Magnesium - aluminium alloys are widely used in circraft
construction. one particular alloy contains 70.0% al and
30.0% mg. how many grams of halg) are produced in
the reaction of 0.710g samples of this alloy with excess
heleg?
2 alig + 6hcl(aq) – 2 acc( 3 lags + 3h2 lg)
mg(s) + 2hcl(aq) - mg cl2 lag) + h2 lg)

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.
