Explosion ^^

Yesterday, we have a chemistry class. The lesson of Thermochemistry. This chapter is quite difficult chapter and the chapter many counts.

Anw, we conducted experiments on Eksoterm and Endoterm class this time.

for Eksoterm, the teacher made the experiment of sodium metal. He said, if this amount of sodium metal (for seed bow), then immersed in water in a small container, then a school and even the highway will explode! BOOOMMM! so, because avoiding it, the teacher was only envy sodium, just a little, then dip it in a test tube containing water. Previously, we were all told to back off and away. Within 3 seconds, changed to sodium fire explosive. The fire is huge, and then exploded. Then the teacher, told us to get out of the lab, because there Hidrogen gas. Actually, the gas was not dangerous, but disrupt the atmosphere.

 

Then, he had made an attempt to Endoterm. He uses the same materials from Ammonia Barium. "Dimasukkannya" into the test tube, and then shook. Then the tube was cold as ice, and when the father told us to kiss her, came out a very interesting smell served until making his nose hairs fall out. Odor wc! smells times! smell !!!!!!

 

okay lah... gtg. bye XD
