What is the difference between the structure of simple and complex carbohydrates?

Answer: D. The exponents determine how much concentration changes affect the reaction rate.

Explanation: This is correct. The exponents in the rate law do determine how much the concentration changes impact the reaction rate.

Option A i.e. The effect of concentration changes on the rate constant affects the reaction rate.

what is rate constant?

The proportionality constant, which explains the link between the molar concentration of the reactants and the pace of a chemical reaction, is known as the rate constant. The rate constant, also known as the reaction rate constant or reaction rate coefficient, is indicated by the letter k. Because reactant concentrations decrease as reactants are transformed to products, reaction speeds typically decrease over time. When reactant concentrations are raised, reaction rates generally increase. The temperature has an impact. The following are two methods for calculating rate constant:

Answer:

Density, d = 5.96 g/mL

Explanation:

Given that,

Mass, m = 105 g

Volume, V = 17.6 mL

We need to find the density of the substance. So,

[tex]d=\dfrac{m}{V}\\\\d=\dfrac{105\ g}{17.6\ mL}\\\\d=5.96\ g/mL[/tex]

So, the density of the substance is 5.96 g/mL.

Answer:

385g LiOH

Explanation:

Assuming the equation is balanced...

(8.03 mol Li2SO4) x (2 LiOH/ 1 Li2SO4)

= 16.1 mol LiOH ;

16.1 mol LiOH x (24g LiOH/ 1 mole LiOH) = 385g LiOH

The number of moles of LiOH needed to produce 8.03 moles is 16.06 moles. One mole of LiOH weighs, 23 g/mol. Hence, 16.06 moles weighs, 369.3 g.

Lithium sulphate is an ionic compound formed by the donation of electron from the lithium metal to the sulphate group. It is formed by the reaction of lithium hydroxide with sulphuric acid.

As per the given balanced chemical equation of the reaction, the 2 moles of lithium hydroxide LiOH gives one mole of lithium sulphate. Then, number of moles of LiOH needed to give 8.03 mol of the product is:

2 × 8.03 = 16.06 mol.

Molar mass of LiOH = 23 g/mol.

mass of 16.06 moles of LiOH = 23 ×16.06 = 369.3 g.

Therefore, the required mass LiOH is 369.3 g.

Explanation:

The distance that Neil Pogo travels is 16 meters. While the displacement is Zero (0).

Displacement may be defined as the distance traveled by an object from the initial point to the final point. It is a vector quantity and has a direction and magnitude. In a more simple sense, it is known to be the alteration of the position of the object.

According to the question,

The total distance covered by Neil Pogo = 8 m east then 8 m west = 16 meters.

But according to the definition of displacement, his total displacement was zero. This is because the distance between his initial point and the final point is zero.

He returned back to the same place indicating his zero displacements.

Therefore, the distance that Neil Pogo travels is 16 meters. While the displacement is Zero (0).

Answer:

20.95 g of caffeine, C₈H₁₀N₄O₂

Explanation:

From the question given above, the following data were obtained:

Number of molecules of C₈H₁₀N₄O₂ = 6.5×10²² molecules

Mass of C₈H₁₀N₄O₂ =?

From Avogadro's hypothesis,

1 mole of C₈H₁₀N₄O₂ = 6.02×10²³ molecules

Next, we shall determine the mass of 1 mole of C₈H₁₀N₄O₂. This can be obtained as follow:

1 mole of C₈H₁₀N₄O₂ = (8×12) + (10×1) + (4×14) + (2×16)

= 96 + 10 + 56 + 32

1 mole of C₈H₁₀N₄O₂ = 194 g

Thus,

194 g of C₈H₁₀N₄O₂ = 6.02×10²³ molecules

Finally, we shall determine the mass of caffeine, C₈H₁₀N₄O₂ that contains 6.5×10²² molecules. This can be obtained as follow:

6.02×10²³ molecules = 194 g of C₈H₁₀N₄O₂

Therefore,

6.5×10²² molecules = (6.5×10²² × 194) / 6.02×10²³

6.5×10²² molecules = 20.95 g of C₈H₁₀N₄O₂.

Therefore, 20.95 g of caffeine, C₈H₁₀N₄O₂ contains 6.5×10²² molecules

Answer:

The volume of a 0.2 M solution containing 8.5 grams of AgNO₃ is 0.25 L

Explanation:

 Molarity (M) is a common way of expressing the concentration of solutions. It is defined as the number of moles of solute per volume of solution. The molarity of a solution is calculated 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 the molar mass of AgNO3 169.87 g / mol, then you can apply the following rule of three: if 169.87 grams are present in 1 mole of the compound, 8.5 grams will be present in how many moles?

[tex]amount of moles=\frac{8.5 grams*1 mole}{169.87 grams}[/tex]

amount of moles= 0.05

So, being the molarity equal to 0.2 M, replacing in the definition of molarity:

[tex]0.2 M=\frac{0.05 moles}{volume}[/tex]

and solving you get:

[tex]volume=\frac{0.05 moles}{0.2 M}[/tex]

volume=0.25 L

The volume of a 0.2 M solution containing 8.5 grams of AgNO₃ is 0.25 L

Each of the following organs had a role in excretion, except for the Heart. Therefore, the correct option is option C.

Excretion seems to be the process throughout which an organism eliminates metabolic waste. In vertebrates, this is largely done by that of the skin, kidneys, especially lungs. When a substance is secreted, this could perform certain roles once it leaves the cell. Excretion is required by all forms of life.

Animals, for example, use the urethra, a member of the excretory, to evacuate urine. In unicellular organisms, waste products are ejected quickly via the cell surface. During biological functions, such as cellular respiration, a variety of chemical changes occur in the body. Each of the following organs had a role in excretion, except for the Heart.

Explanation:

Show drawing

Skeletal structural diagram and bond-line drawing are similar;

Parts of the question appear missing: The number of hydrogen atoms in the attached example bond-line drawing is 6 hydrogen atoms

The reason the above value is arrived at for the attached example bond-line diagram is as follows;

A bond-line drawing is the diagram showing the molecular structure of a compound, such that covalent bonds within the molecule are represented by lines with the number of lines indicating the number of covalent bonds.

A single covalent bond is represented by one line, double bonds by two lines while three parallel lines represents a triple bond.

In bond-line drawing, the lines symbolically infer the carbon to carbon bonds while the bonds to the hydrogen atoms are implied noting that each carbon has four covalent bonds. Hydrogen atoms attached to other heteroatoms are indicated with an H.

The number of hydrogen shown in the example diagram can be found by noting that the number of covalent bonds between the carbon atoms are three, therefore, the atom of the fourth bond not shown with a line is to a hydrogen atom

There are six such carbon atoms, one of which is attached to an oxygen atom, which gives five hydrogen atoms located on the ring

There is one more hydrogen atom attached to the oxygen in the hydroxyl group, the total number of hydrogen is therefore;

5 hydrogen on ring + One hydrogen in the hydroxyl group = 6 hydrogen atoms
