For the reaction So3 + H2O -> H2SO4, how many grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid

Answers

Answer 1

Answer:

320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.

Explanation:

The balanced reaction is:

SO₃ + H₂O → H₂SO₄

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:

SO₃: 1 moleH₂O: 1 moleH₂SO₄: 1 mole

Being the molar mass of each compound:

SO₃: 80 g/moleH₂O: 18 g/moleH₂SO₄: 98 g/mole

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

SO₃: 1 mole* 80 g/mole= 80 gramsH₂O: 1 mole* 18 g/mole= 18 gramsH₂SO₄: 1 mole* 98 g/mole= 98 grams

Then you can apply the following rule of three: if 1 mole of sulfuric acid is produced by the reaction of 80 grams of sulfur trioxide, 4 moles of sulfuric acid is produced from how much mass of sulfur trioxide?

[tex]mass of sulfur trioxide= \frac{4 moles of sulfuric acid* 80 grams of sulfur trioxide}{1 mole of sulfuric acid }[/tex]

mass of sulfur trioxide= 320 grams

320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.

Answer 2

The mass of the required compound is 320 grams

Chemical reactions

Given the chemical equation expressed as:

[tex]SO_3 + H_2O \rightarrow H_2SO_4[/tex]

According to stochiometry, 1 mole of SO3  produces 1 mole of H2SO4, hence the moles of SO3 will also be 4.00moles

Determine the mass of SO3

Mass = mole * molar mass

Mass = 4.0 * [32+3(16)]

Mass = 4.0 * 80

Mass = 320 grams

The mass of the required compound is 320 grams

What theoretical yield of NaCl would result from reacting 3.00 moles of Na2CO3 with excess HCl (aqueous)?

Answers

Answer:

350.7 g of NaCl

Explanation:

For this reactions our reactants are:

HCl and Na₂CO₃.

Then, the reaction is:

2HCl + Na₂CO₃ →  2NaCl  +  H₂CO₃

2 moles of hydrochloric acid react to 1 mol of sodium carbonate in order to produce 2 moles of salt and 1 mol of carbonic acid.

Ratio is 1:2. 1 mol of sodium carbonate can produce 2 moles of NaCl

Then, 3 moles of carbonate may produce (3 . 2) /1 = 6

We convert the moles to mass to determine the theoretical yield

6 mol . 58.45g /mol = 350.7 g

The theoretical yield of NaCl produced is 350.7 g.

What is NaCl?

NaCl is a salt, and it is an ionic compound.

The reaction is

[tex]\rm 2HCl + Na_2CO_3 \rightarrow 2NaCl + H_2CO_3[/tex]

2 mol of HCl reacts with 1 mol of [tex]Na_2CO_3[/tex] and produces 2 mol of NaCl and 1 mol of [tex]H_2CO_3[/tex].

The ratio will be [tex]Na_2CO_3[/tex] : NaCl

                                1 : 2

Then, for 3 mol of [tex]Na_2CO_3[/tex]

[tex]\dfrac{3 \times 2}{1} = 6[/tex]

Now, convert the moles to mass

[tex]6\; mol \times 58.45g /mol = 350.7 g[/tex]

Thus, the theoretical yield produced is 350.7 g.

The molarity of a solution that contains 28 g KOH (molar mass 56 g/mol) per 250 mL of solution is:

Answers

Molarity = moles of solute/volume of solution in liters

The solute here is KOH. We have the mass of KOH, and we can calculate the number of moles by dividing by the molar mass: (28 g KOH)/(56 g/mol) = 0.5 mol KOH. The volume of our solution is 0.250 L.

So, the molarity of the solution would be (0.5 mol KOH)/(0.250 L) = 2 mol/L KOH or 2 M KOH.

