2. [12] When is solid-electrolyte interphase (SEI) formed on anode in Li-ion batteries? Why is it so important?
I have a general question. This relates to Chemistry 121, of the "Introductory Chemistry" book by authors Julia Burdge and Michelle Driessan (2nd Edition) Ch.9. Chapter 9 is on physical properties of solutions. I am having a hard time understanding how to distinguish wether the compound given is a solid, a liquid, a gas or is aqueous. I understand that an electrolyte is an ion that dissolves in water. So, if the compound given is ionic/polar, we can assume it...
A cell Sn/Sn (IV) ion- Ni/Ni (II) ion will have electromotive force. i will post the whole page but the question i need is #4. EXPERIMENT 24 PRE-LABORATORY QUESTIONS Define the following: salt bridge, anode, cathode, electrolytic cell. 1. Using Table 24.1, answer the following questions. (a) Which half-cell will be the anode in a cell composed of Al/APion or Mg/Mg2tion half cell couples. Briefly explain. (b) Sketch a diagram of the cell that would be formed by connecting the...
I need help for this problem ! I have no time plz help me ~ It's from introduction to categorical data analysis chapter 5, exercise 9 5.9 Problem 4.1 with Table 4.8 used a labeling index (LI) to predict r -the probability of remission in cancer patients. a. When the data for the 27 subjects are 14 binomial observations (for the 14 distinct levels of LI), the deviance for this model is 15.7 with df 12. Is it appropriate to...
10) The product formed when an aqueous solution of Cation is added to a soap solution is: a) the Calcium Carboxylate precipitate b) CaCl2(s) c) the solid soap (precipitate). 11) The correct solubilities for the Na+1/K*l metal salts of RCO22, Arso31, and RSO4 +are: (S =soluble, 1 = Insoluble). a) RCO2-2 (S), ArsO3 (S), RSO4+ (S) b) RCO2-2 (S), ArS03-0), RSO41 (1) c) RCO2 2 (), ARSO3-?(), RSO4+ (1) d) RCO2 2 (O), ArS03-(S), RSO4* (S) 12) The correct solubilities...
Please help to answer part a, b , c and d as i have problem understanding mutilpe diode circuit. please give clear explanation on which diode will be assume to be on or off state in the initial state. Find the Q-points (ID , VD) of the diodes in the circuits of Fig. 3. Using the simple model for forward biased diode, the diode voltage is given as 0.75V +15V +10V 15ks2 15k2 D2 D2 Dt 15k2 15k2 10 V...
i have 3 question for solid state physics 1) what is meant when we say a P-N junction is "rectifying"? 2)why is the mobility of an electron greater than the mobility of a hole? 3)why does forward bias in a P-N junction reduce barrier height
I have a problem, and I have the answer but I don't know where the solution comes from. ( I have to be able to solve these myself so please help me by answering the questions about the problem.) If the reactants and products are confined to a volme of 10cm3 what is the pressure of the products (assume ideal gas behavior, complete decomposition of KClO3, and neglect the volume of the solid product, KCl. 2KCLO3(s) ---> 2KCL(s) + 3O2(g)...
So i have the solution for this problem, but my questions is that when they were finding the sound intensity level where did they get the initial intensity? ( 1 × 10−12) A speaker with a power of 58 W is playing music. What is the sound intensity level of the music at a distance of 22 m? Assume that the sound can only be heard in front of the speaker and not behind it. Solution: In order to find...
C program Read file problem: For example, I have an input.txt file like this: q 1 tq 4 p1 10 p2 5 p3 7 p4 20 p5 17 p6 9 p7 3 p8 11 p9 15 p10 1 I want the num of q is in one array, tq is in one array, the order of process(ie,p1,p2) is in one array, and process time is in one array(process time is the number after like p1,p2). There may many q,tq,p so...
