how much iodine (I2) in moles, should be added to water to produce 2.5L of solution with a molarity of 0.6M?

Answers

Answer 1

Molar concentration or Molarity is a way to measure the concentration of a solution after some solute has been added to the solvent, the formula for Molarity is:

M = n/V

where:

M = molar concentration

n = number of moles

V = volume of the solution in Liters

In the question we are given the molarity and volume, let's add these information to our formula

0.6 M = n/2.5 L

n = 1.5 moles of Iodine should be added

If you need 300g of NH3 how many liters of N2 are required? N2+3H2=2NH3

Answers

Answer:

197.12L of N2 are required.

Explanation:

1st) From the balanced reaction we know that 1 mol of N2 reacts with 3 moles of H2 to produce 2 moles of NH3.

2nd) It is necessary to convert moles to grams with the molar mass, and use the stoichiometry of the balanced reaction to find the amount of N2 moles that are required to produce 300g of NH3:

- N2 molar mass: 28g/mol

- NH3 molar mass: 17.01g/mol

[tex]300gNH_3*\frac{1mol}{17.01g}=17.64mol[/tex]

300g of NH3 is equal to 17.64 moles of NH3.

3rd) Now, with a mathematical rule of three we can find the moles of N2 that are required to produce 17.64 moles of NH3:

[tex]\begin{gathered} 2molesNH_3-1molN_2 \\ 17.64molesNH_3-x=\frac{17.64molesNH_3*1molN_2}{2molesNH_3} \\ x=8.82molN_2 \end{gathered}[/tex]

Now we know that 8.82 moles of N2 are needed.

4th) Finally, using the molar volume value (22.4L), we can calculate the liters of N2 that are required.

The molar volume indicates that 1 mole is equivalent to a volume of 22.4L under normal conditions.

[tex]8.80mol*\frac{22.4L}{1mol}=197.12L[/tex]

So, 197.12L of N2 are required.

Topic sentence:

All matter is composed of atoms that are in constant motion, three types of motion can be identified translation, rotation, and vibration. These particles are so small that they cannot be observed even with the smallest microscope, but they are so important that depending on their motion and interaction with other particles will be their state and how we see them at the macroscopic level. The greater the movement of the molecules the greater the disorder, so we can distinguish three states of matter presented from greater to lesser disorder: gas, liquid and solid.

Gas:

The motion in gases presents the three types of movement: translation, rotation, and vibration, and is the most intense. In the case of gases, the particles are quite far apart compared to their size. The approximate average distance between particles, under normal conditions, is ten times the particle size. In gases the particles do not occupy fixed positions, they are disordered and move randomly vibrating, rotating, and moving in all directions.

Liquid:

Liquids also exhibit all three types of motion (translation, rotation, and vibration) but with less intensity than in gases. In liquids, the particles do not occupy fixed They are disordered, although less so than in gases, and move randomly, as in gases, but with less intensity.

Solid:

The cohesive forces in solids are strong, much greater than in liquids, which are weak, and practically non-existent in gases. In solids, the particles occupy fixed positions, are ordered, and have no translational or rotational motion, only vibration.

Concluding sentence:

For all states of matter, the pressure and temperature involved will affect the order of the molecules making it possible to pass from one state to another by changing these variables.

Answers

Answer

The resulting solution will be neutral.

Explanation

Given:

Volume of HClO4 = 60.0 mL = 0.06 L

Molarity of HClO4 = 0.0500 M

Volume of NaOH = 40.0 mL = 0.04 L

Molarity of NaOH = 0.0750 M

What to find:

To determine if the resulting solution from (HClO4 and NaOH) acidic, basic, or neutral.

Solution;

The first step is to write a balanced chemical equation for the reaction.

HClO4 + NaOH → NaClO4 + H2O

The reaction is a neutralization reaction (also a double displacement reaction). The strong acid (HClO4) and a strong base react to produce salt (NaClO4) and water (H2O).

The next step is to determine the moles of the acid and the base using the formula below:

[tex]\begin{gathered} Moles=Molarity\times Volume\text{ }in\text{ }L \\ \\ For\text{ }HClO_4: \\ \\ Moles=0.0500M\times0.06L=0.003\text{ }mol \\ \\ For\text{ }NaOH: \\ \\ Moles=0.0750M\times0.04L=0.003\text{ }mol \end{gathered}[/tex]

From the balanced chemical equation, 1 mol HClO4 neutralized 1 mol NaOH.

Therefore, 0.003 mol HClO4 will completely neutralize 0.003 mol NaOH and the resulting solution will be neutral.

