Absorbance of the sample solution is 0.152AU. The three main uncertainty sources of absorbance in photometric analysis are repeatability, drift of the photometer and uncertainty due to possible interfering effects. The respective uncertainty components were estimated by the analyst as follows: Repeatability standard deviation is 0.005AU, uncertainty due to possible drift is ± 0.001AU and uncertainty due to the possible interfering effects is ± 2% of the absorbance value.
Please calculate the combined standard uncertainty of absorbance. Please provide 4 decimal places after the decimal point.

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
