Answers

Answer:

I think B) electronegativity is the correct answer.

Electronegativity is the property which is  used to determine the degree of polarity between two bonded atoms. Therefore, the correct option is option B.

What is polarity?

Polarity is the dispersion of electrical charge over the atoms linked by a chemical bond. Bonds between identical atoms, such as H2, are electrically homogeneous in the sense that both hydrogen atoms are electrically neutral, but bonds between different atoms are electrically inequivalent.

Electronegativity is the property which is  used to determine the degree of polarity between two bonded atoms. The relative electronegativities of the elements determine the polarity of a bond. Electronegativity is the ability of an element's atom to attract electrons to itself when it is part of a compound.

How many liters of 0.200 M sodium hydroxide do you need to titrate 0.300 L of a 0.100 M diprotic acid to the equivalence point?

Answers

The volume of the sodium hydroxide solution needed for the reaction is 0.3 L

We'll begin by writing the balanced equation for the reaction.

H₂X + 2NaOH → 2H₂O + Na₂X

From the balanced equation above, the following data were obtained:

The mole ratio of the acid, H₂X (nA) = 1The mole ratio of base, NaOH (nB) = 2

From the question given above, the following data were obtained:

Molarity of base, NaOH (Mb) = 0.2 M. Volume of acid, H₂X (Va) = 0.3 L. Molarity of acid, H₂X (Ma) = 0.1 M. Volume of base, NaOH (Vb) =?

MaVa / MbVb = nA / nB

(0.1 × 0.3) / (0.2 × Vb) = 1/2

0.03 / (0.2 × Vb) = 1/2

Cross multiply

0.03 × 2 = 0.2 × Vb

0.06 = 0.2 × Vb

Divide both side by 0.2

Vb = 0.06 / 0.2

Vb = 0.3 L

What is the volume of HCl (r= 1.17 g / cm ^ 3, omega = 36 \%) required to precipitate silver in the form of AgCl from 2, 000 g of an alloy containing 22% by weight of Ag, if used 1.5 times the amount of precipitating reagent?​

Answers

The volume of precipitating reagent, HCl required to precipitate silver in the form of AgCl from 2,000 g of an alloy containing 22% by weight of Ag is 0.530 L

In order to determine the volume of precipitating reagent, HCl required to precipitate silver in the form of AgCl from 2,000 g of an alloy containing 22% by weight of Ag, the following steps are followed:

Step 1.

The concentration of the HCl solution is calculated using the formula:

Molarity = percentage * specific gravity * 1000 cm³ / molar mass * 1 L

Percentage purity of HCl = 36% = 0.36

specific gravity, r = 1.17 g/cm³

molar mass of HCl = 36.5 g/mol

Concentration of HCl = 0.36 * 1.17 * 1000 / 36.5 * 1

Concentration of HCl = 11.53 mol/L

Therefore, 1 L of HCl solution contains 11.53 moles of HCl

Step 2:

The equation of the dissociation of HCl solution is given below:

HCl (aq) ------> H⁺ (aq) + Cl⁻ (aq)

1 mole of HCl produces 1 mole of Chloride ions, Cl⁻

Equation of reaction between Silver in the alloy and HCl is given as follows:

Ag (s) + H⁺Cl⁺ (aq) -----> AgCl (s)

A white precipitate of AgCl is formed but hydrogen gas is not formed as Silver is a less reactive metal.

1 mole of HCl produces 1 mole of Cl⁻ which reacts with 1 mole of Ag to produce 1 mole of AgCl precipitate.

Step 3: Determine the mass and number of moles of silver in the alloy

Percentage of silver in the alloy = 22% = 0.22

Mass of silver in 2000 g alloy = 0.22 * 2000 g

Mass of silver in 2000 g alloy = 440 g

Number of moles of silver in 440 g of silver is determined using the formula below:

number of moles = mass / molar mass

molar mass of silver = 108 g/mol

number of moles of silver = 440 /108

number of moles of silver in the alloy = 4.074 moles

Step 4: Calculate the volume of HCl required

Since 1 mole of Cl⁻ ions react with 1 mole of Ag; 4.074 moles of Cl⁻ ions will be required to react with 4.074 moles of Ag.

