There are three hydrogen atoms in an ammonia molecule.
There are twice as many hydrogen atoms as oxygen atoms in a polysaccharide. The general formula for this is Cx(H2O)y.
Carbohydrates fall into the general formula Cx(H2O)y, each molecule containing carbon, hydrogen, and oxygen atoms.
The number of hydrogen atoms is twice the number of oxygen atoms. Glucose is C6H12O6, so there are 12 hydrogen atoms for every 6 oxygen atoms in a molecule.
There are twice as many hydrogen atoms as oxygen atoms in a polysaccharide. The general formula for this is Cx(H2O)y.
energ y is absorbed by the molecule to increase its kinetic energy
the ratio in water is two hydrogen to 1 oxygen. In carbohydrates, the empirical formula is Cx(H2O)y where x=y=1 in monosaccharides.
There are two possible structures for a square planar molecule with a formula of AX3Y. In one structure, the Y atom is in the center and the three X atoms are arranged around it. In the other structure, one of the X atoms is in the center and the Y atom and the other two X atoms are arranged around it.
Let x = hydrogen gas 532 / 2 = x / 3 .... x = 798L Let y = nitrogen gas 532 / 2 = y / 1 .... y = 266L
Correct: ''the atoms of the element X are isoelectronic with the ions of the element Y".
When two hydrogen atoms combine to form a helium atom, a process called nuclear fusion occurs. This releases a large amount of energy in the form of light and heat. This is the same process that powers the sun and other stars.
A molecule of a compound must be electrically neutral overall. There is only one y atom in the formula, so that the total contribution of charge from y is +2. There are two x atoms, and each of them must have an oxidation number of -1 for a total of -2 to neutralize the charge from y.
It depends on what x and y are.
