In methane a C atom is surrounded by 4 H atoms.Now about the angle. There are 6 tetrahedral angles i.e H-C-H angles..Imagine a C atom in the center.A H atom on top of it and 3 H atoms below forming a triangle(to make it look simple).Now start from the H atom on top,go through the C atom to an H atom below.This way you get 3 tetrahedral angles right??Now start from an H atom below the C atom and go to another H which is below the C atom via C atom(keep this H atom in mind).This way you get 2.Now for the last angle.Simple.Its the angle between the remaining 2 H atoms in the bottom.Hope you got it.
Mathematically,number of ways we can select 2 H atoms from 4. 4c2,which equals 6.
yes
2 structures are possible for a tetrahedral molecule with a formula of AHXYZ.
The molecule of methane has 5 atoms.
None
The chemical formula for methane is CH4. Then there are four hydrogen atoms and one carbon atom in each molecule, making two distinct types of atoms.
In one molecule of methane there are 10 (ten) protons.
There are many, but the most common is methane (CH4).
2 structures are possible for a tetrahedral molecule with a formula of AHXYZ.
The molecule of methane has 5 atoms.
There are many compounds that exhibit tetrahedral structure. Some of those compounds are carbon tetrachloride (CCl4), chloroform (CHCl3), and methane (CH4). Many compounds of carbon (those which don't contain double bonds) are tetrahedral in structure because carbon tends to form four single bonds.
None
Four. Ammonia (NH3) is an example.
The chemical formula for methane is CH4. Then there are four hydrogen atoms and one carbon atom in each molecule, making two distinct types of atoms.

In one molecule of methane there are 10 (ten) protons.
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
the chemical formula of methane is CH4. one molecule of methane contains one carbon atom and four hydrogen atoms.
Moles of methane. No half molecules, I think! 2.50 moles methane (1 mole C/1 mole CH4)(6.022 X 1023/1 mole C) = 1.51 X 1024 molecules of carbon --------------------------------------------
