Part C: Solution Stoichiometry Answer the following three questions considering the chemical equation presented below:
K2CO3 (aq) + CaCl2 (aq) → CaCO3 (s) + 2 KCl (aq)
1. Calculate the volume (in mL) of 0.0255 M CaCl2 required to react with 28.9 mL of 0.107 M
K2CO3. Show your work for full credit.
2. Calculate the mass of calcium carbonate produced if 15.2 mL of 0.306 M K2CO3 is reacted
with 17.0 mL of 0.295 M CaCl2.
3. Calculate the mass of KCl produced if 12.6 mL of 0.0587 M CaCl2 reacts with excess K2CO3.

It shows that the experiment is designed properly.

Answer; carbon monoxide (co);

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.
