For this assignment you will be comparing acids and bases. In the photo is shows what you have to do

I submitted the last question too early so please don't charge me as this is the question. Please charge us for this one.  We think the answer to number 12 is the hydronium ion.  Please see our work and let us know your thoughts.  This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl

All changes saved 14. Answer the question below. Use the rubric in the materials for help if needed. Acids and bases have very different properties. Explain how you would identify a substance that you encounter every day based on the typical properties of acids and bases. Use details to support your answer.

Third Slide: Slide Titled Strong Acids. Chart with 3 columns. First Column is name of acid, Second Column is formula of acid, Third Column is use of acid. You only need to list 1 use. The acid names for your chart: Sulfuric acid, Nitric acid, Chloric acid, Perchloric acid, Hydrochloric acid, Hydroioidic acid and Hydrobromic acid. Research the internet for a use.

Can you please help me thankyou

Try Again Your answer is incorrect. • H3 PO4: Your answer for the major species present when dissolved in water is incorrect. • HF: Your answer for the major species present when dissolved in water is incorrect. The chemical formulae of some acids are listed in the first column of the table below, and in the second column it says whether each acid is strong or weak. Complete the table. List the chemical formula of each species present at concentrations greater than about 10-6 mol/L when about a tenth of a mole of the acid is dissolved in a liter of water. acid H₂PO4 ΗΝΟ, HIO, HF strong or weak? weak weak strong weak species present at 10-6 mol/L or greater when dissolved in water 2- H₂, PO, H₂, PO, HPO¾¯‚H₂0¹ 3⁹ 4' 4 + HNO₂, NO₂, H₂O + 103, H₂0* HFF,H₂0¹ X 1,0,... 5

QUESTION 2 What is the pH of a solution with OH- of 0.0001 M KOH at 25°C. Give the answer in 2 significant figures. State whether the solution is an acid, base, or neutral. QUESTION 3 Fruit, milk, and wheat are examples of: O a. Nucleic Acids O b. Lipids O c. Carbohydrate O d. Proteins

Learning Goal: To calculate pH and use it as a measure of acidity. Part A 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 [H3O+] =2×10-14 M? pH = -log[H3O+] Express the pH numerically using one decimal place. [H3O+] = 10-PH As pH decreases, acidity increases. As pH increases, acidity decreases. • View Available Hint(s) Πν ΑΣφ Acidic solution: pH 7 pH = Submit
