Oh, dude, you're hitting me with some chemistry now? Okay, so the 4 and 2 in 4H2 signify the number of hydrogen atoms in the molecule. It's like saying you have 4 apples and 2 Oranges, but in chemistry lingo. So yeah, 4H2 means you've got 4 hydrogen atoms hanging out together.
Well, darling, the "4" in 4H2 signifies there are four hydrogen atoms, and the "2" indicates there are two hydrogen molecules. So, in total, you've got yourself four hydrogen atoms and two hydrogen molecules in that little chemical formula. Hope that clears things up for you, sweetie.
In the chemical formula 4H2, the number 4 indicates the presence of four hydrogen atoms, while the number 2 indicates that each hydrogen atom is paired with another to form a diatomic molecule (H2). Therefore, the formula 4H2 represents a total of 8 hydrogen atoms bonded together in 4 H2 molecules.
The answer is (2-4)
x-2(x)+4/x^2 -4=x-2x+4/x^2 -4=-x-4+4/x^2
4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6 4!/(2!*2!) = 4*3*2*1/(2*1*2*1) = 6

2 root 4 = 2 x 2; -2 to the power 4 is 16 (-2/4/-8/16)
The little 2 in 4H2 indicates that there are two hydrogen atoms bonded in a molecule of 4H2. This notation is used in chemistry to represent the number of atoms of each element in a compound or molecule.
The meaning of 4 H2 is four molecules of hydrogen.
The "big 4" in 4H2 refers to the four hydrogen (H) atoms in the chemical compound. The "2" indicates that there are two molecules of the compound. Therefore, 4H2 represents a molecule composed of four hydrogen atoms.
To balance the equation 4H2 + 2C, we need to adjust the number of atoms on each side of the equation. Adding a coefficient of 2 in front of C on the left side will balance the carbon atoms. The balanced equation will be 4H2 + 2C2.