Answers

Explanation:

To solve this question, we need to use the following equation:

M = n/V

where:

M = molarity

n = number in moles

V = volume

For trial 1 we have:

M of NaOH = 0.112 mol/L

n = ??

V = 7.18 mL (we need to transform it to L, just divide by 1000)

V = 0.718 L

So:

M = n/V

n = M*V

n = 0.112*0.718

n = 0.080 moles of NaOH

The equation of dissociation of NaOH is:

NaOH --> Na+ + OH-

0.080 0.080 0.080

Answer for trial one: 0.080 moles of OH- or 8.0x10^-2 moles

For trial 2 we have:

For trial 1 we have:

M of NaOH = 0.112 mol/L

n = ??

V = 7.20 mL (we need to transform it to L, just divide by 1000)

V = 0.720 L

So:

M = n/V

n = M*V

n = 0.112*0.720

n = 0.081 moles of NaOH

The equation of dissociation of NaOH is:

NaOH --> Na+ + OH-

0.081 0.081 0.081

Answer for trial two: 0.081 moles of OH- or 8.1x10^-2 moles

-4 AI (s) + 302(g)=2Al2O3(s)How many grams of Al2O3 can be formed from 43.91 g of Al and 54.13 g of O2?(Hint: You need to determine which one is the limiting reactant).

Answers

82.94g of Al2O3 will be produced.

1st) With the molar mass of each compound and the balanced equation, we need to find which reactant is the limiting reactant.

- Al molar mass: 27g/mol

- O2 molar mass: 32g/mol

- Al2O3 molar mass: 102g/mol

Calculation with Al:

According to the balanced equation, 108g of Al (4 x 27g) needs 96g of O2 (3 x 32g), so with a mathematical rule of three we can calculate the amount of oxygen that is needed to react with 43.91g of Al:

[tex]\begin{gathered} 108\text{gAl}-96gO_2 \\ 43.91\text{gAl}-x=\frac{43.91\text{gAl}\cdot96gO_2}{108\text{gAl}} \\ x=39.03gO_2 \end{gathered}[/tex]

Now we know that, 43.91g of Al will need 39.03g of O2 to react, and we have 54.13g of O2, so there is excess of oxygen.

Calculation with O2:

According to the balanced equation, 108g of Al (4 x 27g) needs 96g of O2 (3 x 32g), so with a mathematical rule of three we can calculate the amount of aluminum that is needed to react with 54.13g of O2:

[tex]\begin{gathered} 96gO_2-108gAl \\ 54.13gO_2-x=\frac{54.13gO_2\cdot108gAl}{96gO_2} \\ x=60.89\text{gAl} \end{gathered}[/tex]

Now we know that 54.13g of O2 will need 60.89g of Al to react, and we have only 43.91g of Al, so it is not sufficient, and that's why Al is the limiting reactant.

2nd) Now that we know that Al is the limiting reactant, we can calculate the grams of Al2O3 that will be produced in the reaction by using the limiting reactant (43.91g):

[tex]\begin{gathered} 108\text{gAl}-204gAl_2O_3 \\ 43.91\text{gAl}-x=\frac{43.91\text{gAl}\cdot204gAl_2O_3}{108\text{gAl}} \\ x=82.94gAl_2O_3 \end{gathered}[/tex]

In this calculation we use the balanced equation, so we know that 108g of Al will produce 204g of Al2O3 (2 x 102g).

Finally, 82.94g of Al2O3 will be produced from 43.91g of Al and 54.13g of O2.

Calculate the quantity (in grams) of sucrose (C12H22011) required to make a 1.00 M strength solution with a volume of 500. mL.

Answers

Let us first define the term molarity. Molarity is a way of expressing the concentration of a compound in solution and is defined as the number of moles per liter of solution.

We are given the molarity value, 1.00M, and the volume of the solution, 500 mL=0.5L. We can find the number of moles by clearing them from the following equation:

[tex]\begin{gathered} Molarity=\frac{MolesSolute}{Lsolution} \\ MolesSolute=Molarity\times Lsolution \end{gathered}[/tex]

We replace the known data:

[tex]\begin{gathered} MolesSolute=1.00M\times0.5L \\ MolesSolute=1.00\frac{mol}{L}\times0.500L=0.500molC_{12}H_{22}O_{11} \end{gathered}[/tex]

Now, the grams of sucralose are found by multiplying the moles found by the molar mass of sucralose, which is 342.3 g/mol:

[tex]gC_{12}H_{22}O_{11}=0.500molC_{12}H_{22}O_{11}\times\frac{342.3gC_{12}H_{22}O_{11}}{1molC_{12}H_{22}O_{11}}=171gC_{12}H_{22}O_{11}[/tex]

The quantity of sucrose required will be 171 g of sucrose
