The correct IUPAC name of the given alkyne (5-ethynyldecane) is 5-ethynyldec-1-yne.

An alkyne is an unsaturated hydrocarbon containing a triple bond between two carbon atoms. It has the general formula CnH₂n-2. The common names of alkynes are derived from the corresponding alkanes by replacing the suffix -ane with -yne. However, the IUPAC system provides a systematic and standard method of nomenclature for organic compounds. It is based on the longest carbon chain, functional group, and substituents present in the compound.

In the given alkyne, the longest carbon chain contains ten carbon atoms. The triple bond is present between the fifth and sixth carbon atoms from the left end. Therefore, the parent chain is decane and the triple bond is located between the fifth and sixth carbon atoms. The prefix ethynyl (-C≡C-) represents the substituent attached to the fifth carbon atom. Therefore, the IUPAC name of the given alkyne is 5-ethynyldec-1-yne.

The \(BrO_3^-\) ion is named bromate, which is an anion derived from the oxoacid \(HBrO_3\). The name of the oxoacid \(HBrO_3\) is bromic acid.

Here's the breakdown of the terms:
- Ion: An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
- Bromate: The \(BrO_3^-\) ion, an anion containing bromine and oxygen.
- Oxoacid: An acid containing oxygen, along with another element and hydrogen.

The hydrogen atom is bonded to one of the oxygen atoms via a single covalent bond. This makes the bromic acid a member of the oxoacid family, which consists of acids that contain oxygen and hydrogen atoms.
So,\(HBrO_3\) is an oxoacid with the bromate ion (\(BrO_3^-\)) and hydrogen (H⁺), and its name is bromic acid.

When an H atom absorbs an ultraviolet photon with the correct energy, the electron in the atom can undergo a transition from the fifth energy level (n=5) to the first energy level (n=1).

This type of transition is called a "quantum jump" and is associated with the emission of a photon. When an H atom absorbs an ultraviolet photon with the correct energy, it will move from its ground state to an excited state.

This excitation of the electron can then lead to further processes such as the emission of a photon or the formation of an ion-pair. Therefore the correct answer is D)n=5 to n=1 when the H atom absorbs an ultraviolet photon with the correct energy

4) 6.53×10²² molecules or formula units

5) 1.505×10²³ ions

6) 90.626 grams

7) 0.555 moles

Explanation:

1) The number of moles, n = Mass of the substance/(Molar mass of the substance)

The molar weight of PO₄⁻³ is 94.971 g/mol

The number of moles in 10.23 g of PO₄⁻³ is n =10.23/94.971 = 0.1077 moles

The number of moles in 10.23 g of PO₄⁻³ = 0.1077 moles

2) The number of molecules of Na₂CO₃ in one mole of Na₂CO₃ is given by the Avogadro's number, \(N_A\) = 6.02 × 10²³ molecules

Therefore, the number of moles in 8.25 × 10²⁸ molecules of Na₂CO₃ is found by determining how many Avogadro's number of molecules are in 8.25 × 10²⁸ molecules of Na₂CO₃ as follows;

The number of moles in 8.25 × 10²⁸ molecules of Na₂CO₃ = (8.25 × 10²⁸)/(6.02 × 10²³) = 137043.2 moles

The number of moles in 8.25 × 10²⁸ molecules of Na₂CO₃ = 137043.2 moles

3) The molar mass of CH₂O = 30.031 g/mol

Therefore, the mass of 6 of CH₂O = 6 moles × 30.031 g/mol = 180.186 grams

The mass of 6 of CH₂O = 180.186 grams

4) The molar mass of NaCl = 58.44 g/mol

The number of moles of NaCl in 6.34 g of NaCl 6.34/58.44 = 0.1085 moles

1 formula unit of NaCl = 1 molecule of NaCl

The number of molecules in one mole of  a substance =  \(N_A\) = 6.02 × 10²³

Therefore, the number of molecules in  0.1085 moles of NaCl = 6.02 × 10^(23) × 0.1085 = 6.53×10²² molecules or formula units

5) The number of ions per mole of any substance is give by Avogadro's number, \(N_A\) = 6.02 × 10²³ ions,

The number of ions in 0.25 moles of Cu⁺² = 0.25×6.02 × 10²³ ions = 1.505×10²³ ions

The number of ions in 0.25 moles of Cu⁺² =  1.505×10²³ ions

6) The molar mass of CH₄ = 16.04 g/mol

The number of moles, n, in 3.4×10²⁴ = 3.4×10^(24)/(6.02×10^(23)) = 5.65 moles 5.65*16.04

The mass of 5.65 moles of CH₄ = 5.65 moles × 16.04 g/mol = 90.626 grams

The mass of 3.4×10²⁴ molecules of CH₄ = 90.626 grams

7) The density of water = 1 g/mL

The volume of the water 10 mL

The mass of the water = Volume × Density = 10 mL × 1 g/mL= 10 grams

The molar mass of water = 18.015 g/mol

The number of moles of water in 10 g  of water = mass/(Molar mass) = 10/18.015 = 0.555 moles.

