balance and often I can’t get enough power behind the shot. Whilst shooting you must be aware of the defender‚ they will try to rebound your shot. I sometimes don’t stand up very tall and so the goal defender is able to mark my shot very well. For example in a 1st team match against Pocklington the defenders were extremely tall and they could mark all of my shots with ease‚ they were able to rebound my shot off their hands and stop the ball reaching the net. I also have the tendency to place both my

Nuclear Chemistry Nuclear science is the study of sub-atomic particles and their function in various subjects. A nucleon is the collective name for the two components of the atomic nucleus: the neutron and the proton. Isotopes are any of the different forms of an element each having different mass numbers‚ which give the total number of nucleons. The major fundamentals of nuclear chemistry include radioactive decay‚ the nature of fission and fusion‚ and mass defect. The decomposition of the

The topic continues by looking at whether climate change will lead to extinction of species or evolution by natural selection‚ and looks at the evidence for global

between the two metals in the metal sulfate solution of the electrolyte. In order for a chemical reaction to take place‚ the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing the concentration of the anode‚ zinc sulfate‚ will increases the rate of reaction for oxidation because there are more zinc ions in the new concentration‚ which would also increase

The Inorganic Chemistry of Carbon Inorganic Carbon For more than 200 years‚ chemists have divided compounds into two categories. Those that were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

Hypothesis: If I increase the concentration of NaOH from 0.5M to 1M‚ then I will see the temperature slope increase in the reaction with an increased concentration because with an increase of moles‚ the particles will be colliding more often‚ therefore increasing the probability that the proper energy and alignment will occur to create more collisions in the same amount of time. Methods: List of Materials: • 110 mL of NaOH at 1 M (10 mL per run) • 110 mL of NaOH at 0.5 M (10 mL per run) • 220 mL

Reactant Can Affect the Rate of Reaction Aim To plan an investigation that allows me to measure the effect of increasing the concentration of a reactant on the rate of reaction. With the results generated‚ it is also hoped to draw accurate conclusions and explain the results using scientific knowledge. Introduction Some reactions are fast‚ for example neutralisation or burning magnesium in air to produce magnesium oxide. However‚ other reactions can be slow‚ for example‚ rusting of iron or souring

As high portions of the educated were exiled or killed‚ technological growth was choked. This increased rates of unemployment had an undeniably negative impact on the majority of victims in the Soviet Society also it affected the industrial growth of the Soviet as it also was damaged.
