If you dilute a 10.0 mL of a 11.5 M HCl solution to make a 1.10 M HCl solution, what will the final
volume be?

Answers

Explanation:

The final volume will be 100 mL. This is because when you dilute a solution, the molarity of the solution decreases while the volume increases. Since the molarity of the original solution is 11.5 M and the desired molarity is 1.10 M, the volume must increase by a factor of 10.5 (11.5/1.10). Therefore, the final volume will be 10.0 mL x 10.5 = 100 mL.

How many moles of CaCl₂ would there be in 42 mL of 2.09 M aqueous CaCl₂ solution?
3 significant figures

Answers

Answer:

0.0878 moles CaCl₂

Explanation:

To find the amount of moles of CaCl₂, you need to

(1) convert the volume from mL to L (1,000 mL = 1 L)

(2) calculate the amount of moles (M = moles / L)

It is important to arrange the conversions in a way that allows for the cancellation of units.

(Step 1)
   

  42 mL CaCl₂                    1 L
------------------------  x  ----------------------  =  0.042 L CaCl₂
                                       1,000 mL

(Step 2)

Molarity (M) = moles / volume (L)                <----- Molarity ratio

2.09 M = moles / 0.042 L                            <----- Insert values

0.0878 = moles                                           <----- Multiply both sides by 0.042 L

carbon disulfide burns in oxygen to yield carbon dioxide and sulfur dioxide according to the fallowing chemical equation Cs2+3O2=CO2+2SO2

Answers

A. The limiting reactant would be oxygen.

B. The mole of excess reactant ([tex]CS_2[/tex]) would be 0.67 mol.

C. 0.33 mol [tex]CO_2[/tex] and 0.67 mol [tex]SO_3[/tex]  would be formed.

Stoichiometric problem

Carbon disulfide burns in oxygen to produce carbon dioxide and sulfur dioxide according to the balanced equation below:

[tex]CS_2(l) + 3O_2(g) -- > CO_2(g) + 2SO_2(g)[/tex]

The mole ratio of the carbon disulfide and the oxygen gas is 1:3. In other words, every mole of [tex]CS_2[/tex] requires 3 moles of [tex]O_2[/tex] for complete combustion.

A. From the established mole ratio, if 1.00 mol of [tex]CS_2[/tex] reacts with 1.00 mol of [tex]O_2[/tex], the limiting reactant would be [tex]O_2[/tex] because 3 moles of it are required for every mole of [tex]CS_2[/tex].

B. The excess reactant is, thus, [tex]CS_2[/tex]. 1.00 mol of [tex]O_2[/tex] would require:

3 mol [tex]O_2[/tex] = 1 mol [tex]CS_2[/tex]

1 mol [tex]O_2[/tex] = 1 x 1/3

               = 0.33 mol of [tex]CS_2[/tex]

But 1 mole of [tex]CS_2[/tex] reacted. The excess mole of [tex]CS_2[/tex] would be: 1 - 0.33 = 0.67 mol.

C. From the equation of the reaction, 3 mole of oxygen produces 1 mole of [tex]CO_2[/tex]. Thus, 1 mole of oxygen would produce:

3 mol [tex]O_2[/tex] = 1 mol [tex]CO_2[/tex]

1 mol [tex]O_2[/tex] = 1 x 1/3

              = 0.33 mol [tex]CO_2[/tex]

Also, 3 mol oxygen produces 2 moles [tex]SO_2[/tex]. Then 1 mol oxygen will produce:

2 x 1/3 = 0.67 mol

Thus, 0.33 mol [tex]CO_2[/tex] and 0.67 mol [tex]SO_3[/tex] will be formed from 1 mol of [tex]O_2[/tex].

Where do stars form?

Answers

Stars form in large, dense regions of gas and dust known as molecular clouds. These clouds are located primarily in the spiral arms of galaxies, where they are exposed to intense radiation from nearby stars. As the gas and dust in these clouds are subjected to this radiation, they begin to collapse under their own gravity. As the collapse continues, the cloud becomes denser and denser, and eventually a protostar forms at its center. Over time, this protostar continues to contract and heat up, eventually reaching the point where nuclear fusion can begin in its core. At this point, the protostar becomes a fully-fledged star, and the process of star formation is complete.