1 L of HCl solution contains 11.53 moles of Cl⁻

Volume of HCl solution that contains 4.074 moles of Cl⁻ = 4.074 * 1L/11.53

Volume of HCl that contains 4.074 moles of Cl⁻ = 0.353 L

Since 1.5 times the amount of precipitating reagent HCl is required, volume of HCl required = 1.5 * 0.353 L

Volume of precipitating reagent HCl required = 0.530 L

Therefore, the volume of precipitating reagent, HCl required to precipitate silver in the form of AgCl from 2,000 g of an alloy containing 22% by weight of Ag is 0.530 L

Funnel
Evaporating dish
Beaker or graduated cylinder
Tripod
Bunsen burner
Filtration
If the rock salt is one large chunk, grind it into a powder using a mortar and pestle or a coffee grinder.
Add 30-50 milliliters of water to six heaping spatula scoops of rock salt.
Stir to dissolve the salt.
Place the filter paper in the mouth of the funnel.
Place the evaporating dish under the funnel to collect the liquid.
Slowly pour the rock salt solution into the funnel. Make sure you don't over-fill the funnel. You don't want the liquid to flow around the top of the filter paper because then it isn't getting filtered.

What is the pressure of a 1.0 L flask containing 0.12 g of He at 25°C? (R= 0.0821 L atm/mol K)

Answers

Answer:

The pressure of the flask is 0.73 atm.

Explanation:

To solve this question, we should use the ideal gas law: PV=nRT, where P represents the pressure (in atm in this case), V represents the volume (in L), n represents the number of moles of gas, R is the ideal gas constant, and T represents the temperature (in K).

Before we can plug our values into the equation, we must convert so that our units cancel out. First, we should convert our temperature from degrees Celsius to degrees K.

25°C + 273.15 = 298.15K

Next, we should convert the 0.12 g He to moles using the molar mass of He.

0.12 g He * (1 mole He/4.003 g He) = 0.029978 mol He

Now, we can plug in the values into the equation and solve for the pressure.

PV = nRT

P = (nRT)/V

P = (0.029978 mol He * 0.0821 L*atm/mol*K * 298.15 K)/(1.0 L)

P = 0.73 atm

Therefore, the correct answer is 0.73 atm.

Determine the volume (L) of nitrogen monoxide gas that is created at STP when 32.2 g

of solid copper reacts with excess nitric acid.

3Cu(s) + 8HNO3(aq) — 3Cu(NO3)2 (aq) + 4H2O(1) + 2NO(g)

Answers

Taking into account the reaction stoichiometry and STP conditions, the volume of nitrogen monoxide gas that is created at STP when 32.2 g of solid copper reacts with excess nitric acid is 7.5677 L.

Reaction stoichiometry

The balanced reaction is:

3 Cu(s) + 8 HNO₃(aq) → 3 Cu(NO₃)₂ (aq) + 4 H₂O(l) + 2 NO(g)

By reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:

Cu: 3 molesHNO₃: 8 molesCu(NO₃)₂: 3 molesH₂O: 4 moles NO: 2 moles

The molar mass of the compounds is:

Cu: 63.54 g/moleHNO₃: 63 g/moleCu(NO₃)₂: 187.54 g/moleH₂O: 18 g/moleNO: 30 g/mole

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

Cu: 3 moles× 63.54 g/mole= 190.62 gramsHNO₃: 8 moles× 63 g/mole= 504 gramsCu(NO₃)₂: 3 moles ×187.54 g/mole= 562.62 gramsH₂O: 4 moles ×18 g/mole= 72 gramsNO: 2 moles ×30 g/mole= 60 grams

STP conditions

The STP conditions refer to the standard temperature and pressure, which values are 0 °C and 1 atmosphere and are reference values for gases. In these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Moles of NO formed

The following rule of three can be applied: if by reaction stoichiometry 190.62 grams of Cu form 2 moles of NO, 32.2 grams of Cu form how many moles of NO?

moles of NO= (32.2 grams of Cu× 2 moles of NO)÷ 190.62 grams of Cu

moles of NO= 0.3378 moles

Then, 0.3378 moles of NO are formed.

