The charge on an electron is equal to: (a) 1.6 × 10-19 C of -ve charge (b) 2.6 × 10-19 C of -ve charge (c) 1.6 × 10-22 C of -ve charge (d) 1.6 × 10-23 C of -ve charge

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?

Select the most likely product for this reaction: koh(aq) + co2(g) – ? k2co3(aq) + h2o(1) k(s) + h2(g) + o2(g) k(s) + co3(9) +h2
