Part a (7 points): how many grams of iron (fe) will be produced if you start with 3.65 liters of carbon monoxide gas (co) at stp? part b (3 points): jacob performed the above experiment in his chemistry class, and collected 4.23 grams of iron. what is the percent yield? fe2o3 + 3 co --> 2 fe + 3 co2                    for  

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.

Suppose that during that icy hot lab 65,000 j of energy were transferred to 450 g of water at 20°c what would have have been the final temperature of the water
