Answer:
C.
Explanation:
All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).
Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.
In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.
In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.
In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
The volume of a can can be determined by the equation
Volume = Area x Height
Volume = 40cm^2 x 12cm = 480cm^3
Answer:
Respiration
Explanation:
Food energy is chemical energy that animals (including humans) derive from food through the process of cellular respiration. Cellular respiration may either involve the chemical reaction of food molecules with molecular oxygen (aerobic respiration) or the process of reorganizing the food molecules without additional oxygen (anaerobic respiration).
Answer:In 2019, the United States consumed about 31.01 trillion cubic feet (Tcf) of natural gas.