What is the percent by mass of C in benzene (C6H6)? The molecular weight of carbon is 12.0107 g/mol and of hydrogen 1.00794 g/mol

Answers

Answer:

92.26% of C

Explanation:

To solve this problem we must assume we have 1 mole of benzene. The mole contains 6 moles of C and 6 moles of H. We have to convert these moles to grams in order to find the total mass and mass percent will be:

Mass atom / Total mass * 100

Mass C: 6mol C * (12.0107g / mol) = 72.0642g

Mass H: 6mol H * (1.00794g / mol) = 6.04764g

total mass: 72.0642g + 6.04764g = 78.11184g

Mass percent of C will be:

72.0642g C / 78.11184g* 100

92.26% of C

Answers

an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.

According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.

Number of moles of nitrogen  gas.

Solution :

We know, by ideal gas equation :

PV = nRT  ( R ( universal gas constant ) = 8.31 J K⁻¹ mol⁻¹ .

[tex]n = \dfrac{PV}{RT}\\\\n = \dfrac{144000\times 0.0289}{8.31 \times 328} \ moles\\\\n = \dfrac{4161.6}{2725.68}\\\\n = 1.53 \ moles[/tex]

Answers

Answer:

0.0025moles

Explanation:

Molarity of a solution (M) = number of moles (n) ÷ volume (V)

According to this question, to make 250 mL of a 0.01 M solution of CaCl, the following number of moles is needed:

Volume = 250mL = 250/1000 = 0.250Litres.

0.01 = n/0.250

n = 0.0025

n = 2.5 × 10^-3 moles.

A 1.5 L pocket of air with a temperature of 295 K rises in the atmosphere. What will be the volume of the air pocket of the t temperature decreased to 2 celsius and the pressure is not changed.

Answers

Answer:

1.4 L.

Explanation:

Applying Charles law,

V/T = V'/T'....................... Equation 1

Where V = Initial volume, V' = Final volume, T = Initial Temperature in Kelvin, T' = Final Temperature in Kelvin.

Make V' the subject of the equation

V' = (V/T)T'..................... Euqation 2

Given: V = 1.5 L, T = 295 K, T' = 2 °C = (2+273) K = 275 K

Substitute these values into equation 2

V' = (1.5/295)275

V' = 1.398

V' ≈ 1.4 L

what are the respective coefficients needed to balance the equation below _N2(g) + _H2(g) --> _NH3(g)

Answers

This is the answer:
N2+3H2=2NH3

In the balanced equation, the mass of reactant is exactly equal to the mass of product. The respective coefficients needed to balance the equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .

What is balanced equation ?

A chemical equation that is balanced has equal amounts of each element's atoms on both sides of the equation and conserves mass.

Because mass cannot be generated or destroyed, according to the rule of conservation of mass, a chemical equation must always be in balance.

The Law of Conservation of Mass is followed by a balanced equation. This is a crucial scientific guiding principle. Finally, a balanced equation enables us to forecast the quantity of reactants and products that will be produced. Sort of crucial if you're attempting to determine how much fuel to supply a spacecraft traveling to Mars

Thus, the balanced equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .

Calculate the molarity of a solution prepared by dissolving 6.87 grams of AgNO3 in enough water to make 2.50 liters of solution.

Answers

Answer:

The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]

Explanation:

Molar concentration is a measure of the concentration of a solute in a solution.

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

Molarity is determined by dividing the moles of the solute by the volume of the solution:

[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

Being 169.87 g / mole the molar mass of AgNO₃, then you can apply the following rule of three: if 169.87 grams are contained in 1 mole, 6.87 grams are contained in how many moles?

[tex]amount of moles=\frac{6.87 grams*1 mole}{169.87 grams}[/tex]

amount of moles= 0.04 moles

Then:

number of moles of solute: 0.04 molesvolume: 2.50 L

Replacing:

[tex]Molarity=\frac{0.04 moles}{2.50 L}[/tex]

Solving:

Molarity= 0.016 [tex]\frac{moles}{L}[/tex]

The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]

Answers

Answer:

weak bonds break and strong bonds form

Explanation:

An exothermic reaction is a chemical reaction in which heat energy is evolved during the reaction process.

Bond formation requires energy while bond breakage releases energy. More energy is needed for the formation of weak bonds as compared to strong bonds.

Hence, when weak bonds break, they release more energy than needed to make a corresponding strong bond leading to the release of the remaining energy as heat.
