Can you arrange the numerals 1 to 9 (1, 2, 3, 4, 5, 6, 7, 8 and 9) in a single fraction that equals exactly 1/3 (one third)? Could someone explain how you get the answer to the problem, please don't just say the answer!
i was given an equation of H2SO4(1)+ Na2CO3(s)>>> Na2SO4(s)+CO2(g)+H2O(l) I tried plugging in numbers and I don't understand what I am supposed to do. the first beaker had 1g of Na2CO3 and added 20ml of 3M H2SO4 to the beaker. empty beaker 47.42g beaker with 1g an...
i have 2 questions stoichiometry loss of CO2 1. record the amount of CO2 produced vs the amount of Na2CO3. I did 7 beakers with 20ml of 3M H2SO4 and add varying amounts of Na2CO3 to each. 2. discuss your results in terms of moles. is there a linear relationship between the amo...
