Which reaction occurs at the cathode of a galvanic cell that has the following an aluminum electrode in an electrolyte with aluminum ions and a zinc electrode in an electrolyte with zinc ions? The reduction potential for the reduction of Al^ 3+ =-1.68V V. The reduction potential for the reduction of Zn^ 2+ = -0.76 V.

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.

the answers would be

the first one and the second one
