The atom is sometimes said to be similar to a miniature planetary system, with electrons orbiting the nucleus. What does the uncertainty principle have to say about this view of the atom?

Answers

Answer 1

Answer:

The uncertainty principle says this view is only a guess, a snapshot of what the electrons around the nucleus could possibly look like. Specifically, the uncertainty principle says that we cannot know the exact location and speed of the electrons. Therefore, the planetary-like arrangement of the electrons around the nucleus is rarely ever assumed.

Aqueous sulfuric acid (H2SO4) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium sulfate (Na2SO4) and liquid water (H2O). Suppose 5.88g of sulfuric acid is mixed with 6.3 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 3 significant digits

Answers

Answer:

2.16 g H₂O

Explanation:

Since we are not given the limiting reagent, we need to convert both reactants into the product. The actual amount of product will be the smaller mass produced.

To find the answer, we need to (1) convert grams reactant to moles reactant (via molar mass), then (2) convert moles reactant to moles H₂O (via mole-to-mole ratio from balanced equation coefficients), and then (3) convert moles H₂O to grams H₂O (via molar mass). It is important to arrange the ratios in a way that allows for the cancellation of units.

The balanced equation:

1 H₂SO₄(aq) + 2 NaOH(s) -----> 1 Na₂SO₄(aq) + 2 H₂O(l)

Molar Mass (H₂SO₄): 2(1.008 g/mol) + 32.065 g/mol + 4(15.998 g/mol)

Molar Mass (H₂SO₄): 98.073 g/mol

Molar Mass (NaOH): 22.990 g/mol + 15.998 g/mol + 1.008 g/mol

Molar Mass (NaOH): 39.996 g/mol

Molar Mass (H₂O): 2(1.008 g/mol) + 15.998 g/mol

Molar Mass (H₂O): 18.014 g/mol

5.88 g H₂SO₄           1 mole              2 moles H₂O            18.014 g
----------------------  x  -----------------  x  ------------------------  x  -----------------  =  
                                98.073 g            1 mole H₂SO₄           1 mole

=  2.16 g H₂O

6.3 g NaOH            1 mole              2 moles H₂O              18.014 g
--------------------  x  -----------------  x  --------------------------  x  ----------------  =
                              39.996 g           2 moles NaOH            1 mole

=  2.84 g H₂O

Since H₂SO₄ produces the smallest amount of product, it is the limiting reagent. In this case, H₂SO₄ is completely used up before NaOH has the chance to react totally. Therefore, the actual amount of H₂O produced is 2.16 g.

Round your answer to two decimal places.

Answers

1.2 x 10² L of oxygen is formed if 77.37 L of water is produced.

The density of water at STP = 0.99 g/ ml but we will assume 1 g/ml

Determine the mass of water ([tex]H_{2}[/tex]o) = 77.37 L × [tex]\frac{1000 ml}{1l}[/tex] × [tex]\frac{1g}{ml}[/tex]

The mass of water = 77370 g

Convert mass into moles = 77370 [tex]H_{2}[/tex]o × [tex]\frac{1mol}{18.01528} H _{2}O[/tex]

= 4294.6876 mol of [tex]H_{2} O[/tex]

Use stoichiometry to find how many mols of oxygen [tex]o_{2}[/tex] were used:

= 4294.6876 mol of [tex]H_{2} O[/tex] × [tex]\frac{13 mol }{10 mol}[/tex]

= 5583.0939 mol [tex]o_{2}[/tex]

Convert mols to mass = 5583.0939 mol ×[tex]\frac{32 g}{mol }[/tex]

= 178659.0059 g [tex]o_{2}[/tex]

Convert mass into liters

The density of [tex]o_{2}[/tex] at STP = [tex]\frac{1.439}{ml}[/tex]

Density of [tex]o_{2}[/tex] = 1.2 × [tex]10^{2}[/tex]

Yoghurt is a colloid because it contains living bacterial cultures, proteins, lipids, and milk solids in addition to water. A colloid forms a homogenous mixture rather than settling or separating over time because the particles or components are uniformly distributed throughout the medium. A water-in-oil emulsion, specifically yoghurt is regarded as an emulsion colloid. This implies that water droplets are evenly distributed across an ongoing fat or oil matrix.

Answers

The pH of the solution is obtained to be 9.67.

What is a buffer?

A buffer is a solution that serves to militate against changes in acidity or alkalinity. The buffer is often made of a solution of a strong acid and its salt or a weak base and its salt.

