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

with a non-metal substance it forms covalent bonds‚ which make molecules. The metal becomes positively charged atoms‚ which means that the number of electrons is never less than the number of protons. Non-metals become negatively charged atoms‚ and now the number of electrons is more than the number of protons. When atoms share electrons of nonmetals then a covalent bond is formed inside the molecule. Monatomic elements are elements that only contain one type of atom. An example of this would be the
Free Atom Electron Electric charge
Atoms are made up of three particles: protons‚ neutrons and electrons. Protons and neutrons are heavier than electrons and reside in the center of the atom‚ called the nucleus. And the electrons can be found orbiting around the atoms outer shell. Atomic number = to the number of protons found in the nucleus. Atomic weight = the total mass of protons and neutrons in an atom. 3. Valence: Is the number of free electrons in an atoms outer shell

Question 2.1: (i) Calculate the number of electrons which will together weigh one gram. (ii) Calculate the mass and charge of one mole of electrons. * ------------------------------------------------- Answer (i) Mass of one electron = 9.10939 × 10–31 kg Number of electrons that weigh 9.10939 × 10–31 kg = 1 Number of electrons that will weigh 1 g = (1 × 10–3 kg) = 0.1098 × 10–3 + 31 = 0.1098 × 1028 = 1.098 × 1027 (ii) Mass of one electron = 9.10939 × 10–31 kg Mass of one mole of

Nuclear Power Debate Year 11 Physics Gurjyot Singh Australia currently has no nuclear facilities generating electricity‚ which is forcing the Australian Government to look towards nuclear energy as a great alternative. Nuclear energy is a growing controversial topic in Australia; because the demands of utilizing electricity are increasing rapidly. According to a recent study‚ Australia has 23% of the world’s uranium deposits and is the second largest producer of uranium
