What is the molecular weight of K3[Fe(C2O4)3].3H2O? Use 19K39, 26Fe56, 6C12, 8O16 and 1H1 Select the closest answer

A white precipitate of K2SO4 may be obtained during the identification/test of cobalt ion. This may hinder the true color of the cobalt complex.  Which of the following method is used in the experiment to minimize the interference of K2SO4 in the observation of cobalt complex?

Ba(OH)2 is a strong base and dissociates completely.  If the concentration of Ba(OH)2 is 0.25 M, find the concentration of OH- 

A 200.00 g of city water was evaporated to complete dryness.  Data obtained during this experiment: Weight of the empty beaker: 157.72 g Weight of the beaker with residue (impurities): 160.06 g Calculate the impurities in the city water in PPM Hint: ppm = (weight of the residue in g / weight of the sample ) x 106

Lengths of 5 sticks are 60.0 cm, 47.0 cm, 17.0 cm, 43 cm and 30.0 cm What is the mean length of this sample?

How can you test the solutions given by MATLAB for a non linear system of equations?

Write the MATLAB code line that puts the system of nonlinear equations into a function vector: You do not need to solve, just looking for the function matrix F(x). 

Write a MATLAB function code that intakes 5 values (a, b, c, d, and e) and returns the average of the inputs as “average”. Note, this should require no more than 3 or 4 lines of code (you can omit comments).

You create the below function in MATLAB and try to run it from the Script Editor (by hitting the “Run” button). You get an error message saying “Not enough input values”. What do you need to do to get it to actually run? function z = Lawnmower(x,t)       z=1/2*x^2 – x*t + 1; end

Which of the following is not a native file type in MATLAB?
