If a chemical reaction such as photosynthesis begins with 6 atoms of carbon c , how many atoms of carbon c should be in the products? a. 12 atoms of carbon cb. 6 atoms of carbon cc. 3 atoms of carbon cd. 2 atoms of carbon c

Option B. 6 atoms of carbon

Explanation:

In any chemical reaction, atoms from reactant side and product side must be the same.

This is photosynthesis reaction:

6CO₂  + 6H₂O  →  C₆H₁₂O₆  +  6O₂

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