Volume of NO created

Now, you can apply the following rule of three: if by definition of STP conditions 1 mole of NO occupies a volume of 22.4 liters, 0.3378 moles occupies how much volume?

volume= (0.3378 moles× 22.4 L)÷ 1 mole

volume= 7.5677 L

Finally, the volume of NO created is 7.5677 L.

What are the gas laws? (Include Boyle's law, charles's law, gay lussac's law, an avogadro's law) Could someone please summarize these for me ples? Brainliest answer also yes

Answers

Answer:

Boyle's Law: When the pressure of a gas increases, the volume of the gas will decrease as long as the temperature and amount of gas are constant.

So basically pressure is inversely proportional to Volume, when one increases, the other decreases, vice versa.

Equation: [tex]P_{1} V_{1} = P_{2} V_{2}[/tex]

Charles Law: When the temperature of a gas increases, the volume of a gas will also increase if the pressure and amount of gas are constant.

So basically Temperature and volume are directly proportional.

Equation: [tex]\frac{V_{1}}{T_{1}} = \frac{V_{2} }{T_{2} }[/tex]

Gay Lussac's Law: When the temperature of a gas increases, the pressure of a gas also increases when volume and the amount of gas remain constant.

Basically, Temperature and Pressure are directly proportional.

Equation: [tex]\frac{P_{1}}{T_{1}} = \frac{P_{2} }{T_{2} }[/tex]

Avogadro's Law: The most intuitive gas law. When you increase the amount of gas, the volume will also increase.

Meaning the moles (amount of gas) is directly proportional to volume.

Equation: [tex]\frac{V_{1} }{n_{1} } = \frac{V_{2} }{n_{2} }[/tex] (n stands for moles)

There is a combined gas law and ideal gas law but those are just the gas laws mentioned above but combined together. These should be everything.

Answer:

Boyle Law is when pressure and volume have a reverse relationship when temperature is the same.Charles law is basically when volume and temperature have a relationship when the pressure is the same.Lussac Law is I think just when I pressure and temperature is directly tied together when the volume stays the same.I dont think there is any "avogadro law", there is only pressure volume and temperature.

B. Subatomic particles don’t follow the same laws of physics as large objects.

C. The force of gravity acts more strongly on subatomic particles than on large objects.

D. It is easier to measure the movement of subatomic particles than the movement of large objects.

Answers

The characteristics of the subatomic particles allow to find which is the correct answer:

B)  Subatomic particles don’t follow the same laws of physics as large objects.

Subatomic particles are the contributors to atoms, the main three being electrons, protons, and neutrons. The movement of these particles is described by the Schrodinger equation, the result of which is wave function.

To obtain the physical function of the wave mergers, the probability function must be constructed.

                        P = Ф* Ф

therefore the movement of the subatomic particulars is probabilistic at all times, when a large number of them join the mean value of this probability closer to the macroscopic movement.

Let's examine the claims.

A) False. The macroscopic motion of objects is the mean value of the microscopic motion, which with increasing size is deterministic and predictable.

B) True. Subatomic particles follow the rules of the Schrodinger equation and macroscopically Newton's second law.   Inconsequently they use different laws or to describe

C) False the most important force is electrostatic.

D) false. Large particles can be measured with a ruler, but sublimation that are orders of magnitude smaller require instruments of great pressure and complexity.

In conclusion using the characteristics of the subatomic particle we can find what the correct answer is;  

B)  Subatomic particles don’t follow the same laws of physics as large objects.
