Write the equation for the SECOND neutralization step between H2CO3 and KOH. Please separate each substance...
4 4. a) Parts (a) and (b) below are separate independent problems For each of the following, write a balanced net-ionic equation for the acid-base neutralization reaction that occurs (omitting any spectator ions), and determine the value of the equilibrium constant K for the reaction. Be sure to include phases (such as (aq) or ()) in your reactions. The first one is done for you as an example. (8 pts) Example: Solutions of HBr (ag) and KOH (aq) are mixed...
Please write neatly, thank you. INSTRUCTIONS: I'd recommend answering these on a separate sheet. Make sure to label your answers clearly with each problem number. For each problem, design a synthesis, showing all of the reagents and products along the way. You may use any inorganic reagent and any organic reagent of two carbons or less. ONE STEP SYNTHESIS (20 points]. Choose any FOUR of the five problems below to answer. (Answers beyond the fourth do not count.) 1) 3)...
SHOW YOUR WORK, PLEASE WRITE LEDGIBLY AND CLEARLY 1. Patch clamp recording of a single ion channel yields the following results: Holding Potential Measured Current (mV) 100 50 (pA) 1.0 0.0 +50 +100 +2.0 +3.0 A) Draw a graph of the current (on the vertical axis)-voltage relation for this channel. B) What is the electrical resistance (in ohms) of this channel? (keep in mind mVa 103 volts, pA 101 amperes, and an ohm is a derived unit that is equivalent...

When you write the answers, please write the page number for which the question is located. Thank you! Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
please help with how the flow chart will look like? thank you! Synthesis of n-Butyl Bromide Purpose of the Experiment: In this week's experiment you will be synthesizing n-butylbromide (IUPAC 1-bromobutane from 1-butanol and a concentrated acid via a nucleophilie substitution reaction. It is important to know that alcohols dehydrate to form alkenes in the presence of strong inorganic acids, so care must be taken in this experiment not to heat the reaction too vigorously else an elimination reaction may...
Separating a Mixture, Recrystallization, pre-lab assignment could you also explain why you chose that substance for the empty spaces and question marks EXPERIMENT 4 Pre-Lab Assignment Separating a Mixture, Recrystalliration Name Date 1. Complete the following flowchart which shows how to separate a mixture of sand, sodium chloride and acetanilide. Notice that after a separation process (a down arrow) the filtered solids are shown on the left and the filtrate (the liquid) is shown on the right. The terminal step...
please answer as many questions with detail. 1. Evaluate how much "weight" (mass, strictly speaking) an average human loses daily due to gas exchange while breathing. Find all necessary data, indicate your sources, and present a detailed calculation. 2. 10.00 g of a Mg-Al alloy completely dissolved in hydrochloric acid. The volume of hydrogen gas given off in the chemical reaction is 12.29 L Find the mass composition (in mass %) of the alloy. Assume that the volume of 1...
Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