Now we have the that;

Number of moles of base = 250 /1000 *  0.80 = 0.2 moles

Number of moles of salt = 150/1000 *  0.50 = 0.075 moles

Total volume of the solution = 250 + 150 = 400 mL or 0.4 L

Molarity of the base = 0.2 moles/0.4 L = 0.5 M

Molarity of the salt =  0.075 moles/ 0.4 L = 0.1875 M

pKb = - log( 1.8 x 10^-5) = 4.74

pOH = pKb + log [salt/base]

pOH =  4.74 + log (0.1875/ 0.5)

Degrees Brix is the sugar content of an aqueous solution. One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution a as percentage by mass.

Mass percent refers to the percentage of solute present in the solution.

The concentration of the substance can be expressed in mass percent.

we have to first calculate mass percent.

So, we can write,

Mass percent = mass of solute / mass of solution x 100.

Mass of solution = mass of solute + solvent.

Here, sucrose is the solute and the water is the solvent.

The mass of the solute is 1.5Kg and the mass of the solvent is 1Kg.

Mass of solution = 1.5 + 1 = 2.5 Kg.

Mass percent = 1.5/2.5x100

Mass percent is 60%.

The concentration of an HCl acid solution is initially 6mol/L. What would the concentration of a new solution be if 200 mL of the original HCl solution is diluted with 1L of water.

Answers

Taking into account the definition of dilution, the concentration of the new solution is 1 mol/L.

Dilution

When it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.

Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volume

Final volume

In this case, you know:

Ci= 6 mol/LVi= 200 mLCf= ?Vf= 1 L (1000 mL) water + 200 mL of HCL= 1200 mL

Replacing in the definition of dilution:

6 mol/L× 200 mL= Cf× 1200 mL

Solving:

(6 mol/L× 200 mL)÷ 1200 mL= Cf

1 mol/L= Cf

In summary, the concentration of the new solution is 1 mol/L.

1 mole of H2O2 reacts with 2 moles of permanganate

 9 * 10^-3 moles of H2O2 reacts with  9 * 10^-3 moles * 2 moles/1 mole  

= 1.8 * 10^-2 moles

Hence, permanganate is the limiting reactant

b) The theoretical yield of oxygen is;

2 moles of oxygen produced 3 moles of O2

9 * 10^-3 moles oxygen  produced 9 * 10^-3 moles *  3 moles/2 moles

= 0.0135 moles

If 1 mole of O2 occupies 22.4 L

0.0135 moles of O2 occupies 0.0135 moles * 22.4 L/ 1 mole

= 0.302 L or 302 mL

c) Percentage yield of oxygen = 178 mL/ 302 mL * 100/1

= 60%

How many grams of Aspirin (acetylsalicylic acid) should we form in this reaction if we started with 2.08g of Salicyclic Acid?

Answers

Taking into account the reaction stoichiometry, 2.713 grams of aspirin are formed when 2.08 grams of salicyclic acid reacts.

Reaction stoichiometry

In first place, the balanced reaction is:

C₄H₆O₃ + C₇H₆O₃ (Salicyclic Acid) →C₉H₈O₄ (aspirin) + C₂H₄O₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

C₄H₆O₃: 1 moleC₇H₆O₃: 1 moleC₉H₈O₄: 1 moleC₂H₄O₂: 1 mole

The molar mass of the compounds is:

C₄H₆O₃: 102 g/moleC₇H₆O₃: 138 g/moleC₉H₈O₄: 180 g/moleC₂H₄O₂: 60 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

C₄H₆O₃: 1 mole ×102 g/mole= 102 gramsC₇H₆O₃: 1 mole ×138 g/mole= 138 gramsC₉H₈O₄: 1 mole ×180 g/mole= 180 gramsC₂H₄O₂: 1  mole ×60 g/mole= 60 grams

Mass of aspirin formed

The following rule of three can be applied: if by reaction stoichiometry 138 grams of salicyclic acid form 180 grams of aspirin, 2.08 grams of salicyclic acid form how much mass of aspirin?

[tex]mass of aspirin=\frac{2.08 grams of salicyclic acidx 180 grams of aspirin}{138 grams of salicyclic acid}[/tex]

mass of aspirin= 2.713 grams

Then, 2.713 grams of aspirin are formed when 2.08 grams of salicyclic acid reacts.
