Science Lab- Determining the Most Effective Antacid Robby Grewal SNC2D0 Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment‚ we will be using three liquid antacids which are Phillips Milk of Magnesia‚ Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing

EXECUTIVE SUMMARY One of the most important tasks that a petroleum engineer has to undertake is determining how much hydrocarbons are contained in a potential reservoir. Key physical characteristics that they will be concerned with include porosity‚ permeability‚ net-to-gross ratio and bulk rock volume. This information can then be used to calculate original oil in place (OOIP) and original gas in place (OGIP). Hence‚ for a given exploration prospect‚ explorers and commercial analysts can

Paragraph 1 Perovskite‚ with a general formula of ABO3‚ has a structure comparable to that of ReO3. What differentiates them is the fact that ReO3 lacks the cation A at its unit cell centres. An octahedron made up of six oxygen atoms encompasses each rhenium atom‚ and it forms the 3-dimensional structure by connecting its corners with other octahedral. At low temperatures and a pressure of about 3kbar‚ the Fermi-surface cross sections undergo nonlinear patterns. ReO3 thus undergoes phase transitions

I. Abstract This experiment aimed to determine the composition of Ni2+- ethylenediamine (en) complexes through Continuous Variations method as well as the number of ligands (n values). This nondestructive method is preferred in determining the amount of complexes present which will also not disrupt the equilibria. 0.3M concentrations of nickel sulfate hexahydrate and ethylenediamene are mixed at certain stoichiometric ratios of 0.3‚ 0.4‚ 0.5‚ 0.6‚ 0.7‚ 0.8 and 0.9 to form several complexes. Using

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

Need for Speed: Nascar vs. Formula One. Nascar (National Association for Stock Car Racing) is a world apart from Formula One. Both are exceedingly popular‚ yet they lie at diverse ends of the motor sports spectrum. Most people who have an obsession with cars and racing may know about Nascar and Formula One‚ the two most respected names in motorsports today. At first glance‚ Nascar and Formula One seem very similar; however‚ a closer look reveals

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then
