Answer: concentration of solutions are expressed in various ways mol/L, mol/dm3, g/L etc
Explanation:
Number 4 is
-Oxidation occurs at the anode, while reduction occurs at the cathode. Recharging a battery involves the conversion of electrical energy to chemical energy. During recharging, there is movement of electrons from an external power source to the anode, and on the other side electrons are removed from the cathode.
Answer:The oxygen during photosynthesis comes from split water molecules. During photosynthesis, the plant absorbs water and carbon dioxide. After the absorption, the water molecules are disassembled and converted into sugar and oxygen.
Answer:
(C) The average molecular speed of ethane is equal to the average molecular speed of propanol.
Explanation:
When dealing with gases, you know that the temperature and speed are related. When held at a constant temperature, the speed is also held constant. We also know that ideal gases behave the same despite their identities.
Natural: Land mounds, Rivers
Human made: Country borders, cities
