2019-4-27 · On Likert scales, ordinal data and mean values This post has been prompted by an edited collection that I was recently asked to review. Substantive comments on the book will be published elsewhere, so you may want to watch this space for updates; but what I want to do in this post, instead, is share some thoughts regarding research methods and ### Hooke''s Law & the Spring Constant: Definition & …

As an equation, Hooke''s Law can be represented as F = kx, where F is the force we apply, k is the spring constant, and x is the extension of the material (typically in meters). dT = (i)(Kf)(m) is the equation that can be used to model thefreezing point depression. dT represents the change change in temperature. i represents the amount of ions formed from the dissolution ### Relative Strengths of Acids and Bases · Chemistry

2018-8-3 · where the concentrations are those at equilibrium. Although water is a reactant in the reaction, it is the solvent as well, so we do not include [H 2 O] in the equation. The larger the K a of an acid, the larger the concentration of H 3 O +. and A − relative to the concentration of the nonionized acid, HA. Thus a stronger acid has a larger ionization constant than does a weaker acid. dT = (i)(Kf)(m) is the equation that can be used to model thefreezing point depression. dT represents the change change in temperature. i represents the amount of ions formed from the dissolution ### Unifiion of Reaction Metrics for Green Chemistry

First, we construct the appropriate molar ratio, determined from the balanced chemical equation, to calculate the nuer of moles of SO 3 needed. Then using the molar mass of SO 3 as a conversion factor, we determine the mass that this nuer of moles of SO 3 has. The first step reseles the exercises we did in Section 6.4. As usual, we start ### Redox - Wikipedia

2019-4-23 · Adding these two half-cell reactions together gives the balanced equation: 2 KMnO 4 + 3 Na 2 SO 3 + H 2 O → 2 MnO 2 + 3 Na 2 SO 4 + 2 KOH Mnemonics. The key terms involved in redox are often confusing. For example, a reagent that is oxidized loses electrons; however, that reagent is referred to as the reducing agent. ### 8.4: Making Molecules: Mass-to-Mass Conversions

Acids and bases in the Brnsted model therefore exist as conjugate pairs whose formulas are related by the gain or loss of a hydrogen ion. Our use of the syols HA and A-for a conjugate acid-base pair does not mean that all acids are neutral molecules or that all bases are negative ions. It signifies only that the acid contains an H + ion that isn''t present in the conjugate base. ### Chemistry Flashcards | Quizlet

(The subscript nuer, such as the two in O 2 describe how many atoms of an element are in a molecule.) This unbalanced reaction can''t possibly represent a real reaction because it describes a reaction in which one Fe atom magically becomes two Fe atoms.
