Base your answer to the question on the information below. iron has been used for thousands of years. in the air, iron corrodes. one reaction for the corrosion of iron is represented by the balanced equation below. equation 1: 4fe(s) + 3o2(g) → 2fe2o3(s)in the presence of water, iron corrodes more quickly. this corrosion is represented by the unbalanced equation below. equation 2: fe(s) + o2(g) + h2o(image) → fe(oh)2(s)which choice is a balanced equation that uses the smallest whole-number coefficients for the reaction for corrosion of iron? 4fe(s) + 2o2(g) + 4h2o(image) image 4fe(oh)2(s)fe(s) + o2(g) + h2o(image) image fe(oh)2(s)2fe(s) + o2(g) + 2h2o(image) image 2fe(oh)2(s)2fe(s) + 2o2(g) + 2h2o(image) image 2fe(oh)2(s)
