Can you please describe each question and why the answer is that 1) What is the strongest metal? 2) The strongest alloy? 3) Which salt has the highest vaporization point? 4) Which covalent molecule has the highest vaporization point? 5) What is the most polar molecule? (It is not HF, Hydrofluoric acid.)
Calculate the pH of a solution made by adding 44 g of sodium acetate, NaCH3COO, to 23 g of acetic acid, CH3COOH, and dissolving in water to make 200. mL of solution
What is the molarity of an aqueous solution containing 21.7 g of glucose (C6H12O6) in 1.2 L of solution?
Nitric oxide, oxygen, and nitrogen react by the following equation. 2 NO(g) N2(g) + O2(g)Kc = 2.3 10^30 at 298 K
An isotonic solution is described as 0.92% NaCl (g/mL). Would this also be the required concentration for isotonic solutions of other salts, such as KCl, MgCl2,
redraw it as a zwiterrion a neutral molecule with a positive and a negative electrical charge (n.b. not dipoles) at different locations within that molecule.
Compute the change in pH when 7.00mL of 0.100 M HCl(aq) is added to 100.0mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq). Compute the change in pH when 7.00mL of 0.100 M NaOH(aq) is added to the original buffer solution.
