Enough of a monoprotic acid is dissolved in water to produce a 0.0103 M solution. The pH of the resulting solution is 2.53. Calculate the Ka for the acid.

I got 8.45x10^-4 but it says its wrong.

explain how the Central Bank of Venezuela could adjust its foreign exchange reserves to try to push the black-market bolivar-dollar exchange rate closer to the official fixed exchange rate?

If one were to use a different battery, would the capacitance of a capacitor change?

In python, how do I define a function (check_domain) which takes a email (string) and domain name (string) as input. using slice, it will return true if the email address' domain same matches the input domain name. For example, when input are ”[email protected]” and ”msn.com”, the function you defined should return True. When input are ”[email protected]” and ”hotmail.com”, it should return False

Write method that takes a 2D square array and two integer values that represent the indices of the two columns. Method swaps the first two columns.

int[][] in = {{1,2,3}, {3,2,4}, {4,2,7}};

would output 213234247

public static void swap(int[][] in, int index1, int index2) {

A buffer solution contains 0.14 mol of ascorbic acid (HC₆H₇O₆) and 0.84 mol of sodium ascorbate (NaC₆H₇O₆) in 2.80 L.
The K_a of ascorbic acid (HC₆H₇O₆) is K_a = 8e-05.

pH =  


(b) What is the pH of the buffer after the addition of 0.07 mol of NaOH? (assume no volume change)

pH =  


(c) What is the pH of the original buffer after the addition of 0.21 mol of HI? (assume no volume change)

350 nm of light falls on a single slit of width 0.20 mm. What is the angular width of the central diffraction peak?

In a single slit diffraction experiment, if the width of the slit increases, what happens to the width of the central maximum on a screen?

In a double slit experiment, if the separation between the slits increases, what happens to the distance between the interference fringes?

Which of the following colors produces the widest diffraction pattern

Calculate the pH of a mixture that contains 0.25 M of HCOOH and 0.14 M of HClO. The Ka of HCOOH is 1.8 × 10-4 and the Ka of HClO is 4.0 × 10-8.

(a) A constant force < 31, -13, 36 > N acts through a displacement < 0.17, 0.34, -0.24 > m. How much work does this force do?
Work =           ?J

(b) An object with mass 7 kg moves from a location < 28, 28, -43 > m near the Earth's surface to location < -34, 16, 45 > m. What is the change in the potential energy of the system consisting of the object plus the Earth?
Change of potential energy =     ?J

(c) A spring whose stiffness is 900 N/m has a relaxed length of 0.59. If the length of the spring changes from 0.48 m to 0.86 m, what is the change in the potential energy of the spring?
Change of potential energy =      ?J

(d) You observe someone pulling a block of mass 33 kg across a low-friction surface. While they pull a distance of 6 m in the direction of motion, the speed of the block changes from 3 m/s to 5 m/s. Calculate the magnitude of the force exerted by the person on the block.
F =     ?N

(e) What was the change in internal energy (chemical energy plus thermal energy) of the person pulling the block?
Change in internal energy =     ?J

In August 2018, the U.S. Department of Agriculture (USDA) announced the decision to purchase 11 to 13 million gallons of milk from dairy farmers, amounting to $50 million in total.

With the above information, which do you think was occurring in the dairy market that prompted USDA to make the purchase--a shortage or a surplus? Which person or group of people will USDA's purchase help? And finally do you think the purchase will impact the dairy market in terms of price, supply, and/or demand?

How do you interpret the price indices in Exhibit 3? How do economists construct them? Use Excel regression to analyze the relationship between the adjusted price index (dependent variable and year (independent variable). Interpret your regression findings by discussing the coefficient of determination (R-squared), the regression coefficient, the regression equation, and the p value.   Can you use the regression equation to predict the price indices? Take into account statistical, macroeconomic, and other considerations.
