Consider the combustion of isooctane , C8H18 2C8H18(l) + 25O2 begin mathsize 24px style rightwards arrow end style 16CO2 + 18H2O(l) ∆H = -10930 kJ

Calculate the energy released when 105 g of isooctane are combusted in excess oxygen

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
