    Chemistry Aim: I am trying to find out whether the equation 2CuCO3 ® Cu2O + 2CO2 + ½O2 or the equation CuCO3 ® CuO + CO2 is correct for the decomposition of copper carbonate. Introduction: This is my background research, this information may help me when I am trying to see which equation is correct. I have used the book Chemistry 1 by OCR as my reference. Relative Atomic Mass: This is the mass of an atom of the element

  • Determining The Chemical Formula For A Hydrated Compound Containing Copper, Chloride, And Water Molecules

    903 Words  | 4 Pages

    Introduction: This experiment is based on determining the chemical formula for a hydrated compound containing copper, chloride, and water molecules in the crystal structure of the solid compound, using law of definite proportion. The general formula of the compound is CuxCly•zH2O, and aim is to determine chemical formula of this compound. Law of definite proportion, sometimes called Proust’s law, states that a compound always has exactly the same proportion of elements by mass. This

  • Factors That Affect A Continuous Variable Of A Type II Error?

    1199 Words  | 5 Pages

    Often times as researchers, we will take continuous variables and break it up into categories, typically for the purpose of grouping, or to measure an outcome measure. We usually decide on a reasonable cut-point and place the data in the appropriate category. Streiner (2002) asserts that this categorization results in lost information, reduced power of statistical tests, as well as an increased probability of a Type II error. In Streiner (2002) article, written primarily for researchers, he states

    Sensitivity Analysis-Colectomy, CABG, and PCI Multiple analyses were conducted to test the sensitivity of price regression results: 1) HHI measurement by different definitions and levels; 2) GLM regression using different distribution families; and 3) non-linearity of age, HHI, and HMO penetration. HHI Measured by Admissions vs Inpatient Days The main GLM regression models included a hospital admission HHI where the total number of admissions in a hospital is measured as a proxy of the hospital’s

    More mean, and less standard deviation indicate more important factors (Rahman, 2014) relating to the propensity to save. On the basis of the table no.2, it is clear that ‘to have enough social security” is the most important factor to the propensity to save (Mean 3.78, and SD 0.91). Then takes place for ‘children education’ (Mean 3.72, and SD 1.15), and ‘to get good interest’ (3.71, and 0.81). To be rich man is in the 4th place for cause of human saving. Reliability and Validity Test: The right

    while maintaining the output current ripple within a pre-defined range. To study the impact of VSFPWM on switching loss reduction over the entire modulation index range, the simulations were carried out different speeds (modulation indices) for a constant load torque. Table II and Table III compares the current ripple, and the percentage change in the current distortion and the switching losses for CSFSVPWM-VSFSVPWM and CSFDPWM2-VSFDPWM2 techniques respectively. Similar to the analytical results at

  • How Did Amedeo Avogadro Contribute To Law

    761 Words  | 4 Pages

    Respect that is given to someone who is admired. Respect that you earn from doing or achieving something great. Amedeo Avogadro was an Italian scientist who formulated what is now known as Avogadro's law. Hailed as a founder of the atomic-molecular theory, he was the first scientist to realize that elements could exist in the form of molecules rather than as individual atoms. His biggest contribution to science however, the Avogadro's law states that equal volumes of gases under the same conditions
