What type(s) of intermolecular forces are expected between ch3ch2ch2ch2oh molecules?
12345 [234]

Answer : Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

Explanation :

The given molecule is CH_3CH_2CH_2CH_2OH.

Three types of inter-molecular forces are present in this molecule which are Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.

  • Hydrogen-bonding : when the partial positive end of hydrogen is bonded with the partial negative end of another molecule like, oxygen, nitrogen, etc.
  • Dipole-dipole attraction : When the partial positively charged part of the molecule is interact with the partial negatively charged part of the molecule. For example : In case of HCl.
  • London-dispersion force : This force is present in all type of molecule whether it is a polar or non-polar, ionic or covalent. For example : In case of Br-Br , F-F, etc

Hydrogen-bonding is present between the oxygen and hydrogen molecule.

Dipole-dipole forces is present between the carbon and oxygen molecule.

London-dispersion forces is present between the carbon and carbon molecule.

Copper (II) oxide can be heated until it decomposes into elemental copper and oxygen gas. Is 0.695 grams of Copper (II) oxide is
insens350 [35]

Answer:

0.55 g of Cu can produced by this decomposition

Explanation:

Let's think the reaction of decomposition:

2CuO → 2Cu + O₂

Ratio is 2:2. 2 moles of CuO can decompose into 2 moles of Cu and 1 mol of oxygen.

Let's convert the mass of oxyde to moles → 0.695 g. 1 mol/ 79.55 g =

8.74×10⁻³ moles

8.74×10⁻³ mol of CuO decompose to 8.74×10⁻³ moles of Cu

Let's find out the mass → 8.74×10⁻³ mol . 63.55 g/1mol = 0.55 g

Enter the net ionic equation representing aqueous acetic acid neutralized by aqueous barium hydroxide.
IrinaK [193]

Answer:

The answer to your question is below

Explanation:

Data

Aqueous acetic acid

Aqueous barium hydroxide

Formula

Acetic acid    CH₃CH₂COOH

Barium hydroxide   Ba(OH)₂

Neutralization reaction

        CH₃CH₂COOH    +    Ba(OH)₂      ⇒  Ba( CH₃CH₂COO)₂ + H₂O

                                                                    Barium acetate + H₂O

Barium acetate =  Ba( CH₃CH₂COO)₂ = Ba(C₃H₅O₂)₂