TL;DR: Within the clouds of dust and scattered throughout most galaxies.

Stars are born within the clouds of dust and scattered throughout most galaxies.

What is a solution?

A homogenous mixture of one or more solutes that have been dissolved in a solvent is known as a solution. The material that a solute dissolves in to create a homogenous mixture is known as a solvent.

The component that dissolves in a solvent to create a homogenous mixture is known as a solute.

M₁ is the initial concentration of HCl solution = 12.0 M

V₁ is the volume of initial HCl solution that is needed

M₂ is the final concentration of HCl solution = 1.5 M

V₂  is the final volume of HCl solution to be prepared = 3.0 L

To find V₁, we get

V₁ = (M₂ V₂) / M₁

calculating the values, we will get:

V₁ = 1.5 M x 3.0 L / 12.0 M

= 0.375 L

Therefore, tech required to take 0.375 L of the 12.0 M HCl solution and dilute it to  3.0 L to make a 1.5 M HCl solution.

hydrochloric acid?

Answers

The mass of [tex]H_2[/tex] that will be formed when 35.25 g Al reacts with excess hydrochloric acid would be 3.93 g.

Stoichiometric problem

The equation of the reaction of aluminum metal with hydrochloric acid to produce hydrogen gas is represented below:

[tex]2Al + 6HCl -- > 2AlCl_3 + 3H_2[/tex]

From the equation, one would see that the mole ratio of aluminum to the hydrogen gas produced is 2:3.

Now, with 35.25 g of aluminum, recall that: mole = mass/molar mass.

The molar weight of aluminum is 27 g/mol.

Thus:

Mole of 35.25 g Al = 35.25/27

                                = 1.31 mol

From the mole ratio, the mole of hydrogen that will be produced would be:

3/2 x 1.31 =1.97 mol

The molar mass of [tex]H_2[/tex] is 2 g/mol, the mass of 1.97 mol hydrogen gas can be calculated as:

Mass = mole x molar mass

         = 1.97 x 2

        = 3.93 grams

250 ml of a salt solution with a concentration of 15 g/l is mixer with 220 mL of salt solution containing 6% salt (m/v). What is the final concentration of salt in the solution in g/l

Answers

The final mass concentration of salt in the solution in g/l is 36.06 g/L.

What is the concentration of the mixture of the two salt solutions?

The mass concentration of the mixture of the two salt solutions is calculated as follows:

Concentration of solution 1 = 15 g/l

mass of salt in the 250 mL solution = 15 g/l * 250 mL * 1 L/1000 mL

mass of salt in the 250 mL solution = 3.75 g

Concentration of solution = 6% (m/v)

This means that in 100 mL solution, 6 g of salt in present.

In 1000 mL or 1 L solution, 60 g of salt will be present.

Hence, the concentration of solution = 60 g/L

mass of salt in the 220 mL solution = 60 g/l * 220 mL * 1 L/1000 mL

mass of salt in the 220 mL solution = 13.2 g

Total mass of salt in the mixture = 16.95 g

Total volume of solution = 470 mL

mass concentration = mass / volume in L

Final mass concentration of solution = 16.95 g / 470 mL * 1000 mL/L

Final mass concentration of solution = 36.06 g/L

Which of the following is best for determining the type of bond that will form between atoms when forming a compound?

Answers

One way to predict the type of bond that forms between two elements is to compare the electronegativities of the elements. In general, large differences in electronegativity result in ionic bonds, while smaller differences result in covalent bonds.

Answer: Best way is Electronegativity.

Explanation:

Comparing the electronegativities of the two elements is one method of predicting the type of bond that will form between them. Ionic bonds typically result from significant differences in electronegativity, whereas covalent bonds typically result from smaller differences.

The kind of covalent bond that forms between two atoms depends on how many pairs of electrons are shared by them. There are some factors that determine the type of bonds.

Simply how they share electrons makes a difference between different binding kinds. Ionic bonds don't share at all, polar bonds share unevenly, and covalent bonds share equally. Following are the variables that affect the kind of bond that will form between two atoms:
