Solution chalk 0.1 m hcl water final concentration time (sec.) a 0.1g 5 ml 5 ml | 0.05 m b 0.1g 4 ml 6 ml | c 0.1g 3 ml 7 ml d 0.1g 2 ml 8 ml e 0.1g 1 ml 9 ml a. calculate the solution concentration for each of the hcl samples. the first one has been done for you. b. as the concentration of the hcl solution increased, did the speed of the reaction increase or decrease? c. therefore, as the concentration of a reactant increases, does the rate of the reaction increase or decrease? d. do your predictions previous to this investigation agree with your results? e. make a general rule about the effects of the concentration of reactants on reaction rates.

About 8 gallons of fuel will be used. (8.08)

The answer is c) pyrite

I'm sorry but i'm only grade

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.
