Acid rain contains sulfuric acid (H2SO4), to answer the above question you need to predict the chemical reactions that occur, and the products of those reactions in each case. 1. Determine if the chemicals involved are acids, bases, or essentially neutral. 2. Write the chemical equation for the reaction between acid rain and granite (SiO2). 3. Write the chemical equation for the reaction between acid rain and calcium carbonate/limestone (CaCO3) 4. Using the information from the chemical reactions you wrote, describe why lakes with granite beds are more susceptible to acid rain than lakes with limestone beds.

If a sample of a certain solution is determined to have a pH of 3.7, what is the concentration of [H3O+] in the solution? Submit your answer in scientific notation and round off the significand (first number) of your answer to two decimal places. Answer x10 moles/liter Keypad Keyboard Shortcuts

please help! Formic acid (Ka = 1.8 x 10-4) is used as a preservative on hay and animal feed. Hypobromous acid (Ka = 2.0 x 10-9) is used as a germicidal agent for pools and spas. An agricultural chemist wishes to test whether a mixture of the two would be more effective in preventing hay decay over the winter months. Calculate the pH of a solution that is 0.050 M in hypobromous acid and 0.025 M in formic acid.

1. (1 point) The [H+] of coffee is about 1 x 10. Its pH is 2. (1 point) The [OH-] of baking soda is about 1 x 10. Its pH is 9. The [H+] is 3. (4 points) Balance these equations by putting the number coefficients to the left of each product or reactant. If no number is needed (coefficient = 1), then leave that space blank. Al + O2 → Al2O3 а. NażCO3 + HCI → NaCl + CO2 + H20 C3H8 + O2 → CO2 + H2O с. d. CSH12 + O2 → CO2 + H2O 4.

Using the constant below, calculate the molar concentration (M) of acid H3O* in solution if the concentration of OH- is 3.4 x 10-5. Kw = 1.0 × 10-14 M²= [H3O*][OH]. %3D O a) 2.9 x 10-10 O b) 2.0 x 10-10 O) 3,4 x 109 d) 2.4 x 10-10 e) 3.4 x 109

Make the following conversions. In each case, tell whether the solution is acidic or basic. pH [H30*] [OH"] acidic or basic? 1.00 M M acidic M 2.3 x 104 M basic 2.5 x 10-2 M M acidic 5.25 M acidic 00

What is the ratio of bicarbonate ion to carbonic acid ([HCO−3]/[H2CO3])([HCO3−]/[H2CO3]) in blood serum that has a pHpH of 7.40?  Express your answer using three significant figures.

Which of the following statements is TRUE? Select one: A solution with a pOH of 4 is basic.   It is not possible to have a pH outside the range 0 - 14.   A 1 M solution of HCl will have a higher pH than a 1 M solution of HF. Carbonic acid (Ka = 4.3 × 10-7) is a stronger acid than oxalic acid (Ka = 5.9 × 10-2). Basic solutions don't contain any H3O+ ions.

I Review | Constants | Periodic Table Learning Goal: Part A To calculate pH and use it as a measure of acidity. The pH expresses the molar concentration of hydronium ions in an aqueous solution on a logarithmic scale: What is the pH of an aqueous solution with [H30+] =2x10-14 M? Express the pH numerically using one decimal place. pH = -log[H3O+] • View Available Hint(s) [H3O+] = 10-pH As pH decreases, acidity increases. As pH increases, acidity decreases. • Acidic solution: pH 7 pH = Submit Part B Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. What is the molar concentration of H3O+ in a cola that has a pH of 3.120? Express your answer with the appropriate units. • View Available Hint(s) [H3O*] = Value Units Submit
