A neutralization reaction occurs between sodium hydroxide and sulfurous acid. Complete the equation below for the neutralization reaction that ocurs during the titration

Answers

Answer 1

Answer:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

Explanation:

When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):

NaOH + H₂SO₃ → H₂O + Na₂SO₃

To balance the sodiums:

2NaOH + H₂SO₃ → H₂O + Na₂SO₃

And the hydrogens:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

And this is the complete reaction for this neutralization reaction.

A rubber ball contains .570 mL of gas at a pressure of 2.05 atm. What volume will the gas Couoh at 7.47 atm?

Answers

Answer:

the volume that the gas occupy at 7.47 atm is  0.1564 liters

Explanation:

The computation of the volume that the gas occupy at 7.47 atm is shown below:

As we know that

P1V1 = P2V2

Now

V2 = P1V1 ÷ P2

= 2.05 atm × 0.570 liters ÷ 7.47 atm

= 0.1564 liters

Hence, the volume that the gas occupy at 7.47 atm is  0.1564 liters

So the same would be considered and relevant

4.6 moles of a gas are at a temperature of 325 K and a volume of 96.8 L, what is the pressure of the gas

Answers

Answer:

1.27atm is the pressure of the gas

Explanation:

Using combined gas law, we can find the pressure of a gas with the moles, temperature and volume of the gas. The formula is:

PV = nRT

P = nRT / V

Where P is pressure in atm

n are the moles of the gas: 4.6 moles

R is gas constant: 0.082tamL/molK

T is absolute temperature: 325K

V is volume: 96.8L

Replacing:

P = 4.6mol*0.082atmL/molK*325K / 96.8L

P = 1.27atm is the pressure of the gas

If you react 59.54 g of S and 78 g of HNO3, how many grams of NO2 can you

How many molecules are in 6.20 moles of CaCO3?

Answers

1 mole is equal to 1 moles CaCO3, or 100.0869 grams.

What is mole?

A mole is just a measuring scale. In reality, it's one of the International System of Units' seven foundation units (SI). When already-existing units are insufficient, new ones are created.

The mole is a SI unit that is used to quantify any quantity of a substance. The word "mole" is shortened to "mol".

A mole consists of precisely 6.022140761023 particles. The "particles" could be anything, from tiny things like electrons or atoms to enormous things like stars or elephants.

Therefore, 1 mole is equal to 1 moles CaCO3, or 100.0869 grams.

Cd(s)+2HCI(aq)---- H2(g)+CdCl2(aq). what volume in liters of 0.81m HCI solution would be needed to fully react with 32.71g Cd. answer only please​

Answers

Answer:

0.718L of 0.81M HCl are required

Explanation:

Based on the reaction:

Cd(s)+2HCI(aq) → H2(g)+CdCl2(aq)

1 mol of Cd reacts with 2 moles of HCl

To solve this question we must, as first, find the moles of Cd. With the moles of Cd we can find the moles of HCl needed to react completely with the Cd. With the moles and the molarity we can find the volume:

Moles Cd -Molar mass: 112.411g/mol-:

32.71g * (1mol / 112.411g) = 0.2910 moles Cd

Moles HCl:

0.2910 moles Cd * (2 moles HCl / 1mol Cd) =

0.5820 moles HCl

Volume:

0.5820 moles HCl * (1L / 0.81moles) =

0.718L of 0.81M HCl are required

What is the oxidation number for S in the compound SO3? (Recall that O has an oxidation number of –2.) A. 0

Answers

Answer:

[tex]\boxed {\boxed {\sf +6}}[/tex]

Explanation:

A compound must have a net charge of 0. The charges have to balance each other out and equal 0.

We have the compound sulfur trioxide with a chemical formula of SO₃.

Oxygen (O) has an oxidation state of -2, which means it will have a charge of -2 in the compound. However, note there is a subscript after the O in the chemical formula. Therefore, there are 3 oxygen atoms in the compound and each one has a charge of -2. The oxygen has an overall charge of -6 because 3*-2 = -6.

There is only one atom of sulfur (there is no subscript, so a 1 is implied). It has to balance out the -6 charge of the oxygen atoms, so it must be +6.

The oxidation number for sulfur is +6 in the compound sulfur trioxide.

