Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation

Thus I assumed an asymptote at 23°C. 1st equation: An equation for an exponentially decaying graph is in the form of: y = a + b (e –m x) Where: a= Vertical Translations (Ambient Temperature)‚ b= Dilations‚ m= Gradient x= Time (t)‚ y= Temperature (T (t)) From the data‚ we know that the value of ‘a’ is always equal to 23 °C. The original equation is equal to: T (t) = 23 + b (e –m t) This part of the investigation had some issues. I had formed the equation but was confused on how to solve it. Later

combusts as: CH4(g) + O2(g) ---> CO2(g) + 2 H2O(g) Net Ionic Equations Net ionic equations are equations that show only the soluble‚ strong electrolytes reacting (these are represented as ions) and omit the spectator ions‚ which go through the reaction unchanged. When you encounter net ionic equations on the test‚ you’ll need to remember the following solubility rules‚ so memorize them! Also keep in mind that net ionic equations‚ which are the bare bones of the chemical reaction‚ usually take

certain run from the previous task was twice duplicated to for a “hot and cold” test for reaction rate. The prior run was again duplicated for a test with catalyst. The data obtained was graphed in a linear regression form‚ using the Arrhenius equation: lnk=-EaR-1T+lnA‚ reaction rate: rate = k[A]x[B]y and other principles held in chemistry. The graph from the results determined that there is a relation between rate and the previously mentioned factors. The results validated the notion that temperature

inflexion point. 2. People use differential equations to predict the spread of diseases through a population. Populations usually grow in an exponential fashion at first: However‚ populations do not continue to grow forever‚ because food‚ water and other resources get used up over time. Differential equations are used to predict populations of people‚ animals‚ bacteria and viruses that are being affected by external events. The logistic equation (developed in the mid-19th century) allows for

Figure 1 below shows the change in magnitude of the steady state acceleration with time. This graph complies with Newton’s second law as the force applied is equal to 1 and the mass remains constant so and an acceleration of one is expected. I also tested this by changing the value of the force applied‚ to a value of 2‚ which in theory should give and equivalent change in the acceleration‚ to a value of 2. From Newton’s second law: it can be seen that as the force varies‚ provided moment of inertia
