The ability of orange peels (OP) and almond peels (AP) as adsorbents for the removal of a dyestuff, namely methylene blue (MB) from aqueous solutions has been studied. After their characterization by different techniques (elemental analysis, biochemical analysis, IR spectroscopy, thermogravimetric analysis, scanning electron microscopy, mercury porosimetry), adsorption kinetics of the dye have been investigated using common kinetic models cited in the literature: first order and pseudo-second order. The correlation coefficient has showed that the pseudo-second order kinetic equation best describes the adsorption kinetics for the tested materials. The experimental equilibrium data have been analyzed using linearized forms of Langmuir and Freundlich isotherms. The Langmuir isotherm was found to provide the best theoretical correlation of the experimental data whatever the biosorbents tested. Using the equilibrium coefficients obtained at different temperatures, various thermodynamic parameters such as ΔG°, ΔH°, ΔS° have been calculated. The thermodynamics of MB/OP and MB/AP systems indicated spontaneous and endothermic process.

the singh and robinson families planned a trip to busch gardens. they needed to buy one ticket per person and then pay for parki
hjlf

Let x represent cost of each ticket and y represent cost of parking.

We have been given that the Singh's spent $335 for 5 people and parking. We can represent this information in an equation as:

5x+y=335...(1)

We are also told that the Robinson spent $465 for 7 people and parking. We can represent this information in an equation as:

7x+y=465...(2)

Now we will use elimination method to solve our given system of equations.

Upon subtracting equation (1) from equation (2), we will get:

7x-5x+y-y=465-335

2x=130

\frac{2x}{2}=\frac{130}{2}

x=65

Therefore, the each ticket costs $65.

Upon substituting x=65 in equation (1), we will get:

5(65)+y=335

325+y=335

325-325+y=335-325

y=10

Therefore, the parking costs $10.
