Green plants use light from the sun to drive photosynthesis. photosynthesis is a chemical reaction in which water and carbon dio
Korolek [52]

<span>The equation that represents the process of photosynthesis is: </span>

<span>
</span>

<span>6CO2+12H2O+light->C6H12O6+6O2+6H2O</span>

<span>
</span>

<span>Photosynthesis is the process in plants to make their food. This involves the use carbon dioxide to react with water and make sugar or glucose as the main product and oxygen as a by-product. Since we are not given the mass of CO2 in this problem, we assume that we have 1 g of CO2 available. We calculate as follows:</span>

<span>
</span>

<span>1 g CO2 ( 1 mol CO2 / 44.01 g CO2 ) ( 12 mol H2O / 6 mol CO2 ) ( 18.02 g / 1 mol ) = 0.82 g of H2O is needed</span>

<span>
</span>

However, if the amount given of CO2 is not one gram, then you can simply change the starting value in the calculation and solve for the mass of water needed.

HELPPPPPPPP!!!!!
lana [24]

Answer:

To calculate the theoretical yield, determine the number of moles of each reactant, in this case the sole reactant ethanol. Convert the 100 g to moles; the molecular weight of ethanol is 46 g/mole, therefore: Since there is only one reactant, it is also the limiting reagent.

City

<u>Explanation:</u>

The best analogy to explain the functions performed by a cell is by comparing it to a city.

Just like the city performs a multitude of task by housing critical elements like powerhouse, restaurants, transportation else, same way cell to performs similar functions for the body.

E.g.

  • In cell “Mitochondria” provides it with energy or the power in the same way “powerhouse” provides power to the city
  • Golgi bodies work as a car for transporting proteins to other parts of the cell.
