![]() Hit the ENTER key to get your result of ].Hit MATRIX, scroll to MATH, then 1 to do a determinant.Reactants and products are separated by putting an arrow between them to show the direction of the reaction. Products are listed on the righthand side of the equation. Chemical formulas of reactants are listed on the lefthand side of the equation. Call up Matrix A by typing MATRIX 1 (you should see ) 3 Steps for Balancing Chemical Equations.Once this is done, you can hit "2nd" then "QUIT" to get a blank screen.Enter Matrix B as a 2x1 matrix, using the same technique.Enter Matrix A as a 2x2 matrix, using the technique described above.To calculate c, calculate the determinant of Matrix A.To calculate a and b, multiply the inverse of Matrix A times Matrix B times the determinant of Matrix A: -1 x x det.To obtain the values of a, b, and c, do these steps: We now have two matrices (called Matrix A and Matrix B): The "1a" means that there is one Cr behind the "a" coefficient, zero Cr's behind the "b" coefficent, and 2 Cr's behind the c coefficient. ![]() We are trying to calculate the values of a, b, and c, the coefficients of the reaction. We have two different elements, Cr and O, so we will need two different equations. Now we are ready to talk about balancing equations. Hit the ENTER key, you should see the result "4".Type the blue "2nd" button then "QUIT" (above the MODE button). ![]()
