Answer:
Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
Explanation:
3.84 - 1.43 = 2.41
2.41g of table sugar
% mass = ( (mass of element) / (total mass) ) * 100
% mass = (2.41 / 3.84) * 100
% mass = (0.6276) * 100
% mass = 62.76
62.76%
The law of conservation of energy is that energy cannot be created or destroyed, but it can be transferred or transformed from one form to another (including transformation into or from mass, as matter). The total amount of energy in a closed system never changes. energy in a system may be transformed so that it resides in a different state.
Behavioral Adaptation is something that is natural in animals that are used for survival. Example: Birds Migrating north during the winter.
Chadwick discovered the existence of neutrons which accounts for isotopy.
Isotopes exists because atoms of the same element may differ in the number of neutrons present in each one. This phenomenon is called isotopy.
Chadwick discovered the existence of isotopes by bombarding Beryllium with alpha particles obtained from Polonium decay.
The discovery of the existence of neutrons led us to the a better understanding of isotopes since isotopes differ only in the number of neutrons present.
