Ireally need ! no one has me! will give brainliest, , andif you are good at science and hurry ! how does the law of conservation of mass apply to this reaction: c2h4 + 3o2 --> 2h2o + 2co2? a. only the oxygen needs to be balanced b. the equation needs to be balanced. there are fewer oxygen atoms in the equation than hydrogen and carbon c. the law of conservation of mass has already been applied d. each element needs to be balanced

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
