Chemistry: Identifying Chemical Reactions Name_____________________________________________________ Date___________________________ Your text book identifies four different types of chemical reactions (section 16-4). Other sources identify as many as six types of chemical reactions. For now we will stick with the scheme used by your book. The four types of chemical reactions shown in your book are: a) Synthesis b) Decomposition c) Single displacement or Single replacement d) Double displacement or Single replacement e) Combustion Write balanced equations for each of the word equations below, then indicate which kind of reaction it is 1. Sodium bromide + Calcium hydroxide
Double displacement reaction: Chemical reactions in which one component each of both the reacting molecules is exchanged to form the products. 3. What does the stoichiometry of a chemical reaction mean? Why is it important? Stoichiometry is a section of chemistry that involves using the relationships between reactants or products in a chemical reaction to determine the desired quantitive data.
(2 points) Mg(s) + 2 HCl(aq) → H2(g) + MgCl2(aq) 2. Determine the partial pressure of the hydrogen gas collected in the gas collection tube. (3 points) partial pressure H2 = total pressure - vapor pressure of water = 746mmHg - 19.8mmHg = 726mmHg 3. Calculate the moles of hydrogen gas collected. (4 points) n = 125 4.
Record your hypothesis on page 123. -My hypothesis is we can determine the different between each chemical reaction by the temperature change.To descide which one is exothermic and endothermic. 4. Summarize the procedures you will follow to test your hypothesis. -We measured in each chemical and added water besides, HCl we added NaOH.
b. Calculate the fuel value in kJ/g for each of these compounds. c. FOr each hydrocarbon determine the percentage of hydrogen by mass. d. By comparing your answers for part (b) and (c), propose a relationship between hydrogen content and fuel value in hydrocarbons. a) for a we first need to find a balanced equation for when the hydrocarbons combust to form CO2 and H20.
To perform this experiment, we will utilize emission spectra, titrations, and thermal gravimetric analysis, using knowledge from Experiments 10, 4, Titrations of Na2CO3 and NAHCO3 by HCl (hydrochloric acid) will be performed to determine the concentration of HCl, as well as the number of moles of HCl present within the sample of baking soda. As a result, we will be able to determine the molar concentration of HCl by determining its equivalence point (the point on the graph where the exact amount of rectant needed to perform a reaction has been added) from graphical analysis. Na2CO3(aq.) + HCl(aq.) ==> NaHCO3(aq.)
This was the solution that was used in order to obtain the absorption spectrum for each of the different iron (II) ligand examples different flasks. Each of the five flasks were
