Chemistry- Acids, Bases, And Buffers Written Exam 2024. Define Acid - correct answer A proton donor. Define Base - correct answer A proton acceptor. Why is H+ a Proton - correct answer Because hydrogen is just one proton and one electron. Take away the electron and you're left with H+. Define Alkali - correct answer A type of base which dissolves in water to form OH- ions (a soluble base). What is a Monobasic Acid and Give an Example of One - correct answer A monobasic acid e.g. ...

6. (TCO 6) A gas at a temperature of 95 degrees C occupies a volume of 165 mL. Assuming constant pressure, determine the volume at 25 degrees C. Show your work. (Points : 5) Using Charles’ Law, (V1/T1) = (V2/T2). First, convert temperature to KELVIN (T1 = t1 +273) Thus, T1 = 95 + 273 = 368. We have V1 (165 mL) & T2 = (25 + 273) = 298. V2 = (V1*T2)/T1 = (165 mL*298)/368 = 133.6 mL. 0 Short 16 7. (TCO 6) A sample of helium gas occupies 1021 mL at 719 mmHg. For a gas sample at constant...

(b, 5 pts) What volume, in Liters, of a 0.2 M H3PO4 solution can be prepared by diluting 50 mL of a 5M H3PO4 solution? Show your work. (Pts. : 10) 2. Question: (TCO 7) (a, 5 pts) What is the mass/volume percent of a solution prepared by dissolving 43 g of NaOH in enough water to make a final volume of 120 ...

Chapter 6: Calculate the molar Mass the following 1. CH4 C = 1 x 12g/mol = 12 g/mol H = 4 x 1 g/mol = 4 g/mol CH4 = 16 g/mol 2. H2O H = 2 x 1 g/mol = 2 g/mol O = 1 x 16 g/mol = 16 g/mol H2O = 18 g/mol 3. MgBr2 Mg = 1 x 24 g/mol = 24 g/mol Br = 2 x 80 g/mol = 160 g/mol MgBr2 = 184 g/mol 4. H3PO4 H = 3 x 1 g/mol = 3 g/mol P = 1 x 31 g/mol = 31 g/mol O = 4 x 16 g/mol = 64 g /mol H3PO4 = 98 g/mol 5. Ca(OH)2 Ca = 1 x 40 g/mol = 40 g/mol O = 2 x 16 g/mol = 32 g...
