Ensure they satisfy the original equation.Types of EquationsEquations can be classified into various types based on their structure, degree, and the nature of their variables. Here are some key types of equations:Linear Equations: These are equations of the form ax + b = 0 where a and b are constants, and x is a variable. They graph as straight lines and have a degree of one.Quadratic Equations: These equations are of the form ax² + bx + c = 0 where a, b, and c are constants, and x is a variable. They graph as parabolas and have a degree of two.Polynomial Equations: These have the general form aⁿxⁿ + aⁿ⁻¹xⁿ⁻¹ + ... + a¹x + a⁰ = 0 where n is the degree of the polynomial, and each term includes a constant coefficient a and a power of x.Exponential Equations: In these equations, the variable appears as an exponent, such as in aˣ bˣ = c. Solving these often involves logarithmic functions.Logarithmic Equations: These involve logarithmic functions, such as log_b(x) = y, and can be rewritten into exponential form for easier manipulation.Rational Equations: These include rational expressions, such as fractions with polynomials in the numerator and denominator. An example is (x+1)/(x-1) = 3.Trigonometric Equations: These involve trigonometric functions like sine, cosine, or tangent, such as sin(x) = 0.5. Solutions often require knowledge of inverse trigonometric functions or identities.Differential Equations: These involve derivatives, such as dy/dx = 3x. They describe the relationship between a function and its rate of change,

Learning ObjectivesBy the end of this lesson, students will be able to identify and write balanced chemical equations, differentiate between different types of reactions, and interpret molecular models and reaction mechanisms to predict the outcomes of chemical processes. Students will also learn to write word equations, convert them into skeleton and balanced chemical equations, and understand the significance of ionic and net ionic equations. Additionally, students will gain the skills to classify reactions into synthesis, decomposition, single replacement, double replacement, and combustion reactions, and use molecular models to visualize chemical changes at the molecular level.Introduction Understanding how to represent chemical reactions is fundamental in AP Chemistry. These representations, including word equations, skeleton equations, balanced equations, ionic equations, and net ionic equations, provide a structured way to describe how reactants transform into products. Additionally, recognizing different reaction types and utilizing molecular models and reaction mechanisms helps in visualizing and predicting the outcomes of chemical processes.Types of Chemical Equations1. Word EquationsWord equations describe the reactants and products of a chemical reaction using their names. They are the simplest form of chemical equations and provide a straightforward description of the substances involved. Example: In this reaction, methane and oxygen react to form carbon dioxide and water.2. Skeleton EquationsSkeleton equations use chemical formulas to represent the reactants and products but do not indicate the relative amounts of each. This form is an intermediate step before balancing the equation. Example: Here, CH₄​ represents methane, O₂​ represents oxygen, CO₂​ represents carbon dioxide, and H₂O represents water.3. Balanced Chemical EquationsBalanced chemical equations ensure that the number of atoms for each element is the same on both sides of the equation, reflecting the Law of Conservation of Mass. This step is essential for accurately representing the reaction. Example: In this balanced equation, there are 4 hydrogen atoms and 2 oxygen atoms on both sides, ensuring mass conservation.4. Ionic EquationsIonic equations show the species that are actually present in the reaction mixture, including dissociated ions. This form is particularly useful for reactions occurring in aqueous solutions where ionic compounds dissociate into their constituent ions. Example: This equation shows sodium chloride and silver nitrate dissociating into their ions in aqueous solution, forming solid silver chloride and aqueous sodium nitrate.5. Net Ionic EquationsNet ionic equations show only the species that undergo a change during the reaction, omitting spectator ions that do not participate in the actual chemical change. This provides a

Unduly influenced by any overrepresented subpopulations. This is a much larger population than the samples used to develop other popular BMR equations using height, weight, and age, such as the Harris-Benedict equation (239 subjects), the revised Harris-Benedict equation (337 subjects), and the Mifflin-St Jeor equations (498 subjects).Since the Oxford/Henry equations were developed, a meta study found that the Oxford/Henry equations had the best combination of low error (small average deviations between measured and predicted BMRs) and low bias (not systematically over- or under-estimating BMR in particularly large or particularly small people) across both sexes. Similarly, another huge study with nearly 17,000 subjects found that the Oxford/Henry equations were among the best-performing equations for people in all BMI categories. Finally, a 2022 meta-analysis found that the FAO/WHO/UNU equations performed best in people with overweight and obesity, but that review included relatively few studies that used the Oxford/Henry equations. However, BMR estimates provided by the FAO/WHO/UNU equations and the Oxford/Henry equations tend to converge at higher body weights and BMIs (in other words, if the FAO/WHO/UNU equations perform well in people with obesity, the Oxford/Henry equations do too).Overall, in most populations, the Oxford/Henry equations are the best BMR equations based on height, weight, age, and sex.Cunningham, 1991Much like the Oxford/Henry equations, the 1991 version of the Cunningham equation is the result of synthesizing data from multiple other studies. Cunningham had first developed an equation for estimating BMR from fat-free mass in 1980. In the intervening decade, more research groups investigated the relationship between fat-free mass (FFM) and BMR, allowing Cunningham to systematically analyze the results from a total population of 1482 subjects. The studies included both males and females, with a pretty even mix of lean and obese subjects.Subsequent research has supported the validity of the 1991 Cunningham equations. For instance, a decade after Cunningham’s study, Wang and colleagues analyzed the FFM/BMR relationship in the published research (which included another seven studies that came out after Cunningham’s equation was published). It was a somewhat less rigorous analysis – I don’t believe they applied weightings based on the number of subjects in each study – but it found that the “average” equation to predict BMR from FFM was BMR = 21.5 * FFM + 407, which is practically indistinguishable from Cunningham’s equation.Furthermore, they modeled the theoretical relationship between FFM and BMR that was revealed from animal research spanning a range of 7 orders.
