the law of definite proportions
no. Carbohydrates contain carbon, hydrogen, and oxygen.
ch20
The mass of the oxygen and hydrogen that react to form water will be exactly equal to the mass of the water produced.
particles made up of 2 hydrogen n 1 oxygen
Oxygen and Hydrogen
Carbon, Hydrogen, and Oxygen ine the ratio of 1:2:1
Hydrogen and oxygen are the products of electroysis of water .
Quantitative means having numbers and measurements. qualitatitive does not. Qualitative Example: mix hydrogen and oxygen and you get water. Quantitative Example: mix two moles of Hydrogen and one mole of Oxygen to get one mole of water.
That statement is false.
Water consists of two hydrogen atoms and one oxygen atom.
In theory, the energy produced by creating four oxygen-hydrogen bonds after breaking two Oxygen-oxygen and hydrogen-hydrogen bonds in the reaction O2 + 2H2 -> 2H2O (hydrogen combustion in oxygen) is exactly the same than the energy needed to break four oxygen-hydrogen bonds to create two oxygen-oxygen and hydrogen-hydrogen bonds in the reaction 2H2O -> O2 + 2H2 (water electrolysis) However, you will always have great energy loss during electrolysis (an important part of your energy will be used to warm up your water) and in getting back your energy from your oxygen and hydrogen gas (a combustible battery or a motor will warm up too).
Hydrogen and Oxygen The scientific formula is H20 Meaning 2 hydrogen, 1 oxygen
