Answer:

For, this question,

The balanced equation is; 2Al + 3 ----> 2Al

We can now, calculate how many grams of will be needed to completely convert 15 g of Al into Al.

Here, the reaction produces, 2 moles of Al

So, For 15.0 g of Al; we can calculate;

(15.0 g Al) X (1 mole Al / 26.98 g Al) X (3 moles / 2 moles Al) X (159.81 g / 1 mole )

= 133 g of  will be needed.

Therefore, 133g of will be needed to completely convert 15 g of Al into Al.

Answer:

Zero grams of NaCl & KNO₃  ... The reagents mixed in aqueous solution would not produce products as no driving force is present; i.e., no precipitate, weak electrolyte or gas decomposition product will form.

Explanation:

NaNO₃(aq) + KCl(aq) => (theoritically) NaCl(aq) + KNO₃(aq)

However all chloride salts from metathesis rxns remain soluble and 100% ionized except for halide derivatives of Hg⁺², Ag⁺ & Pb⁺₂.  Further, all NO₃⁻ salt derivatives also remain soluble and 100% ionized.

Technically, metathesis reactions (also known as double replacement rxns) depend upon the formation of a 'driving force' that leaves the reaction system in the form of a precipitate, weak electrolyte (weak acid or weak base) or a gas decomposition product. So, the reaction in this case should be as follows:

NaNO₃(aq) + KCl(aq) => No Reaction

A Venn Diagram is a graphical tool that provides information about the relationship between things.

A Venn Diagram is a graphical illustration using circles to show the relationship between two or more things.

In a Venn Diagram, the items that two things share in common are represented by a region in which the two things intersect.

The items that are exclusive to each thing is shown in regions where the circles are separate.

Thus, a Venn Diagram provides information about the relationship between things.

The similarity is that Elements and Compunds exist in stable form because of the bonds formed between their atoms. The difference is that an element is a material that consists of a single type of atom and a compound consists of two or more types of elements held together by covalent or ionic bonds.

Answer:

Kc = 3.94

Explanation:

CH₃COOH(g) + C₂H₅OH(g) → CH₃COOC₂H₅(g) + H₂O(g)

Liquids aren't included in the equilibrium constant, but at 100°C, all four compounds are a gas.  So the equilibrium equation is:

Kc = [CH₃COOC₂H₅] [H₂O] / ([CH₃COOH] [C₂H₅OH])

Set up an ICE table for each row and calculate the value of Kc.  Then average the results.  (See picture.)

Kc ≈ (3.919 + 4.012 + 3.902) / 3

Kc ≈ 3.94

Using a triple beam balance and a graduated cylinder, a student collected data on a sample of an element:

Mass of sample = 18.9 g

Volume of water = 30.0 mL

Volume of water and sample = 35.0 mL

Calculate the density of the sample using sig figs.

Answer:

3.8 g/mL

Explanation:

Mass of sample = 18.9 g

Volume of water = 30.0 mL

Volume of water and sample = 35.0 mL

Volume of the sample = 35.0 mL – 30.0 mL = 5.0 mL

D = m/v

D = 18.9 g / 5.0 mL =3.8 g/mL

Explanation:

Answer : The concentration of the HCl in original bottle is 0.56 M.

Explanation :

According to neutralization law:

[tex]M_1V_1=M_2V_2[/tex]

where,

[tex]M_1[/tex] = concentration of  HCl

[tex]M_2[/tex] = concentration of NaOH

[tex]V_1[/tex] = volume of HCl

[tex]V_2[/tex] = volume of NaOH

Given:

[tex]M_1[/tex] = ?

[tex]M_2[/tex] = 0.25 M

[tex]V_1[/tex] = 10 mL

[tex]V_2[/tex] = 22.4 mL

Now put all the given values in the above formula, we get:

[tex]M_1\times 10mL=0.25M\times 22.4mL[/tex]

[tex]M_1=0.56M[/tex]

Therefore, the concentration of the HCl in original bottle is 0.56 M.

The enthalpy of solution is the heat evolved or absorbed in solution. From the  calculations performed, the enthalpy of solution is 3.2°C.

The term heat of solution refers to the heat evolved or absorbed when a substance is dissolved in water.

Number of moles of NaNO3 = 6.10 g/85 g/mol = 0.07 moles

Heat absorbed =  20.4 kJ/mol * 0.07 moles = 1.43 kJ

Mass of solution = 1.02 g/mL * 100 mL = 102 g

Mass of system = 102 g +  6.10 g = 108.1 g

Heat capacity of solution = 4.184 J/g･°C

From;

H = mcdT

1.43 * 10^3 J = 108.1 g * 4.184 J/g･°C * dT

dT =  1.43 * 10^3 J/108.1 g * 4.184 J/g･°C

dT = 3.2°C
