I originally did a preliminary test with Iron wool where we used a similar method but Test the iron wool was held over the flame by tongs and not contained within a crucible. We learnt from this experiment the importance of the crucible to contain all of the metal for an accurate test because the iron wool broke off as it heated and we were left with a lot of the iron wool on the bench mats around the Bunsen burner so our calculation of the mass of iron oxide was not accurate as we had not contained

1 Introduction. Let us consider a triangle of fractions: Obviously‚ the numbers are following some pattern. In this investigation we will try to explain the theory behind this arrangement and to find a general relation between the element’s number and its value. The pattern above is called a Lacsap’s Triangle‚ which inevitably hints at its relation to another arrangement - Pascal’s Triangle (as Lacsap appears to be an anagram of Pascal). The algorithm behind it is very simple: each element

of the mast from the point on the ground O tan θ = A 20 ◦ tan 34 = y 20 y = tan 34◦ y = 6 × tan 55◦ =⇒ y = 29.7m 1d.p. 4. An isosceles triangle has base 8cm and sloping sides both with length 10cm. What is the base angle of this triangle? Solution Split the base of the isosceles triangle in half. We now have a right-angled triangle of base 4cm and hypotenuse 10cm. We can now find the angle θ as follows A H 4 cos θ = 10 4 = 66.4218... = 66◦ to the nearest degree. 10 cos

In our experiment we will be using the precipitation form which isolates an ion in a solution by a precipitation reaction‚ filtering‚ purifying by wash method‚ conversion to product of known composition‚ and final weigh of the product comparing the mass

epidemiological triangle focuses on the three primary factors that directly effect the “what”‚ “who”‚ and “where” of diseases (Ferng‚ 2011). One of these factors is the disease agent and its characteristics‚ the host and the host’s vulnerability to the disease‚ and the environment that surrounds the agent and host (Ferng‚ 2011). It is crucial to examine these components and how they interrelate to reach a better understanding of the disease. In one corner of the epidemiology triangle for obesity there’s
