The energy released by a chemical reaction can be measured using a calorimeter. When barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00g of water in the calorimeter decreases from 30.0⁰C to 8.0⁰C. If the specific heat of liquid water is 4.19J/g.⁰C, how much energy was absorbed by the reaction?​

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.

it is stable as it is in group 0 which have full outer shells of electrons
