10 million Kelvin and at that point there is enough temperature and enough pressure to overcome the coulomb forces‚ bringing the two protons close enough to each other for the fusion process (diagram below). This is called ignition because when two of the protons fuse the resulting nucleus has a slightly smaller mass. So the first stage of this there are two protons under enough pressure

are composed of particles called protons‚ electrons and neutrons. Protons carry a positive electrical charge‚ electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom‚ called the nucleus‚ and the electrons ’orbit’ the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. Protons and neutrons are both composed

Chromatography The Atomic Structure Atoms contain electrons which travel along electron shells‚ surrounding the nucleus that contains nucleons such as protons and neutrons. Electrons‚ neutrons and protons all make up an atom‚ they are called sub-atomic particles. Protons – has a relative charge of 1+ and a relative atomic mass of 1 Neutrons – are neutral‚ therefore the charge is 0. Also has a R.A.M of 1 Electrons – has a negative charge (1- )‚ and has a R

What is the project about: Students learn about gas and chemical reactions by discovering how to inflate a balloon using baking soda and vinegar. Also to be able to contest whether baking soda and vinegar alone will inflate a balloon faster than baking soda and vinegar with lemon juice. Question:Will Baking Soda and Vinegar or Baking Soda and Vinegar with lemon juice‚ blow up the balloon faster? hypothesis:I think that the baking soda and vinegar alone will blow up the balloon faster than the Baking

Cellular Respiration  Cellular respiration is the process of oxidizing food molecules‚ like glucose‚ to carbon dioxide and water. C6H12O6 + 6O2 + 6H2O → 12H2O + 6 CO2 The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis‚ the breakdown of glucose to pyruvic acid the complete oxidation of pyruvic acid to carbon dioxide and water In eukaryotes‚ glycolysis occurs in the cytosol.

Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

a) I definately agree with this statement and how science is ever changing. The scientific method begins by asking a question about something. After asking a question the next step is to form a hypothesis or educated guess. A repeatable expieriment is then created to test said hypothesis‚ and a large amount of data is collected. Data collection then leads Scientits to analyze the data and come up with a conclusion to see if the hypothesis was proven correct or incoreect. If the hypothesis is proven

GENERAL CHEMISTRY September 2011 GENERAL CHEMISTRY September 2011 ISOTOPES Atoms of a given element which have the same number of protons but different numbers of neutrons are called isotopes. Thus‚ isotopes have the same position in the periodic table‚ the same chemical properties and the same atomic charge. The simplest example of an atom with different isotopes is hydrogen. The three isotopes of hydrogen are shown here: The increasing number of neutrons in the nucleus of the hydrogen
