Answer:

(a) fractional distillation

(b) the column consists of a distilling flask, a fractionating column, a thermometer, a bunsen burner, and a beaker to collect the distilled liquid. it is used to separate liquid with close boiling points also, the fractionating has glass beads and a large surface area for condensation and vaporization of liquid

Explanation:

fractional distillation is used to separate liquids with close boiling points

For a hypothetical reaction the linear Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45. What is the activation
Y_Kistochka [10]

Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45. What is the activation energy for this reaction is described below.

Explanation:

When the rates are equal and the concentration of reactants and products are constant not equal. Other like activation energies and potential energies are not necessary for equilibrium.

The activation energies of the forward and reverse reactions ,the rates of the forward and reverse reactions are  25 minutes ago.

For a hypothetical reaction the linear Arrhenius equation is LaTeX: y=-15035x+41.45y = − 15035 x + 41.45

15kj/mol is the answer..

Write balanced chemical equations for the complete neutralization reactions that take place when the following acids are titrate
swat32

Answer:

(a) NaOH_{(aq)} + HCl_{(aq)} --> NaCl_{(aq)} + H_2O_{(l)}

(b) NaOH_{(aq)} + CH_3COOH_{(aq)} --> CH_3COONa_{(aq)} + H_2O_{(l)}

(c) H_3PO_4_{(aq)} + 3NaOH_{(aq)} --> 3H_2O{(l)} + Na_3PO_4_{(aq)}

Explanation:

For a reaction involving sodium hydroxide and hydrochloric acid, the balanced equation of reaction is:

NaOH_{(aq)} + HCl_{(aq)} --> NaCl_{(aq)} + H_2O_{(l)}

For a reaction involving sodium hydroxide and acetic acid, the balanced equation of reaction is:

NaOH_{(aq)} + CH_3COOH_{(aq)} --> CH_3COONa_{(aq)} + H_2O_{(l)}

For a reaction involving sodium hydroxide and phosphoric acid, the balanced equation of reaction is:

H_3PO_4_{(aq)} + 3NaOH_{(aq)} --> 3H_2O{(l)} + Na_3PO_4_{(aq)}

One mole of silver has a mass of 107.9 grams. Approximately how many atoms of silver are present in one mole of silver?
irga5000 [103]

Answer:

The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.

Option C is correct.

Explanation:

Step 1: Data given

Mass of 1 mole silver = 107.9 grams

Step 2: Calculate the number of atoms in 1 mole of silver

To calculate the number of atoms in 1 mole, we multiply the number of Avogadro by the number of moles

Number of atoms = 1 mol * 6.022 *10^23 atoms/ mol

Number of atoms = 6.022 * 10^23 atoms

Since the number of Avogadro says there are 6.022 * 10^23 atoms per 1 mole. The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.

Option C is correct.
