the activation energy‚ or Ea. The size of this activation energy is different for different reactions. If the frequency of collisions is increased the rate of reaction will increase. However the percent of successful collisions remains the same. An increase in the frequency of collisions can be achieved by increasing the concentration‚ pressure‚ surface area‚ temperature and the addition of catalysts. Different reactions can happen at different rates. Reactions that occur slowly have a low rate of reaction

The United States government is divided into three different branches: Executive‚ Legislative‚ and Judicial. Each of the three branches checks the others in order to make sure no one branch gets too much power. The legislative branch introduces all the laws‚ and is referred to as Congress. Congress is divided into two parts‚ the Senate and the House of Representatives. The executive branch is in charge of enforcing the laws and can even introduce new policies and reforms. The branch consists of the

to magnesium hydroxide (Mg(OH)2)‚ and this coating will prevent further reaction. Therefore‚ in the heater meal‚ iron is added to the magnesium‚ leading to the production of a local cell – small-scale corrosion that happens where two metals of different reactivity are in contact under humid conditions – which speeds up the exothermic reaction. Because the electron potential of magnesium is lower than that of iron (the less reactive metal)‚ electrons will pass from the magnesium to the iron‚ and

Just imagine being forced into a rail car knowing that you are on your way to the place you are going to die‚ the scared feeling that you may never see your family or friends again is the way that millions of Jewish people felt during the Holocaust on their way to the Auschwitz concentration camps.