What amount of heat is released when the temperature of 450.0 g of a
substance drops by 7.1 °C? Assume that the specific heat = 1.264 J/g.°C

Answers

Answer:

[tex]\boxed {\boxed {\sf 4038.48 \ Joules}}[/tex]

Explanation:

Since we are given the mass, specific heat, and change in temperature, we should use this formula for heat:

[tex]q=mc\Delta T[/tex]

The substance's mass is 450.0 grams, the specific heat is 1.264 J/g°C, and the  change in temperature is 7.1 °C.

[tex]m= 450.0 \ g \\c= 1.264 \ J/g \textdegree C\\\Delta T= 7.1 \ \textdegree C[/tex]

Substitute the values into the formula.

[tex]q= (450.0 \ g)(1.264 \ J/g \textdegree C)(7.1 \ \textdegree C)[/tex]

Multiply the first 2 values together. The grams will cancel out.

[tex]q= 568.8 \ J/ \textdegree C (7.1 \ \textdegree C)[/tex]

Multiply again. This time, the degrees Celsius cancel out.

[tex]q= 4038.48 \ J[/tex]

4038.48 Joules of heat energy are released.

The standard molar enthalpy of vaporization for water is 40.79kJ/mol. What mass of steam is required to release 500 kJ of energy upon condensation?

Answers

Answer:

220.9g of water are required

Explanation:

The molar enthalpy of vaporization is defined as the heat released when 1 mole of water changes from liquid to gas.

For water, 1 mole releases 40.79kJ. To release 500kJ are necessaries:

500kJ * (1mol / 40.79kJ) = 12.26 moles are necessaries

To convert moles to grams we must use the molar mass (H2O = 18.02g/mol):

12.26 moles * (18.02g / 1 mol) =

220.9g of water are required

The reaction of perchloric acid (HClO4) with lithium hydroxide (LiOH) is described by the equation: HClO4 + LiOH → LiClO4 + H2O Suppose 100 mL of perchloric acid is neutralized by exactly 46.9 mL of 0.75 M lithium hydroxide. What is the concentration of the perchloric acid?

Answers

Answer:

[HClO₄] = 0.35 M

Explanation:

Neutralization reaction is:

HClO₄ + LiOH  →  LiClO₄  +  H₂O

In this case, we have a titration between a weak acid and a strong base.

In chemistry it is also called an acid base equilibrium.

HClO₄  +  H₂O  ⇄  ClO₄⁻   +  H₃O⁺       Ka

The weak acid is firstly neutralized by the strong base, in order to have a buffer solution before the equivalence point.

When we reach the equivalence point, mmoles of acid = mmoles of base and there is a formula to determine it so:

M acid . Volume of acid = M base . Volume of base

M acid . 100 mL = 0.75 M . 46.9 mL

M acid = (0.75 M . 46.9 mL) / 100 mL → 0.35 M

How much energy is released when 6.0 g of water is condensed from water to vapor?

Answers

Answer:6.0g x 1 mol/18.02g x 40,65 kJ/mol

Explanation: just did the quiz

13.6 kilojoules (kJ) of energy is released when 6.0 g of water is condensed from water to vapor.

To calculate the energy released when 6.0 grams of water is condensed from water to vapor, we need to use the concept of heat of vaporization (also known as enthalpy of vaporization). The heat of vaporization is the amount of energy required to change one gram of a liquid into vapor at its boiling point, without any change in temperature.

The heat of vaporization of water is approximately 40.7 kJ/mol at its boiling point (100°C or 373.15 K). We can use this information to calculate the energy released when 6.0 grams of water is condensed.

Step 1: Calculate the number of moles of water (H₂O) in 6.0 grams.

Molar mass of water (H₂O) = 2 g/mol (for hydrogen) + 16 g/mol (for oxygen) = 18 g/mol

Number of moles of water = Mass of water / Molar mass of water

Number of moles of water = 6.0 g / 18 g/mol = 0.333 moles

Step 2: Calculate the energy released during condensation.

Energy released = Number of moles of water × Heat of vaporization

Energy released = 0.333 moles × 40.7 kJ/mol = 13.6 kJ

Therefore, approximately 13.6 kilojoules (kJ) of energy are released when 6.0 grams of water is condensed from water to vapor.
