 2 H2 plus O2 the H2 molecules are?
H is the atomic symbol for hydrogen, the 2 subscript means it is diatomic.
How many atoms are in 4 o2?
O2 has 2 atoms of oxygen.

How many oxygen molecules O2 are in 2.56 grams of O2?
The number of oxygen atoms is 0,188.10e23.

Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
The number of molecules in 48.0 grams of oxygen gas (O2) is?
To find the number of molecules in 48.0 grams of oxygen gas (O2), you first need to determine the number of moles of O2 using its molar mass (32 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. The calculation would be: 48.0 g / 32 g/mol = 1.5 moles of O2, and 1.5 moles x 6.022 x 10^23 molecules/mol = 9.033 x 10^23 molecules of O2.
How does the ozone hole form over Antarctica in Spring?
In the Spring, the earth tilts far enough toward the sun that the Chloroflorocarbons (CFCs) can be mobilized and become active. Once active, they attach themselves to the Oxygen molecules in the O2 gas -- ozone -- and the hole forms. A technical description from Wikipedia includes: "Ozone is formed in the stratosphere when oxygen molecules photodissociate after intaking an ultraviolet photon whose wavelength is shorter than 240 nm. This converts a single O2 into two atomic oxygen radicals. The atomic oxygen radicals then combine with separate O2 molecules to create two O3 molecules. These ozone molecules absorb ultraviolet (UV) light between 310 and 200 nm, following which ozone splits into a molecule of O2 and an oxygen atom. The oxygen atom then joins up with an oxygen molecule to regenerate ozone. This is a continuing process that terminates when an oxygen atom "recombines" with an ozone molecule to make two O2 molecules."
How many molecules of O2 does TiO2 contain?
Titanium dioxide (TiO2) contains no molecules of O2. It is composed of one titanium atom and two oxygen atoms in each molecule, but does not contain any molecules of molecular oxygen (O2).
What does O2 mean?
O2 is the chemical symbol for oxygen. if something has O2 in it it has 2 oxygen molecules=)
