20 pts!! The theoretical yield of MgSO4 is expected to be 8.770 g, however, when the reaction is finished, only 4.77 g MgSO4 is actually formed. Calculate the percent yield of this reaction and write your numerical answer in the correct sig figs. (dont write the % symbol, only the number)

Fill in the blanks for the following statements: the rms speed of the molecules in a sample of h2 gas at 300 k will be times larger than the rms speed of o2 molecules at the same temperature, and the ratio µrms (h2) / µrms (o2) with increasing temperature. a not enough information is given to answer this question b sixteen, will not change c four, will not change d four, will increase e sixteen, will decrease
