Chemical equations provide a written representation of a chemical reaction by showing the relationship between reactants and products. While they do not have a physical structure like molecules, they are structured to follow the law of conservation of mass and allow scientists to understand the stoichiometry of a reaction.

Scientists typically represent a dominant allele with a capital letter, such as "A." This helps differentiate it from a recessive allele, which is usually represented by a lowercase letter, such as "a."

How do scientists usually communicate and defend the results of an investigation

density changes when the substance changes.

The unit for density is kg m-3.

The set of points the graphed equations have in common. This is usually a single point but the lines can be coincident in which case the solution is a line or they can be parallel in which case there are no solutions to represent.

They are used to represent known and unknown values in equations. Usually x, y, and z are unknown; and a, b, and c are known. But u can use anything to represent anything! It helps to solve for unknowns that you need to figure out!

No, linear equations don't have x2. Equation with x and y are usually linear equations. Equations with either x2 or y2 (but never both) are usually quadratic equations.

Scientists use uppercase letters to represent dominant genes and lowercase letters to represent recessive genes. For example, "R" might represent a dominant gene for round seeds, while "r" might represent a recessive gene for wrinkled seeds.

In scientific equations, lambda often represents wavelength, a measure of the distance between two consecutive points in a wave. It is commonly used in physics, particularly in fields like optics, acoustics, and quantum mechanics.

Delta as a mathematical symbol usually means "change". It's usually used the same way in physics and chemistry, though it's sometimes used in chemical equations to represent heat.

Chemical equations provide specific information about the reactants and products involved in a chemical reaction, including the ratio of the substances involved and the energy changes that occur. This level of detail is not conveyed in word equations, making chemical equations more precise and useful for scientific analysis. Additionally, chemical equations can be used to predict the outcome of reactions and to balance equations, which is important for accurate experimental design.

Usually not.

The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.

It is essentially a list of equations that have common unknown variables in all of them. For example, a+b-c=3 4a+b+c=1 a-2b-7c=-2 would be a system of equations. If there are the same number of equations and variables you can usually, but not always, find the solutions. Since there are 3 equations and 3 variables (a, b, and c) in this example one can usually find the value of those three variables.
