Answer:
The answer to your question is: They are stronger than those in water.
Explanation:
When a substance is heated, heat is breaking forces among molecules like hydrogen bonds, london forces, van der waals forces, etc, if a substance has a lot of these forces, the boiling point will be higher because more forces must be broken.Then, glycerol must have stronger forces than those of water.
Answer:
a. 10.54
Explanation:
reaction is
NH₃ + NaOH -----------------NH₄Cl + H₂O
0.10 mol NaOH will consume 0.10 mol NH₃ thereby decreasing the initial amount of moles NH₃ and increasing that of NH₄Cl
mol NH₃ = 0.80 - 010 = .70
mol NH₄Cl = 0.80 + .10 = 0.90
pH = pKₐ + log (( NH₃/NH₄Cl))
pH = 9.26 + log (( 0.90 + 0.70)) = 9.26 + 0.11 = 10.54
Answer:
Osmosis is a type of passive transport. The best statement that accurately describes osmosis is: Osmosis is the diffusion of water across a membrane.
Explanation:
Answer:
Electrolysis is the passage of a direct electric current through an <em><u>ionic</u></em> substance that is either molten or dissolved in a suitable solvent. This results in chemical reactions at the electrodes and the separation of materials.
