Types of chemical reactions based on the properties of water Problem Find the mass of glucose and the volume of oxygen circulating in the process of photosynthesis, if 448m3 of carbon dioxide entered the reaction. Calculate the amount of water that was required for this.

1.2 H2O = 2H2 + O2 (decomposition)
2.2Na + 2H2O = 2NaOH + H2 (substitution)
3.CO2 + H2O = H2CO3 (compound)
4.FeS + 2H2O = Fe (OH) 2 + H2S (exchange)
A task.
1) The equation of photosynthesis: 6СО2 + 6Н2О = С6Н12О6 + 6О2.
2) Mr (C6H12O6) = 180
3) 1m3 = 1000l, which means 448m3 = 448000l
4) According to the equation, 180 g of glucose is formed from 6 * 22.4 liters of CO2, which means from 448000 liters – xg.
x = 448000 * 180/6 * 2.4 = 600000g or 600kg.
5) the amount of consumed CO2 – n = 448000 / 22.4 = 20000 mol, according to the equation n (CO2) = n (H2O)
Answer: m (C6H12O6) = 600 kg, n (H2O) = 20000 mol.
