    1. My 2nd time... Very hard for people with ADHD, and anxiety

      I commend such an effort of publicly displaying language test results (in this instance, the scores for the California Court Interpreter Bilingual Interpreting Exam for Spanish) as a way to encourage oneself and others who see this to keep practicing and improving.

    1. Oxidation Method


    2. Balancing Basic Redox Reactions Balance as if it was acidic, and then add OH- to both sides to neutralize H+ (converting it to H2O) Split Skeletal Eq. into 1/2 Reactions For Each Hal- Reaction Balance all Elements Except O and H Balance O by adding water Balance H by adding H+. Balance Charge by adding e-. Multiply 1/2 rxns by appropriate integer so electrons lost = electrons gained. Add half-reactions, cancelling electrons lost and gained, and check work Add OH- to both sides to neutralize H+ (converting it to H2O) (only the last step is different from balancing acidic reactions)


    3. Balancing Acidic Redox Reactions The following steps allow you to balance a redox reaction and you often do not even have to identify the oxidation state of the various species. Split Skeletal Eq. into 1/2 Reactions For Each Half-Reaction Balance all Elements Except O and H Balance O by adding water Balance H by adding H+. Balance Charge by adding e-. Multiply 1/2 rxns by appropriate integer so electrons lost = electrons gained. Add half-reactions, cancelling electrons lost and gained, and check work

      Know these steps and know how to do the equations

    4. oxidationreduction=loss of electrons=gain of electrons

      Remember where oxidation and reduction occurs

    1. a basic type of chemical reaction involving the transfer of electrons from one atom or chemical entity to another, or more accurately, from one type of orbital to another, that results in new bonds being formed

      Redox reaction definition

    1. Hello! Daisy Thomas is my name. I recently earned an Economics Ph.D. degree from the University of Arizona, Tucson, USA. I earned my CSET AND CBEST (Multiple Subjects) teaching certificates on the side and graduated with a 7.75 GPA! I am an expert in Economics, statistics and Money Market. I worked on this Economics Homework Help and for exam purpose take my economics exam website and my client was so impressed with my work and also gave me 9.2/10 ratings. If you want to me to work for you then you can hire me anytime, I will never disappoint you.

    1. The frequency factor determines the maximum rate of collisions, is a function of particle size, concentration and the rate of diffusion. The steric factor accounts for orientation, in that not all collisions have the correct orientation to result in a reaction, (see video\PageIndex{2}). The rule of thumb is that the more symmetric a molecule the larger the steric factor (a value of 1 means there is no effect, and the pre-exponential is determined by the collision frequency) and the more complicated a molecule, the smaller the steric factor (which is less than one), because only a fraction of the collisions have the correct orientation.

    1. some will evaporate until it reaches its equilibrium

      Equillibrium Vapor Pressure definition - rate of evaporation = rate of condensation.

    2. That is, for molecules of similar mass, the stronger the intermolecular forces the lower the vapor pressure

      The stronger the IM forces. The lower the vapor pressure.

    1. Dr Ellie Murray, ScD. (2022, January 6). School & university administrators, as you grapple with this week’s decisions, spare some time to think about how to delay next January’s start date to Jan 16 2022. Do you need to extend into summer? Change course lengths? Figure it out because this is going to happen again! [Tweet]. @epiellie. https://twitter.com/epiellie/status/1478921243961274370

    1. Note that we obtain the same confidence interval as in Exercise 1. The confidence interval does not depend on the null hypothesis, whereas the significance test does.

      In the video it is said that to obtain the CI, you need to subtract the upper and lower limits from the test value. why do you add it here? which one are you supposed to do and how do you know the difference?

    1. In sum, you can buff your rote memorization by trying to recall frequently, not relying on familiarity, and taking strategic breaks. Trying to solve real problems and trying to accurately recite your understanding of a rule can also be a conduit for remembering. (The ultimate combination? Teaching someone.)

      This is how you study for an exam guys!!!!!!!!!!!!!!!

    1.  Imagine an educational system in which we based our understanding of student potential and achievement upon individual interests and passions, developed and nurtured throughout the years of schooling. This is what most teachers intuitively seek to do. Imagine, then, how amazing schools could be without the false conventions of examinations and tests that are philosophically at variance with all that we know about learning and humanity. Imagine the traditionalist bereft of the Examination Excuse. The fact is, we know that we don’t need examinations for students to get into good colleges and we don’t even need good colleges to learn and be successful, so why is this absurdity still the unchallenged tail that wags the dog of our school systems?
