Inaccurate Timing Lab Report
The effect of the random errors from this experiment might due to the inaccurate timing as the reflect time to stop the stopwatch when 30cm3 of carbon dioxide is collected in 100mL measuring cylinder is often various from time to time. Time may be longer or shorter than the actual time taken to collect 30cm3 of carbon dioxide. This will then lead to the wrongly calculation of the rate of reaction as the formula of the rate of reaction is:
Rate of reaction=1/(Time taken to collect 30.0cm³ of carbon dioxide (s)) Next, the sources of the random errors in this experiment are the variation in eye level when taking the readings of a measuring cylinder to collect 30cm³of carbon dioxide and the widely spaced graduation mark on a 100mL measuring

Thus, the amount of the carbon dioxide collected in measuring cylinder will be affected, causing the rate of reaction to be altered. In addition, the source of the random errors in this experiment is the widely spaced graduation mark on the 100mL measuring cylinder, result in variation in the eye level to determine the amount of carbon dioxide released and the amount of diluted hydrochloric acid used which may lead to the rate of reaction changes irregularly as the time taken to collect 30cm³ of carbon dioxide is affected.
Equally important, the air movement in the room will also affect the rate of reaction as the air movement will affect the temperature, thus indirectly affect the rate of reaction. When magnesium carbonate reacts with hydrochloric acid, this is an exothermic reaction where heat will be release out and increases the rate of reaction. However, air movement in the room causes the advection of heat. With air movement, the temperature of the reactant mixture and the rate of the reaction are affected. Therefore, the time taken to collect 30cm³ of carbon dioxide is

1764 Words | 8 PagesAnderson and Wood (1925) determined a magnification value equal to 2800 but they neglected the deformation of the tungsten wire under different equilibrium situations. Conversely, the deformation of the wire could be sufficient to reduce the magnification factor of 30%, increasing the moment of inertia. For this reason Uhrhammer and Collins (1990) and Uhrhammer et al. (1996) recomputed the instrument static magnification (GS) that was estimated equal to 2080 ± 60. Using 2800 instead of 2080 in the BB WA simulations leads to a magnitude error of +0.129 (e.g. Uhrhammer et al., 2011).

574 Words | 3 PagesExperiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

603 Words | 3 PagesSuppose we have a single-hop RCS where there is one AF relay that amplifies the signal received from a transmitter and forwards it to a receiver. Assume that the transmitter sends over the transmitter-to-relay channel a data symbol ${s_k}$, from a set of finite modulation alphabet, $S={S_1, S_2,ldots,S_{cal A}}$, where ${cal A}$ denotes the size of the modulation alphabet. The discrete-time baseband equivalent signal received by the relay, $z_k$, at time $k$ is given by egin{equation} z_k = h_{1,k}s_k + n_{1,k},~~~~for~~k=1,2,ldots,M label{relaySignal} end{equation} where $n_{1,k}sim {cal N}_c(0,sigma_{n1}^2)$ is a circularly-symmetric complex Gaussian noise added by the transmitter-to-relay channel, $h_{1,k}$ denotes the transmitter-to-relay channel, and

How Does The Amount Of Baking Soda Mixed With Vinegar Affect The Volume Of Gas Produced?
1211 Words | 5 PagesHow does the amount of baking soda mixed with vinegar affect the volume of gas produced per 10 seconds? A reaction is when (usually) a solute acts on a solvent to create a reaction. An example of a reaction is an explosion, Here we will be using baking soda and vinegar which are our two components which will cause for a reaction to take place. Reactions can be affected by several things such as temperature, concentration and the presence or absence of a catalyst which is a substance which can increase the rate of reaction.

Reaction Between Hydrochloric Acid And Calcium Carbonate
1398 Words | 6 PagesAIM To design an investigation to study the kinetics of a reaction of your choice RESEARCH QUESTION With respect to hydrochloric acid (HCl), what is the order of reaction in the reaction between HCl and calcium carbonate (CaCO3) determined by changing the concentration of HCl and measuring the volume of carbon dioxide gas (CO2) collected in 30 seconds whilst keeping the mass of the powdered CaCO3 constant and the temperature of the reaction system at 25oC? BACKGROUND INFORMATION Calcium carbonate (CaCO3) is a chemical compound that is commonly found in rocks such as chalk, limestone, marble and travertine in all parts of the world. It also used as a form of medicine as a dietary supplement for a person with insufficient calcium intake because calcium is needed by the body for healthy bones, muscles, nervous system, and heart. CaCO3 is also used as an antacid to relieve
