which of the following has the largest radius k,Na+,Na,k+

Answer:

Explained below

Explanation:

1) Hydrogen bonds are formed between molecules

All these is because the bonds are flexible in such a manner that in the liquid phase, the molecules are relatively close to each other.

However, it is also noted that the hexagonal arrangement of ice is formed the bonds will be locked in place which will result in the average distance between molecules actually increasing which in turn means given a result that ice is less dense than liquid water.

B) Water possesses a high boiling point: This is because the Hydrogen oxygen bond or O-H bonds are highly polar and the Hydrogen atoms in this bond are located at two corners of the tetrahedron shaped like bond shape which gives water it's high molecular polarity in which in turn makes the molecules to stick together.

Answer:

\( \boxed{ \sf \: 3-propyl-hept-1-yne}\)

Explanation:

To know the name of Alkyne, use IUPAC(International Union of Pure and Applied Chemistry).

According to IUPAC, for the naming of any organic compound containing a triple bond, find the longest chain that contains triple bond & number the chain from the side where triple bond gets lowest number.

in the above diagram, the parent chain cobtains seven carbon atoms with a propyl substituent at 3rd carbon atom. during naming of the compound mention the substituent first along with the position of carbon where is it. Now 7 carbon Atom have prefix (-hept) and Alkyne group is on the first position hence the parent chain would be (hept-1-yne) and substituent (3-propyl).

hence the name of compound is 3-propyl-hept-1-yne

Explanation:

the oxygen in the air and water from the rain caused oxidation causing the copper wire to become tarnished.

The statement that describes a change resulting from the chemical properties of the wire is it becomes tarnished. The correct option is C.

Chemical properties are those properties that are not always shown physically, but they came out of a chemical reaction. Chemical properties are pH, solubility, toxicity, the heat of combustion, flammability, reactivity, etc.

The copper wire, when left out in the environment, becomes tarnished, due to the air and moisture present in the environment. The meaning of tarnished means it loses its luster or its quality.

Copper is a shiny, soft, and brown-colored metal. It is usually used in making wire used for electricity.

Thus, the correct option is C. It becomes tarnished.

4) The compounds as they have been shown are diastereomers

5) The compounds as they have been shown are enantiomers

6) The charges on the cyanide carbon and the bromine ion are negative , negative

We know that the optical isomers are the compounds that are mirror images of each other. These images could be super impossible or non super imposible. When the compounds are non super impossible images we call them enantiomers but is they are super impossible mirror images we call them diastereomers.

Recall that both diastereomers and enantiomers are all kinds of stereoisomers. These are isomers that have the same molecular formula but different arrangement of the atoms in space.

Thus we could have enantiomers when we have mirror images and diastereomers when we do not have mirror images.

To find out how many moles is 1.5x10^23 atoms of Carbon, we will use Avogadro's number, which is represented by 6.022x10^23 atoms or molecules per mol.

To convert from atoms to moles, divide the atoms by Avogadro's number.

So, now we can convert the numbers into proper form:

1.5x10^23 ---> 1.5E23

6.022x10^23 ---> 6.022E23

Then, we divide them.

1.5E23/6.022E23 = 0.24908

Round to nearest hundredth.

0.24908 --> 0.25

Therefore, there are 0.25 moles of carbon in 1.5E23 atoms of carbon.

Answer:

pH = 1.05

Explanation:

A solution of sulfuric acid, H₂SO₄, dissociates in water as follows:

H₂SO₄ → 2H⁺ + SO₄²⁻

That means per mole of H₂SO₄ you will have 2 moles of H⁺

pH = -log [H⁺]

As [H₂SO₄] = 0.045M and [H⁺] = 2×[H₂SO₄]

[H⁺] = 0.090M

pH = -log [0.090M]

The inertia of a bowling ball is greater than​ the inertia of a golf ball.

In Newton's first law, it is stated that if the resultant force acts on an object of magnitude is zero, it can be formulated:  

\(\large{\boxed{\bold{\sum F=0}}\)

then the object tends to defend itself from its state.  

or can be stated:  

An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.  

So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called inertia  

The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.  

