Oxygen and hydrogen have subscripts of 2 in the chemical formula for water (H2O) because they combine in a ratio of 2:1 to form a stable compound. Each water molecule contains two hydrogen atoms and one oxygen atom.
To show that there are two hydrogen atoms and four oxygen atoms in sulfuric acid (H2SO4), the numbers are placed as subscripts next to the elements: H2SO4. This indicates that the ratio of hydrogen to sulfur to oxygen atoms in sulfuric acid is 2:1:4.
4 2 hydrogen and 2 oxygen
This is farely simple. The subscripts just tell you how many atoms of an element are in the compund. Like this: H20 - Water has 2 hydrogen atoms and 1 oxygen atom CO2 - Carbon Dioxide has 1 carbon atom and 2 oxygen atoms. hence the name carbon di(which means 2)oxide(oxygen). The numbers succeeding elements indicate the number of atoms of that particular element in the compound. For example, in H20, there are two hydrogen atoms and one oxygen atom. In H2SO4, there ar two Hydrogen atoms, one Sulfur atom and four Oxygen atoms.
The elements in hydrogen peroxide are hydrogen and oxygen.
The subscripts in the formula for ethane (C2H6) represent the number of atoms of each element in the compound. In this case, "C2" indicates there are 2 carbon atoms, and "H6" indicates there are 6 hydrogen atoms in one molecule of ethane.
To show that there are two hydrogen atoms and four oxygen atoms in sulfuric acid (H2SO4), the numbers are placed as subscripts next to the elements: H2SO4. This indicates that the ratio of hydrogen to sulfur to oxygen atoms in sulfuric acid is 2:1:4.
Oxygen and Hydrogen, along with Fluorine, Chlorine, Bromine, Iodine, and Nitrogen, to not exist naturally as single atoms. O2 stands for an oxygen molecule, which is made up of two oxygen atoms bonded together. H2 stands for two Hydrogen atoms bonded together. Sometimes atoms are bonded together for other reasons. This notation means the same no matter what the element. For example, Ca2 would stand for two calcium atoms bonded together.
In a chemical formula, a subscript is a number written to the right and slightly below the symbol for the chemical element. If the subscript is 1, it is not written. The subscripts for the chemical formula for water, H2O, are 2 for hydrogen and 1 for oxygen. The subscripts for the chemical formula for glucose, C6H12O6, are 6 for carbon, 12 for hydrogen, and 6 for oxygen.
4 2 hydrogen and 2 oxygen
They both contain 2 atoms?
The subscript for Hâ‚‚ is 2, indicating that there are two hydrogen atoms present in the molecule.
The subscript in the equation tells you how many atoms of that element there are in the reaction. For example: H20 --> H2 + O2 Before the reaction there are 2 hydrogen atoms and 1 oxygen (the subscript 1 isn't shown). After the reaction there are 2 hydrogen atoms and 2 oxygen atoms. Keep in mind that this is a skeleton equation and isn't balanced yet.
Subscripts indicate the number of the preceding element Ie. in H2O there are two hydrogens (H) and one oxygen (O) or in C6H12O8 there are six carbon (C) twelve hydrogen (H) and eight oxygen (O) The number of atoms of the same element in the molecule
The hydrogen peroxide is both oxidized and reduced, to produce water and elemental oxygen.
This is farely simple. The subscripts just tell you how many atoms of an element are in the compund. Like this: H20 - Water has 2 hydrogen atoms and 1 oxygen atom CO2 - Carbon Dioxide has 1 carbon atom and 2 oxygen atoms. hence the name carbon di(which means 2)oxide(oxygen). The numbers succeeding elements indicate the number of atoms of that particular element in the compound. For example, in H20, there are two hydrogen atoms and one oxygen atom. In H2SO4, there ar two Hydrogen atoms, one Sulfur atom and four Oxygen atoms.
The elements in hydrogen peroxide are hydrogen and oxygen.
2 hydrogen, one oxygen oxygen and hydrogen (2) Henceforth, H2O.
