13. Nitric acid, HNO3, is a strong acid in aqueous solutions. It is sold commercially as a concentrated solution with a density of 2.14 kg.L-¹ and containing 58% mass of HNO3. We introduce 10.0 mL of this solution in a 250.00 mL volumetric flask which is then filled to the mark with distilled water. This solution is called S. S is then diluted 100 times to afford solution S'. a. What is the definition of a strong acid? | b. What is the concentration of solution S"? c. What is the pH of solution S'?

An explosive whose chemical formula is C;H,N6O6 produces water, carbon dioxide, and nitrogen gas when detonated in oxygen. Write the chemical equation for the detonation reaction of this explosive. 4. A number of compounds are used in cement, and reactions among them occur when water is added. In one, CaO reacts with Al2O3 and water to form Ca3Al2(OH)12. Write a balanced chemical equation for this process. 5. Ethanol, C2H5OH, is found in gasoline blends used in many parts of North America. Write a balanced chemical equation for the combustion of C2H5OH to form CO2 and H2O. 6. Balance the following equations. a. reaction to produce "superphosphate" fertilizer: Ca3(PO4)2(s)+H2SO:(aq)→Ca(H,PO4)2(aq)+CaSO4(s) b.…

Be sure to answer all parts. Nitroglycerin (C;H;N3O9) is a powerful explosive. Its decomposition may be represented by 4C H;N3O9 6N2 + 12CO, +10H,0 02 This reaction generates a large amount of heat and gaseous products. It is the sudden formation of these gases, together with their rapid expansion, that produces the explosion. (a) What is the maximum amount of O, in grams that can be obtained from 8.00 x 10 g of nitroglycerin? (b) Calculate the percent vield in this reaction if the amount of O, generated is found to be 26.3 g. 0/0
