Haylee Clifton May 16, 2017 Sheehan P. 2 Concentration of acid Carbon goes from fossil fuels into the atmosphere when the fuels are burned the carbon dioxide goes from the atmosphere then dissolves into the surface of the ocean. Reduces seawater PH, carbonate ion concentration and saturation states of biologically important calcium carbonate minerals. What does different concentrations of acid do to shells? If the acid concentration is high, the mass will decrease. The shell lab the students escort an experimental design to see if the acid concentration is high, will the density decrease? To start the experiment you need, 3 plastic cups 7 oz,
Repeat for each trial. Rinse volumetric pipette with vinegar and drain into the waste beaker. Weigh and record the mass of each 200mL beaker. Add 10.00mL of vinegar into each beaker and weigh them and record their again. Add 50mL of de-ionized water to the beakers and place them under the drop counter on top of a stir plate, submerging the pH meter into the solution. Place the stir bar into the beaker and carefully turn on the stir plate so that the stir bar spins without splashing or hitting the sides of the beaker or the pH
Fossil fuels, such as coal and oil, are Carbon rich compounds, the combustion of which produces Carbon Dioxide, a pollutant and a greenhouse gas. A large amount of energy is released during this process, which is why the pollutants off products are tolerated. This process occurs constantly throughout the world, in power stations, vehicles and cooking ovens, leading to an immense volume of CO2 being released every second, 50% of which is absorbed by oceans (Oce...
The reaction will take place in the conical flask from where the gas produced will travel into the up-turned measuring cylinder. The gas will then displace the water in the tube. I will measure out exactly 50ml of 1molar hydrochloric acid into the conical flask. I will then weigh out exactly or as close as possible to 2 grams of small sized marble chips.

Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
The objective of this lab experiment was to determine the density of a set of plastic beads by using two different methods and decide which method was better. Density is a physical property that is defined as the ratio of an object’s mass to an object’s volume. Also, density can be described as the measurement of how compact a substance is in a given space. To find an object’s density, it is necessary to measure the object’s mass, the amount of matter present, and volume, the space it takes up. Also when studying density, it is key to note how objects with varying densities behave. The density of water, at room temperature, is 1.00 g/mL and is often used to determine the density of a substance based on if it sinks or floats in water. The measurement
The ocean has always absorbed CO2 from the air. An article presented in Nature August 2012 enlightens that about half of all CO2 generated by human is absorbed by the ocean. This chemical reaction is occurring naturally and the rate at which carbon is being absorbed, the concentration of carbonic acid is increasing. This has overwhelming concerns, particularly for shelled creatures. Animals such as corals, crabs, and calms need calcium carbonate to build their shells. Calcium Carbonate is dissolved by carbonic acid and consequently these animals are incapable of maintaining casings of calcium. Bio geosciences in 2010, suggested that carbon confiscation by oceans and land is lessening, which has the potential to further worsen the impact of carbon emissions.
Also the investigation will be performed in a sensible manner and there is no dangerous behaviour. Prediction When the experiment is taking place I believe that the magnesium in the hydrochloric acid will begin to bubble and then disappear, I also
The Effect of Concentration of Acid on the Rate of Reaction With Calcium Carbonate Calcium + Hydrochloric ð Calcium + Carbon + Water Carbonate Acid Chloride Dioxide CaCO3 (s) + 2HCl (aq) ð CaCl2 (aq) + CO2 (g) + H2O (l) Introduction I will be using the reaction between calcium carbonate and hydrochloric acid to see how the concentration of acid affects the rate of a reaction. By doing the above experiment I will prove that the higher the concentration of acid, the faster a reaction will occur. I have carried out a previous experiment called the 'Disappearing Cross', in which I used the reaction between thiosulphate, hydrochloric acid and water to see how concentration affects the rate of reaction. When we added the hydrochloric acid to the water and thiosulphate a reaction occurred, causing the water to become foggy so that the cross was no longer visible through the conical flask. The results for the Disappearing Cross experiment were as follows; Volume of Thiosulphate (Cm3) Volume of Water (Cm3) Volume of HCl (Cm3) Concentration (%) Time taken for X to disappear (seconds) 5 25 5 17 711 10 20 5 33 286 15 15 5 50 185 20 10 5 67 113 25 5 5 83 82 You can see that when the hydrochloric acid was most dilute the cross took 711 seconds to disappear, and when the acid was most concentrated the cross took just 82 seconds to disappear.
The purpose was to crest five separate layers of colored sugar water. The concept of the lab is to find the density of the colored sugar water by dividing mass over volume. Mass is a measure of the amount of matter in an object. Volume is the quantity of 3 dimensional space occupied by a liquid, solid or gas. Density is the measurement of an object's mass per unit of volume. The lab was setup to study the concept on how to calculate the density by mass divided by volume. The independent variable is the mass of the sugar. The dependent variable is the density of the sugar H2O. The constant variable is the volume of the H2O.
Carbon dioxide or CO2 is known to be one of a number of gases that are astonishingly transparent to the visible light that falls on the Earth from the Sun, but it absorb the infra-red radiation that emitted by the warm surface of our Earth, to prevents its loss into space. Moreover, CO2 has varied considerably and this affected the Earth’s temperature. Most common source of this CO2 is known as the fossil fuel. Fossil fuels are primarily coal, hydrocarbons, natural gas, or fuel oil that formed from the remains of the dead plants and also animals. The burning fossil fuel that has been created by humans is the largest source of emissions of the carbon dioxide.
The Solubility Pump works because of the fact that CO2 is more than twice as soluble in cold water than warm water. This allows carbon to be removed from the atmosphere at the poles, and then pumped into the deep ocean that contains this similar cold, high-density water. The Biological Pump is driven by the biota in the oceans. When CO2 is absorbed from the atmosphere into the oceans it is converted into Dissolved Inorganic Carbon (DIC). At the ocean’s surface, the primary production of marine phytoplankton then converts this DIC into organic material. Certain phytoplankton also have the ability to combine dissolved calcium with dissolved carbonate to create Calcium Carbonate (CaCO3). This calcium carbonate is used to make up the hard shell coatings of many marine organisms from small plankton such as coccolithophores and phytoplankton, to larger organisms such as mollusks, crustaceans, and echinoderms. The biological pump can mostly be explained as the cycling of these organisms and their shells. When an organisms dies, the fixed carbon from its soft or hard tissue is mostly contained in the upper lev...
