Magnesium reacts with hydrochloric acid to produce magnesium chloride and hydrogen. In
another investigation, a student reacted 20cm
of hydrochloric acid with a concentration of
1.5 mol dm-3 with excess magnesium.
1) Write a balanced chemical equation for the
reaction.
11) Calculate the number of moles of hydrochloric
acid used.
111) Determine the number of moles of magnesium
chloride produced.
iv) Calculate the mass of magnesium chloride
produced.

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.
