Calculate the ratio of H+ ions to OH– ions at a pH = 6. Find the concentration of H+ ions to OH– ions listed in Table B of your

Student Guide. Then divide the H+ concentration by the OH– concentration. Record this calculated ratio in Table A of your Student Guide. Compare your approximated and calculated ratios of H+ ions to OH– ions at a pH = 6. Are they the same? Why or why not? Record your explanation in Table A. What is the concentration of H+ ions at a pH = 6? mol/L What is the concentration of OH– ions at a pH = 6? mol/L What is the ratio of H+ ions to OH– ions at a pH = 6? :1

Answer:

You must know the concept of pH of a solution and its relation to the concentration of H+ and OH- ions. pH is a measure of the substance's acidity or basicity. From the definition of Arrhenius, an acid contains an H+ while a base contains a OH- ion. From this definition, we can say that an acidic substance has a higher concentration of H+ ions. Now, I'll introduce here that pH is the value of the negative logarithm of the concentration of H+. In equation,

pH = -log[H+]

The term pOH is therefore also, pOH = -log[OH-]. Therefore, the relationship that connects the two negative logarithms is:

pH + pOH = 14

The pH scale starts from 1 being the most acidic to 14 being the most basic. The neutral pH is 7. Thus, for a pH of 7, the H+ and the OH- concentrations are equal. 

pH = 7 = -log[H+]

[H+] = 1×10⁻⁷ mol/L = [OH-]

Since the concentrations are equal, the ratio is equal to 1.

2 UO2+ + 4 H+U4+ + UO22+ + 2 H2O is second order in UO2+ and third order overall. Complete the rate law for this reaction in the
mr Goodwill [35]

Answer:

r=k[UO_2^+]^2[H^+]

Explanation:

The given reaction is :-

2UO_2^++4H^+\rightarrow U^{4+}+UO_2^{2+}+2H_2O

According to the law of mass action:-

The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.

Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.

The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.  

m = 2 =  is order with respect to UO_2^+

n = order with respect to H+

overall order = m+n = 3

n = 3 - m = 3 - 2 = 1

Rate law is:-

r=k[UO_2^+]^2[H^+]

Given:1 inch = 2.54 cm (exact)1 pound = 454 g1 Liter = 1.0b quarts1 foot = 12 inches1 galion = 4 quarts1 pound = 16 ouncesCalcul
svet-max [94.6K]

We have to convert 0.18 km into feet

First, we need to know the conversions:

1 inch = 2.54 cm (exact)

1 pound = 454 g

1 Liter = 1.0b quarts

1 feet = 12 inches

1 galion = 4 quarts

1 pound = 16 ounces

0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft

Answer: 590 ft (2 significant figures)