Objects that have more mass will have more ability to maintain their state

So a larger bowling ball mass will have greater inertia than a golf ball

250 L of 5.0% w/v glucose solution can be prepared using 125 g of glucose.

w/v = [ mass of solute (g) / volume of solution (mL) ] × 100

5.0 % w/v = [ 125 g / volume of solution (mL) ] × 100

volume of solution (mL) = [ 125 g / 5.0 % w/v ] x 100

volume of solution (mL) = [ 125 g / (5.0 / 100) ] x 100

volume of solution (mL) = [ 125 g / 0.05 ] x 100

B. CH4(g) + H₂O(g) → CO(g) + 3H₂(g)

Explanation:

The increase in the number of moles of gas is a good indicator of an increase in entropy. Therefore, the reaction that produces more moles of gas than it consumes will have an increase in entropy.

A. 2H₂S(g) + 30₂(g) → 2H₂O(g) + 2SO2(g)

In this reaction, the number of moles of gas on the left side is 3, and on the right side, it is also 3. Thus, there is no change in the number of moles of gas, and there is no increase in entropy.

B. CH4(g) + H₂O(g) → CO(g) + 3H₂(g)

In this reaction, the number of moles of gas on the left side is 2, and on the right side, it is 4. Thus, there is an increase in the number of moles of gas, and there is an increase in entropy.

C. 2NO(g) + 2H₂(g) → N₂(g) + 2H₂O(g)

In this reaction, the number of moles of gas on the left side is 4, and on the right side, it is 3. Thus, there is a decrease in the number of moles of gas, and there is no increase in entropy.

D. 2CO(g) + 2NO(g) → 2C0₂(g) +N₂(g)

In this reaction, the number of moles of gas on the left side is 4, and on the right side, it is also 4. Thus, there is no change in the number of moles of gas, and there is no increase in entropy.

Therefore, the only reaction that has an increase in entropy is B. CH4(g) + H₂O(g) → CO(g) + 3H₂(g).

It is likened to a fictional scenario in which a team of scientists and "sci-operatives" are working on upgrading their Battle Armor to withstand the attacks from a fictional entity called "THE HIVE."

The team is using thermodynamics, the study of heat energy and its transformations, to analyze the effectiveness of the materials used in the Battle Armor, including silver.

In this scenario, Mr. Pauling is creating a report that analyzes the heating curve for silver, which is used in the Battle Armor. The heating curve shows the changes in temperature over time as heat energy is added, and it helps to determine the melting and boiling points of the substance, as well as the conditions needed for a phase change.

It seems like the purpose of the activity is to understand the use of thermodynamics in analyzing the effectiveness of materials in the Battle Armor, and to look for messages from Mr. Pauling regarding any unfinished parts of the report.

We can see from the equation that 2 moles of aluminum hydroxide produce 3 moles of water. We can also see that the molar mass of aluminum hydroxide is 78.00 g/mol.

We are given that 2.4 x 10^25 molecules of water are produced. We can convert this to moles by dividing the number of molecules by Avogadro's number:

2.4 x 10^25 molecules H2O / 6.022 x 10^23 molecules/mol H2O = 4.0 x 10^2 moles H2O

We can then use the molar ratio of aluminum hydroxide to water to calculate the mass of aluminum hydroxide that is needed:

4.0 x 10^2 moles H2O / 3 moles H2O/ 2 moles Al(OH)3 = 4.0 x 10^2 moles Al(OH)3

We can then use the molar mass of aluminum hydroxide to calculate the mass of aluminum hydroxide that is needed:

4.0 x 10^2 moles Al(OH)3 * 78.00 g/mol Al(OH)3 = 3.12 x 10^3 g Al(OH)3

Therefore, 3.12 x 10^3 g of aluminum hydroxide are needed to decompose in order to produce 2.4 x 10^25 molecules of water at STP.

What is Molecules?

A molecule is a group of two or more atoms that are chemically bonded together. Atoms can combine to form molecules by sharing electrons between them, forming a covalent bond. Molecules can also be formed by the attraction between oppositely charged ions, known as ionic bonding.

Molecules can be made up of atoms of the same element or atoms of different elements. For example, oxygen gas (O2) is a molecule made up of two oxygen atoms, while water (H2O) is a molecule made up of two hydrogen atoms and one oxygen atom.
