Answer:
C
Explanation:
While some dilute acids are said to be weak, some are said to be strong. Now, the principal basis for this classification is based on the extent of ionization in water.
While strong acids ionize completely to give the maximum number of Oxonium ions, weak acids only ionize to an extent and thus do not give the full needed oxonium ions. Hence , we say they gave only a fraction and we term the ionization partial or incomplete.
Asa weak acid, nitrous acid is expected to ionize slightly and not completely. This makes it produce only a fraction of the expected oxonium ions in water
Answer:
135g Na2CO3
Explanation:
I'm going to assume you mean Molality which is mol solute/kg solvent
Molarity would be mol soute/ L solution
we know we have 155g of water which is .155 kg
essentially we have the equation:
mol/kg = 8.20
we substitute .155 in for kg and get:
mol/.155 = 8.20
Solving this gives mol = 1.271
now we must convert to grams using the molar mass
Molar mass Na2CO3 = 106G/mol
so to cancel moles we multiply:
1.271mol x 106g/mol
= 135g
