วันนี้มีคาบเคมี ครูให้ทำ lab เกี่ยวกับอัตราการเกิดปฏิกิริยาระหว่างลวด mg และกรด hcl จะเห็นว่าสารทั้ง 2 ชนิดนี้จะทำปฏิกิริยาระหว่างกันแล้วมีแก๊สไฮโดรเจนเกิดขึ้น We bring this gas to a graph.Volume of hydrogen gas will increase with the wire because mg is reduced to a metal reacts with acid. The volume decreases. So when doing a test lab the teacher was collected and then sent me the hours I do feel better.

Today, there are lessons, teacher Chemistry Lab on the rate of reaction between Mg and HCl acid wire to see whether the two substances of this type will react with hydrogen gas, and between each other. We take this writing gas in a graph. The volume of hydrogen gas will rise by wires, but Mg is reduced due to a reaction with the acid. Keep the volume down, so when the Lab was a teacher, and then send the final hour test I scored enough to make it feel good.

Today there is an unlighted Lab chemistry teacher, about the birth rate reaction between acid and wire Mg HCl will see that this type of terminal 2 and will make interaction hydrogen gas, and then there is the gas, we write this as a graph.Volume of hydrogen gas will increase, but a wire Mg will be reduced due to a metal reacts with an acid to decrease in volume, so when it is finished Lab teacher exams, keep the end of an hour, and then send me your points as soon as possible so I feel the best.
