Answer:
Different
Explanation:
The chemical properties of a compound are entirely different from the chemical properties of its constituent elements. This is because of the atomic forces that came into being in a molecule.
For instance sodium and salt of NaCl possess entirely different properties.
Answer: Stochiometric coefficients
Explanation: The chemical equations must be balanced to follow the law of conservation of mass which says that the mass of products must be same as the mass of reactants.
![CH_4+O_2\rightarrow CO_2+H_2O](https://tex.z-dn.net/?f=CH_4%2BO_2%5Crightarrow%20CO_2%2BH_2O)
This is a skeletal equation and needs to be balanced by adjusting the stochiometric coefficients. In order to keep the mass same, the number of atoms must be same on both sides.
![CH_4+2O_2\rightarrow CO_2+2H_2O](https://tex.z-dn.net/?f=CH_4%2B2O_2%5Crightarrow%20CO_2%2B2H_2O)
Answer:
loses electrons and loses potential energy.
Explanation:
A reducing agent looses electrons in an oxidation-reduction reaction. Oxidation is defined as the loss of electrons.
Reducing agents are oxidized in an oxidation-reduction reaction. When a specie looses electrons, it also looses energy. Hence the answer given above.
Answer:
The correct answer is A
Explanation:
Hydrogen, oxygen, chlorine are the most abundant elements in oceans.
Oxygen is 85.84% by mass
Hydrogen is 10.82% by mass
Chlorine is 1.94% by mass
