Answer: The categories of intermolecular forces in the molecules above are dispersion forces, dipole forces, hydrogen bonding.
Explanation:
Here are the different kinds of intermolecular forces present in the above;
Ethane - C2H6 has London dispersion forces—it’s a nonpolar covalent compound— and no other intermolecular attractions.
Dimethyl ether - CH₃OCH₃ has London dispersion force, dipole-dipole attraction, and hydrogen bonding
Ethanot- C2H5OH has has London dispersion force, dipole-dipole attraction, and hydrogen bonding
Answer:
1.46 moles NaCl
Explanation:
To find the moles of NaCl, you need to multiply the given value (0.731 moles BaCl₂) by the mole-to-mole ratio of the two relevant molecules. This ratio is made up of the coefficients in the balanced reaction. The numerator should contain moles NaCl to allow for the cancellation of moles BaCl₂. The final answer should have 3 sig figs to reflect the given value.
1 BaCl₂(aq) + Na₂SO₄(aq) ---> BaSO₄(s) + 2 NaCl(aq)
0.731 mole BaCl₂ 2 moles NaCl
--------------------------- x ------------------------- = 1.46 moles NaCl
1 mole BaCl₂
