Answer:
The initial temperature is 499 K
Explanation:
Step 1: Data given
initial volume = 12 cm3 = 12 mL
Final volume = 7 cm3 = 7mL
The final temperature = 18 °C = 291 K
Step 2: Calculate the initial temperature
V1/T1 = V2/T2
⇒with V1 = the initial volume = 0.012 L
⇒with T1 = the initial volume = ?
⇒with V2 = the final volume 0.007 L
⇒with T2 = The final temperature = 291 K
0.012 / T1 = 0.007 / 291
0.012/T1 = 2.4055*10^-5
T1 = 0.012/2.4055*10^-5
T1 = 499 K
The initial temperature is 499 K
According to Le Châtelier's principle, an increase in temperature favors the endothermic process. Since the reaction, which proceeds towards bromine chloride, is endothermic, the reaction would shift right, making more products.
The given reaction equation for photosynthesis whereby, in the presence of light energy from the Sun and chlorophyll, plants synthesize glucose from carbon dioxide and water. As water is present as a reactant, it doesn’t also appear on the ’products’ side of the equation. So:
Water + carbon dioxide > glucose + oxygen.
As glucose contains 6 carbon atoms, these must be obtained from 6 molecules of CO2. So, overall:
6CO2(g) + 6H2O(l) > C6H12O6(aq) + 6O2(g).
What is photosynthesis?
Photosynthesis is the process plants and other organisms use to convert light energy into chemical energy, which is later released through cellular respiration to power the activity of the organism.
Therefore, This is the equation for photosynthesis whereby, in the presence of light energy from the Sun and chlorophyll, plants synthesize glucose from carbon dioxide and water.
