There is Lab about the birth rate reaction between acid and wire Mg HCl will be seen that this type of substances and 2 will be made, and then there is reaction between hydrogen gas, we bring this gas to write a graph, and then wrap it up when the time was up.But Mg wire will be reduced due to a metal reacts with an acid to decrease in volume, so when it is finished Lab teacher points to the end of exams, and then send me an hour enough to do so that it could feel good very happy.
