How many Grams of ribose (a carbohydrate) must be added to
200 mL of water to prepare a O.IM ribose solution?

Answers

Answer 1

Answer:

3 grams C₅H₁₀O₅

Explanation:

To find the mass of ribose needed to prepare the sample, you need to

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

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

(3) convert moles to grams (using the molar mass of ribose)

The molecular formula of ribose is C₅H₁₀O₅. It is important to arrange all of the ratios/conversions in a way that allows for the cancellation of units.

(Step 1)

 200 mL C₅H₁₀O₅                   1 L
----------------------------  x  ----------------------  =  0.2 L C₅H₁₀O₅
                                           1,000 mL

(Step 2)

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

0.1 M = moles / 0.2 L                                     <----- Insert values

0.02 = moles                                                  <----- Multiply both sides by 0.2 L

(Step 3)

Atomic Mass (C): 12.011 g/mol

Atomic Mass (H): 1.008 g/mol

Atomic Mass (O): 15.999 g/mol

Molar Mass (C₅H₁₀O₅): 5(12.011 g/mol) + 10(1.008 g/mol) + 5(15.999 g/mol) = 150.13 g/mol

 0.02 moles C₅H₁₀O₅              150.13 g
----------------------------------  x  -------------------  =  3 grams C₅H₁₀O₅
                                                  1 mole

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:

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.

8. Interestingly, the 1s orbital in the chlorine atom encloses more volume of space than the 1s orbital in an argon atom. Explain.

Answers

Answer: Chorine's atomic radius in larger than that of Argon.

Explanation: Thinking in terms of atomic radius, as you move from left to right on the periodic table, atomic radius decreases. However, as you move from top to bottom on the periodic table, the atomic radius increases. This is because when you are moving from top to bottom on the periodic table, more orbitals are added. When you move from left to right, the number of orbitals remains the same but the number of protons in the nucleus is still increasing. They have a stronger hold on the electrons and pull them closer. This also makes it harder for outside photons to remove an electron from an atom (ionization energy) as you move from left to right on the periodic table.

Now let's think about chlorine and argon. They are right next to each other in the upper right-hand corner of the periodic table. However, chlorine does come first and if we think back to the atomic radius, it gets smaller as you move from left to right. Chlorine comes before Argon when looking left to right.

In conclusion, chorine's atomic radius is larger than that of argon.

Answers

Ideal gas law is valid only for ideal gas not for vanderwaal gas. To solve such, we need to know the relation between rate of effusion and molar mass of gases. Therefore, the molar mass of unknown gas is 53.6g/mol.

What is ideal gas equation?

Ideal gas equation is the mathematical expression that relates pressure volume and temperature.

Mathematically the relation between rate of effusion of gases and their molar masses can be given as:

rate of effusion of unknown gas/rate of effusion of carbon dioxide gas=√molar mass of carbon dioxide/molar mass of particular gas

rate of effusion of carbon dioxide=1.087 ×rate of effusion of unknown gas

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.

What mass of H2 forms when
35.25 g Al reacts with excess
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

In other words, the amount of [tex]H_2[/tex] that would be formed when 35.25 g All reacts with excess hydrochloric acid would be 3.93 g.

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].

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

Molar mass of CH = 12 + 1 = 13 g/mol

[tex]r_1[/tex] = 2.55

Gas 2 = CO

Molar mass = 12 + 16 = 28 g/mol

[tex]r_2[/tex] = ?

Making [tex]r_2[/tex] the subject of the formula and substituting the values into the equation:

2.55/[tex]r_2[/tex] = [tex]\sqrt\frac{28}{13}[/tex]

2.55/[tex]r_2[/tex] = 1.4676

[tex]r_2[/tex]        = 2.55/1.4676

          = 1.74 mL/min

In other words, the rate of effusion of CO at 2.00 atm in the same container would be 1.74 mL/min.
