Answer:
m AgBr = 1.193 g
Explanation:
- AgNO3 + HBr → AgBr + HNO3
∴ V AgNO3 = 41.8 mL = 0.0418 L
∴ [ AgNO3 ] = 0.152 mol/L
∴ Mw AgBr = 187.77 g/mol
⇒ n AgNO3 = (0.0418 L)(0.152 mol/L) = 6.3536 E-3 mol AgNO3
⇒ n AgBr = (6.3536 E-3 mol AgNO3)(mol AgBr/mol AgNO3) = 6.3536 E-3 mol AgBr
⇒ m AgBr = (6.3536 E-3 mol AgBr)(187.77 g/mol) = 1.193 g AgBr
Answer:
C. Aqueous Solutions
General Formulas and Concepts:
<u>Aqueous Solutions</u>'
- Dissociation
- Solvents and Solutions
Explanation:
Water is the universal solution that solvents are dissolved in. Whenever anything is dissolved in water, it will be an aqueous solution.
Strong ionic solutions dissolve into their ions when dissolved in water.
Weak acids and bases don't fully dissociate in water.
Both the dipole-dipole and hydrogen are essentially same because they result form formation of partial negative and positive charges on the atoms constituting a given molecule. in such molecule, one atom is more electronegative than the other and therefore pulls the shared electrons more to itself than the other atom. the atom that pulls a pair of electrons more to itself becomes partially negatively charged whereas the other atom becomes partially positively charge. the weak negative charges on one molecule attracts weak positive charge on the other molecule creating intermolecular forces referred to as dipole-dipole bonds. Hydrogen bonds form in the same manner they are stronger than typical dipole-dipole bonds. so according to the explanation above D is the correct answer.
