<b>Thesis Statement</b><br>The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb‚ which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT.<br><br><b>The Hydrogen Bomb</b><br>The Atomic Bomb Was A Essential

Hydrogen Automobiles The effect of pollution that is emitted from vehicles is a serious concern in today ’s society. The cause of this pollution is the toxic emissions from current vehicles. This toxic emissions or pollution destroys the Earth ’s ozone layer or atmospheric gases Acknowledging these facts‚ many are very concerned with the condition of the Earth ’s atmospheric gases in the future. In just a very short time‚ scientists produced a new vehicle which only emits water out of its exhaust

bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war‚ the U.S wanted something bigger and stronger. In 1950‚ President Harry S. Truman announced work on the hydrogen bomb. A group of scientists led by Edward Teller created the first hydrogen bomb in

bonded to make one product causing an anabolic reaction. There are five factors that effect enzyme activity. They are: ·Temperature ·pH ·Inhibitors ·Substrate Concentration ·Enzyme Concentration The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato‚ you make more Catalase molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between

meter (N/m2)‚ or pascals (Pa). 3. Slowly drag the temperature (T) slider back and forth. (Note: In this Gizmo‚ the Kelvin scale is used to measure temperature. On the Kelvin scale‚ 0 degrees is absolute zero‚ the coldest possible temperature. Absolute zero is equal to -273.15 °C or -459.67 °F) A. How does the change in temperature affect the speed of the molecules? __If the temperature is colder the molecules move slower and if the temperature is hotter the molecules move faster.

Boiling point is the temperature at which the vapor pressure of the liquid is equal to the external pressure on the liquid and the liquid changes into a vapor. Melting point is the temperature at which the lattice 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.

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
