Photosynthesis will produce oxygen gas that will be taken up by humans for respiration. Respiration will produce carbon dioxide that will be taken up by plants for photosynthesis. So both waste products will be recycled and reused so therefore an example of zero waste world
Use the D = M/V equation, in which Density can be found by dividing <em>Mass/Volume</em>.
To solve, first find a rectangular prism tub that is filled to a certain level. Next, place the rock inside to find the amount of displacement (or how high the water level goes up.) In this way, you can find the <em>volume of the rock</em>.
Next, solve for the Mass. This can be found by dividing the total weight from the gravitational pull. This would give you the mass.
Finally, to find Density, divide the Mass found with the Volume. This would give you your final answer

Ca, they only have two valence electrons, in order to become more stable, they would like to lose all of them
Answer:
Temperature and Heat Temperature is the measure of the thermal energy of a substance. The hotter an object, the greater the motion of its particles, and the greater the thermal energy. Heat is the transfer or exchange of thermal energy caused by a temperature difference.
