Hydrogen Summary * This is how hydrogen fuel cells work: 1. Gas stored in tanks 2. Atoms reach anode 3. Become hydrogen ion and a free electron 4. Ion goes through electrolyte layer 5. Hydrogen ion passes‚ but free electron does not 6. Free electron runs through external circuit from anode (-) to cathode (+) 7. Current of electrons creates electricity 8. Hydrogen ion enters cathode and combines with oxygen to become water which is better for the ecosystem because

POTATO INTO BATTERY Abstract a.Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result It did go well and the potato did give voltage to the equipment (clock) However‚ the

mL of 1% hydrogen peroxide solution was made. In order to get this‚ the stock solution‚ which was 3%‚ was diluted using 10 mL of hydrogen peroxide and 20 mL of water. In the second beaker‚ a ¼ dilution of potato extract was made using 2 mL of potato extract and 6 mL of water. The third plastic beaker contained 8 mL of water. Using the first and second beaker the experimental assay was performed. Using forceps a small paper disk was dipped into the second beaker containing the potato catalase

the trend of each factor affecting on the enzyme activity is shown and described clearly. II. Hypothesis Experiment 1 (Effect of Temperature): As the temperature increases‚ the height of the bubble will increase too‚ indicating a faster rate of reaction. Experiment 2 (Effect of pH): Enzymes are affected by changes in pH. Extremely high or low pH values generally result in complete loss of activity for most enzymes. Experiment 3 (Effect of Substrate Concentration):

Along the way‚ scientists discovered that the popular staple of many people’s diets may also have potential to help power it as well. The potato is starchy‚ tuberous crop from the perennial nightshade . The word "potato" may refer either to the plant itself

Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

is collapses and the solid is converted into liquid. The trend in structure is from the metallic oxides containing giant structures of ions on the left of the period via a giant covalent oxide in the middle to molecular oxides on the right. Sodium peroxide‚ magnesium oxide and aluminum oxide are metallic oxide which have high melting and boiling point compared to other period 3 oxide. This is due to their giant ionic structure and the strong ionic bond. Strong ionic bond in the molecule need more energy

land of Bangladesh. In last few decades‚ the demand of potato is increasing rapidly. As a developing country‚ the people of Bangladesh are not so affluent. That’s why they prefer potato to rice or wheat. The demand of potato is thus increasing as it is cheaper than the other two horticultural product rice and wheat. Last year‚ the production of potato is massive. But‚ that huge production makes a little impact on the price level of potato. The price at the point of production is relevantly low

Potato Battery Chapter I: Introduction I. Background of the Study Do you have like 500 unused sacks of potatoes and don’t know what to do with it? Does your low class battery always die out on you at the exact moment you look at the last digit of you clock? If you answered yes‚ then here is the solution to your problem! Potato batteries are designed for you! So why do you spend so much money in buying new batteries for your digital clock if you can use the alternative resource. II. Statement
