LB 171 Lecture Notes - Lecture 2: Silicon Tetrafluoride, Sodium Hydroxide, Heart Failure
Document Summary
Please discuss and answer these problems in groups of three. Each person must write a portion of the worksheet. Use the back of the worksheet for additional space. Balance the following equations: b2o3(s) + naoh(aq, ch3nh2(g) + o2(g, casio3(s) + hf(g) Nitroglycerine, (c3h5n3o9), is an explosive liquid used in dynamite. It also has a medical application to treat heart conditions such as angina and chronic heart failure. It can be prepared according to this unbalanced chemical equation: ____c3h8o3 (s) + ____hno3 (aq) ____c3h5n3o9 (aq) + ____h2o (l) 14. 98 g c3h8o3 was dissolved in 147. 0 ml of water and added to 154. 2 ml of a 0. 901 m hno3 solution. P4 can be formed from the following unbalanced equation: Ca3(po4)2(s) + sio2(s) + c (s) p4(g) + casio3(l) + co(g) 10. 34g of ca3(po4)2, 2. 76 g of sio2(s) and 0. 997 g of carbon were reacted together.
