Explanation:
Carbon has four electrons in its outer most orbit and it can share four more electrons from other atom to complete its valency while oxygen has 6 electrons in its outermost orbit and it can either charge the electron or gain two electrons from other atom.
Therefore in , the carbon atom shares its two electrons with two electrons of each oxygen atom and forms double bond with it. Thus, total pairs of electron to be shared by the atom of the molecule is two.
Answer:
Explanation:
Wood has_chemical energy_____ energy while a burning fire has__heat energy __ energy
Wood is a material that makes up the central part of the trunk and branches of trees. Wood is made up of complex hydrocarbons and a rich cellulose network of organic molecules. A wood stores chemicals energy.
Combustion process such as burning liberates heat energy in them. Burning occurs in the presence of oxygen. As the oxygen combines with the materials, heat becomes liberated to the surroundings. Burning is an exothermic process in which heat energy is liberated.
Answer:
I think it's a I'm not sure though
If the temperature is increased, then the amount of oxygen released by the plant during photosynthesis will decrease. If the temperature is too high the enzymes lose their shape and become unable to function properly, and the rate of photosynthesis decreases.
I hope this helps in anyway!
