What is Venn Diagram?

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 enthalpy of solution (∆H) of NaNO₃ is 20.4 kJ/mol. If 6.10 g NaNO₃ is dissolved in enough water to make a 100.0 mL solution, what is the change in temperature (°C) of the solution? (The specific heat capacity of the solution is 4.184 J/g・°C and the density of the solution is 1.02 g/mL)

Answers

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

What is is heat of solution?

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

Using a triple beam balance and a graduated cylinder, a student collected data on a sample of an element:Mass of sample = 18.9 gVolume of water = 30.0 mLVolume of water and sample = 35.0 mL..... using SigFig Rules *

Answers

The question is incomplete; the complete question is;

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

Data for CH3COOH(l) + C2H5OH(l) CH3COOC2H5(l) + H2O(l) balance were obtained at 100. The initial concentrations of the reagents are indicated in columns 1 and 2 of the table below and the CH3COOC2H5 concentrations in equilibrium are given in column 3. Calculate H2O and determine the value of KC

Answers

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

A researcher takes a 10 mL sample of HCl from a bottle and titrates it with NaOH. It was found that 22.4 mL of 0.25 M NaOH were required to reach the equivalence point. What is the concentration of the HCl in original bottle?

Answers

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.

how many grams of Br2 are needed to completely convert 15.0g Al to Albr3?

Answers

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.
