What is the discriminant for this equation 4x2-3x-8 equals 0?
The coefficients are a = 4, b = -3, c = -8. The discriminant is calculated with the formula b2 - 4ac, so just replace the coefficients in this formula.
Which do you use to balance equations subscrips or coefficients?
Both. you must have the correct subscripts to represent the correct chemical then you only change the coefficients to balance the equation. The product of a coefficient and a subscript tells how many atoms are present.
How do you factor a polynomial with the equation of 6A2 - B 2?
The given polynomial does not have factors with rational coefficients.
What is the five dollar idea dressed up in fifty dollar name Describe what the equation allows?
Stoichiometry. You can compare the amounts of any materials in the same chemical equation using the formula weights and the coefficients of the materials in the equation.
Which is the correct set of coefficients for the equation below na2cr2o7 plus alpo4 na3po4 plus al2cr2o73?
3, 2, 2, 1
What is a balanced chemical equation . why should chemical be balanced?
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
What do coefficients in a chemical equation represent?
Coefficients in a chemical equation represent the number of units of the formula immediately following the coefficient that are involved in the balanced equation for the reaction.
How are equation coefficients useful in determining amounts of reactions and products?
Equation coefficients show the number of molecules involved in a chemical reaction.
What is the correct set of coefficients for the equation below?
2111.Equation coefficients are needed to write a correct chemical equation
Which coefficients correctly balance the formula equation Nh4 No2 - N2H2O?
The coefficients that correctly balance the equation are: 2NH4NO2 -> N2 + 2H2O
Do you have to choose coefficients that will balance the equation in balancing an equation?
Yes, when balancing a chemical equation, coefficients are adjusted to ensure that the number of each type of atom is the same on both sides of the reaction. This helps maintain the law of conservation of mass.
What coefficients balance the equation Fe O2 Fe2O3?
The balance equation would be 4Fe + 3O2 ==> 2Fe2O3, so the coefficients are 4, 3, 2.
To balance a chemical equation you must adjust the?
coefficients of the reactants and products to ensure the same number of each type of atom on both sides of the equation.
The coefficients from a balanced equation are used to write conversion factors called?
stoichiometric coefficients.
What are the two coefficients?
In a chemical equation, coefficients represent the no. of molecules or atoms involved in a complete chem. reaction.
What is the term for the numbers added in front of some compoundes to balance a chemical equation?
I think moles
When balancing equations should you adjust the subscripts or the coefficients?
Subscripts state how many atoms and Coefficients state how many molecules there are. So when balancing an equation you always adjust the coefficients. When this equation is balanced, what is the coefficient for Ni(NOËÄ)ËÄ? 4
