Part I: Record your observations. NaOH was dissolved in MgCl2‚ the color turned dark pink (from white) Questions In Part I the reaction you observed was Mg(OH)2 (s) Mg2+ (aq) + 2 OH- (aq). Compare the colors you observed in the experiment and answer these questions: A. Which way should the equilibrium shift when HCl is added? How do your results support your answer? It should shift to the left because adding any component causes the equilibrium to shift to the opposite side

seem more suitable than hydrogen. The possibility of hydrogen as a fuel is ever increasing‚ with the advantages outweighing the disadvantages more every year. Car manufactures are already making cars that are hydrogen powered‚ although they are either prototypes or extremely limited production runs‚ but cars such as the Honda Clarity prove that hydrogen powered cars really are not a thing of the future‚ but a thing of the present.

that way if you believe in the power of change. Hydrogen fuel is that change for the automobiles of the future. Hydrogen has been used for decades‚ but mostly for commercial use. Each year‚ we get closer to removing the oil company’s choke hold on our wallets. It’s time to drive with a lighter purse and a cleaner environment and it’s time for hydrogen fuel. The two largest points of debate with hydrogen fuel are cost and production Hydrogen fuel is a cheaper alternative to our current source

IRON (METAL) Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole‚ forming much of Earth’s outer and inner core. It is the fourth most common element in the Earth’s crust. Iron’s very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars‚ Like other group 8 elements‚ iron
