Convert 0.47g 2-naphthol to mols. mol = g/molar mass. 
Using the coefficients in the balanced equation, convert mols 2-naphthol to mols 2-butoxynaphthalene then you have to Convert mol 2-butoxynaphthalene to grams. g = mols x molar mass. This is the theoretical yield.

The dominant intermolecular force that causes gaseous hcl molecules to attract one another is
AnnyKZ [126]

Answer:

Dipole-dipole attractions

Explanation:

The Cl atom is more electronegative than H, so it attracts the electrons in the H-Cl bond more to itself.

The Cl end of the molecule becomes partially negative (δ-), and the H end becomes more positive (δ+). This separation of charge is called an electric dipole,

When two HCl molecules are near each other, they arrange themselves so that the negative and positive ends of the dipoles line up and attract the two molecules together.

What is the chemical formula for ammonium carbonate?
xenn [34]

(NH4),CO

(NH₄)₂ CO₃  

Explanation:

The chemical formula for ammonium carbonate is (NH4),CO

Ammonium carbonate is made up of:

  Ammonium ion

  Carbonate ion

Ammonium ion is represented by NH₄⁺

Carbonate ion is represented by CO₃²⁻

Now to write the formula, we are going to use their combining powers;

                   

                              NH₄⁺                     CO₃²⁻  

Combining

power                       1                             2

The whiye pigment TiO2 is prepared by the reaction of titanium tetrachloride, TiCl4, with water vapor in the gas phase:
omeli [17]

Answer:

\boxed{\text{62.1 kJ}}

Explanation:

The formula for calculating the enthalpy change of a reaction by using the enthalpies of formation of reactants and products is

\Delta_{\text{r}}H^{\circ} = \sum \Delta_{\text{f}} H^{\circ} (\text{products}) - \sum\Delta_{\text{f}}H^{\circ} (\text{reactants})

                          TiCl₄(g) + 2H₂O(g) ⟶ TiO₂(s) + 4HCl(g)

ΔH°f/kJ·mol⁻¹:    -763.2     -241.828     -939.7    -92.307

\begin{array}{rcl}\Delta_{\text{r}}H^{\circ} & = & [-939.7 + 4(-92.307)] - [-763.2 + 2(-241.828)\\& = & [-939.7 - 369.228] - [-763.2 - 483.656]\\& = & -1308.928 + 1246.856\\& = & \mathbf{-62.1}\\\end{array}\\\text{The amount of heat evolved is } \boxed{\textbf{62.1 kJ}}

Write the answer in scientific notation when you multiply 2 x 104 by 3 x 104.
emmasim [6.3K]

Answer:

6× 10⁸

Explanation:

We need to find the multiplication of 2 x 10⁴ by 3 x 10⁴.

2 x 10⁴ × 3 x 10⁴

= (3 × 2) x 10⁴ x 10⁴

= 6 x 10⁴ x 10⁴

= 6 × 10⁴⁺⁴

= 6× 10⁸

Hence, the required answer is 6× 10⁸.
