How does the method for solving equations with fractional or decimal coefficients and constants compare with the method for solving equations with integer coefficients and constants?
The method is the same.
What are the common characteristic between simultaneous linear equations in 2 unknowns which have no solutions?
The coefficients and constant in one of the equations are a multiple of the corresponding coefficients and constant in the other equation.
What makes a system of equations dependent?
If one (or more) of the equations can be expressed as a linear combination of the others. This is equivalent to the statements the matrix of coefficients does not have an inverse (or is singular), or the determinant of the matrix of coefficients is zero.
Solve linear equations with complex coefficients on both sides?
You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.
What are some complex equations for 17?
Complex equations? Do you mean complicated equations whose solution is 17, - or equations with complex (non-real) coefficients or solutions? If you can explain, please resubmit your question.
What in chemical equations provide mole ratios that can be used as conversion factors?
Coefficients
How are coefficients used in writing chemical equations?
They indicate the number of molecules in a substance.
What is used to balance chemicals equations?
coefficients
Are Chemical equations are balanced by changing the subscripts of the molecules?
ABSOLUTELY NOT Change the coefficients on reactant or productt units.
How Chemical equations are balanced by changing the subscripts of the molecule true or false?
False. They are balanced by changing the coefficients.
Why are coefficient used to balance equations?
Coefficients are used to balance equations because if you change the subscript, than you would change the substance.
How are coefficients used to balance chemical equations?
In a chemical equation, the coefficients tell you how much you need of each molecule or atom, to balance the equation.
Is this true or false Subscripts can be changed in order to balance a chemical equation?
False. Subscript cannot be change to balance chemical equations. Only coefficients can be added to balance chemical equation.
How does the method for solving equations with fractional or decimal coefficients and constants compare with the method for solving equations with integer coefficients and constants?
The method is the same.
Does a chemical formula describes a chemical reaction?
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
Why must chemical equations be balanced using coefficients?
The number of atoms in the reactant and products must be equal to obey the law of conservation of mass.
How do you tell how many atoms of iron and oxygen are present as products and how many are present as reactants in the chemical equations?
The number of atoms is indicated by coefficients.