The type of solvent used with a marker can greatly affect the reaction and outcome of the marker. When selecting a solvent, it is important to consider the polar or non-polar nature of both the solvent and the marker in order to achieve the desired result.

Solvents are liquids that are used to dissolve substances and are an important aspect of chemical reactions and processes. When it comes to markers, the type of solvent used can greatly affect the reaction and outcome of the marker.

In general, solvents can be classified as polar or non-polar. Polar solvents, such as water, have a positive and negative end, while non-polar solvents, such as oil, have a more uniform distribution of electrons. The solubility of a substance is determined by its polar or non-polar nature and the polar or non-polar nature of the solvent.

Markers contain various types of dyes or pigments that can be either polar or non-polar. When a polar solvent, such as water, is used with a polar marker, the marker will dissolve easily, leading to a more intense and uniform color. On the other hand, when a non-polar solvent, such as alcohol, is used with a polar marker, the marker may not dissolve as well and the color may be lighter or less intense.

The pH when 15 ml of 0.26 m HCl is titrated with 45 ml of 0.10 m NaOH is 13.35.

HCL + NaOH » NaCl + H2O

Given

Volume of NaOH = 45 ml = 0.045 l.

Volume of HCl = 15 ml = 0.015 l.

Concentration of NaOH = 0.26 m

Concentration of HCL = 0.10 m

Number of moles = E × V

Where,

C = Concentration

V = Volume

Number of moles of HCl = 0.10 × 0.015 = 0.0015 mol

Number of moles of NaOH = 0.045 × 0.26

= 0.0117 mol

Remaining moles of NaOH = 0.0117 – 0.0015 = 0.0102 mol

Molarity of NaOH = 0.0102 / 0.045 = 0.22 m

[OH] = 0.22M

pOH = -log[OH-]

pOH = -log(0.22)

pOH= 0.65

As we know that

pH +pOH= 14

pH = 14-pOH

pH = 14-0.6

pH= 13.35

Thus, we found that the pH is 13.35 if 15 ml of 0.26 m HCl is titrated with 45 ml of 0.10 m NaOH.

Answer:

pH = 12.00

Explanation:

First, calculate the moles of acid in the solution:

(0.015 L )(0.26molL)=0.0039 mol acid

Next, calculate the moles of base:

(0.045 L)(0.10molL)=0.0045 mol base

Since the amount of base has exceeded the amount of acid, we can calculate the post-equivalence concentration of OH−.

[OH−]=nOH−V=(0.0045−0.0039) mol OH−(0.015+0.045) L[OH−]≈1.00×10^−2 M

pH=14.00+log(1.00×10^−2)=12.00

Since the hydroxide concentration is only precise to two significant figure, the logarithm should be rounded to two decimal places.

Time taken = 5 s

Average speed of box = ?

Solution:

s = d/t

s = speed

d = distance

t = time

by putting values,

s = 1.5 m/ 5 s

s = 0.30 m/s

Answer:

Option B. It is a basic solution.

Explanation:

To know which option is correct, let us calculate the pH of the solution.

First, we shall determine the pOH of the solution. This is illustrated below:

Concentration of Hydroxide ion, [OH¯] = 3.5×10¯⁶

pOH =.?

pOH = –Log [OH¯]

pOH = –Log 3.5×10¯⁶

pOH = 5.5

Finally, we shall determine the pH. This can be obtained as follow:

pOH = 5.5

pH =?

pH + pOH = 14

pH + 5.5 = 14

Collect like terms

pH = 14 – 5.5

pH = 8.5

The pH scale reads as follow:

0 to 6 => Acidic

7 => Neutral

8 to 14 => Basic

Comparing the pH of the solution (i.e 8.5) with the pH scale, we can conclude that the solution is basic because the pH of solution lies between 8 and 14.

In addition to carbon dioxide, water also includes other gases from the atmosphere. When the carbon dioxide dissolves, it produces carbonic acid, giving regular rain a pH of 5.6 on the pH scale.

Acid rain, also known as acid deposition, is any sort of precipitation that falls to the earth from the sky in wet or dry forms and contains acidic materials like sulfuric or nitric acid. This might include things like acidic dust, rain, snow, fog, and hail.

When sulfur dioxide (SO2) and nitrogen oxides (NOX) are released into the atmosphere and carried by wind and air currents, acid rain is the outcome. Nitric and sulfuric acids are created when the SO2 and NOX combine with water, oxygen, and other substances. Then, before hitting the ground, they combine with water and other substances.

pls mark me as brainlliest

Answer:An element which is highly conductive, highly reactive, soft, and lustrous is most likely an alkali metal.

Explanation:Alkali metals are in group 1 of the Periodic table which means that they have only a single valence electron.

This causes them to be soft and highly reactive because:

The single valance electron leads to weak bonds amongst the element's atoms which makes them soft

The elements want to lose the single valance electron so as to become stable so they will react with other elements to give away the electron.

Examples of alkali electrons include:

Lithium

Sodium

Potassium etc

In conclusion therefore, alkali metals are highly reactive and soft and so the element described above is most likely an alkali metal.
