shell. 11. a) Ionization energy decreases when atomic number increases. As Atomic Number increases, the number of electrons around the nucleus goes up also. As the size of the electron cloud increases, the outer electrons are more shielded from the protons, so it requires less energy to overcome the positive-negative attraction forces. b) Ionization energy increases across a period. The attractive force between the positive charge in the nucleus and the outer valence electrons is increased. c) Ionization

converted from one form to another. Nearly all the mass of the atom is concentrated in a tiny nucleus in the centre. The nucleus is composed principally of two sorts of particles: the proton which carries the positive charge and the neutron which is electrically neutral and has a mass slightly bigger than that of proton. Nuclear energy is the energy released from the nucleus of an atom. When a nuclear reaction occurs whether fission or fusion, it produces large amounts of energy. How Nuclear Energy

1a. State one conclusion about the effect of temperature on the rate of reaction? (1 mark) -An increase in temperature increases the rate of reaction aii. One reason why? (1 mark) -Because the volume of gas being produced at 40 degrees was more rapid than at 20 degrees. a(iii). Average rate (1 mark) -2 cm cubed per second (I think) 1 (b) two students should the student keep constant? (2 marks) -Mass of Marble Chips -Concentration of acid b ii.

inorganic orthophosphate. Both high-affinity (low Km and Vmax) and low-affinity (high Km and Vmax) carrying systems have been recognized and include H+/Pi vital membrane proteins that are able to transfer compounds via plasma membrane, while required proton gradient is established by plasma membrane H+-ATPases (P-ATPases). The Km values of high-affinity systems in plants and fungi occur in series from 1 to 10 µM, while the values for the endomycorrhizae also fall in this range. While the the Km values

Introduction This report focuses on Malaysia. Some of the key issues that I would like to highlight in this forum are: the influence of globalization on International Business Trade for Malaysia, the roles of ASEAN Free Trade Agreement (AFTA) policies for ASEAN trade collaboration and competition, the macro environmental factors that international business should focus upon before launching market expansion, the roles of government in supporting international trade such as Foreign Direct Investment

Role of Enzymes ¨. Catalysts that help a molecule breakdown faster. ¨. Catalysts speed up or slow down a biochemical reaction by increasing or decreasing the activation energy. Does not change in reaction. ¨. Enzymes bind to a substrate to form the enzyme substrate complex. When bound the enzyme has a specific job it was designed to do. Once the job is done, the substrate has become a product, and the enzyme moves along to the next substrate. ¨. If enzymes were

1-bromobutane. The 1H NMR further confirmed the identity of the alcohol. In the spectra, RM-08-Pp and RM-08-Pp(zoom), 2˚ and 1˚ alkyl groups were found. These are the only types of protons found in the identified alcohol structure. Also, with the knowledge of the 3-ethyl-3-heptanol structure, signals for specific protons can be determined. The only discrepancy in this experiment was the boiling point of the alcohol. The alcohol has a known
