Limiting reagents Study guides, Revision notes & Summaries

Chapter 2 covers balancing chemical equations, types of chemical reactions such as combination, decomposition, combustion, double replacement reactions (metathesis), and single replacement reactions (oxidation reduction), calculations with moles, finding mass percent, empirical and molecular formulas, and limiting reagents/reactant problems with examples, theoretical and percent yield.

A summary on the topic of amount of substance for A level chemistry (specifically OCR A). Consists of: - explanation of moles and moles equation - step by step calculations of empirical formula, water of crystallisation and identifying limiting reagents - all the equations for this topic with explanations of when to use

Learning Objectives: • Explain the relationship between mass, molecular weight, and numbers of atoms or molecules and perform calculations deriving these quantities from one another • Perform mass-to-mass stoichiometric calculations via conversions to moles • Identify the limiting and excess reagents in a chemical reaction • Calculate the theoretical, actual and percent reaction yield • Define Avogadro’s number and describe the mole quantification of matter Introduction: Did you kno...

Explain the effect of light intensity and temperature on the rate of photosynthesis. - -Light intensity: - Rate will increase until it hits a maximum rate - Will eventually plateau because of other limiting factors - Different wavelengths will have different effects CO2 concentration: - Rate will increase until it hits a maximum rate - Will eventually plateau because of other limiting factors Temperature: - Rate will increase until all reagents are consumed - Enzymes respon...

A peripheral smear with increased polychromasia, schistocytes and spherocytes is indicative of which condition? A. Aplastic anemia B. Iron deficiency anemia C. Hemolytic anemia D. Megaloblastic anemia - correct answer C. Hemolytic anemia Megaloblastic anemia would show larger, less mature RBCs on the smear. Iron deficiency anemia would show hypochromasia, and a lower RBC count. Aplastic anemia would show very little amounts of mature RBCs on the smear Hemolytic anemia results in miss...

HESI A2- Chemistry exam-with 100% verified answers and rationales-2022 1. Which of the following substances allows for the fastest diffusion? A. gas B. solid C. liquid D. plasma Explanation: Diffusion is fastest through gases. The next fastest medium for diffusion is liquid, followed by plasma, and then solids. In chemistry, diffusion is defined as the movement of matter by the random motions of molecules. In a gas or a liquid, the molecules are in perpetual motion. F...
