The second temperature of the sample of gas is 24.3°C

The calculation can be done as follows

T1= 27 °c

T2= ?

V1= 10 dm

V2= 9 dm

V1/T1= V2/T2

10/27= 9/T2

Cross multiply

10 ×T2= 9 × 27

T2= 9 × 27/10

= 243/10

= 24.3 °C

Hence the second temperature is 24.3°C

In miles per hour, the speed of light (which is 300,000 km/s), is equal to 67,10,70,000 miles/hr.

Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye

Given the speed of light in kilometers per second (km/s) -

300,000 km/s.

To convert the speed from kilometers per second (km/s) to miles per hour (miles/hr), we should know the relationship between 1 km/s and 1 mile/hr. The light moves at 300,000 km/s.

Now -

In 1 km/s = 2,236.9 miles/hr

Therefore -

in 300,000 km/s = 300,000 km/s x 2236.9 = 67,10,70,000 miles/hr.

Therefore, in miles per hour, the speed of light (which is 300,000 km/s), is equal to 67,10,70,000 miles/hr.

When the equation for the reaction representation above is balanced and all coefficients are reduced to the lowest whole-number terms, the coefficient for O₂ is 5.

An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and total charge for each component of the reaction. In other words, both sides of the reaction have an equal balance of mass and charge.

Note that a chemical equation that is balanced has equal amounts of each element's atoms on both sides of the equation and conserves mass.

Based on the equation given  O₂ will have 5unit or mole if it is balanced because the  C₃ will share with O₂.

An umbrella is placed in a drink holding a volume of punch equal to 7 mL. The height of the punch rose to 10 mL. If the mass of the umbrella was 27 g, the Density of the umbrella is 9 g/mL.

Given that :

The mass of the umbrella = 27 g

The volume of the umbrella :

= height of the punch rose - volume of the punch

= 10 mL - 7 mL

= 3 mL

The density of the umbrella is give as :

Density = mass / volume

Density = 27 g / 3 mL

Density = 9 g/mL

The name of the ionic compound made of beryllium and chlorine is Beryllium chloride (option D).

Ionic compounds are compounds that are made up of oppositely charged ions. These ions are formed by transferring electrons from one atom to another. They are made up of cations and anions. Cations are positively charged ions, whereas anions are negatively charged ions.

The formation of ionic compounds involves the transfer of electrons from the metal to the non-metal. This creates oppositely charged ions that are attracted to each other, forming the ionic bond between them.

The formula for an ionic compound represents the ratio of cations to anions in the compound.

Examples of ionic compounds are sodium chloride (NaCl), magnesium oxide (MgO), and calcium chloride (CaCl2).

Thus, the correct answer is option D, beryllium chloride.

The chemical structure of ammonia (NH3) has polar bonds, trigonal pyramidal shape, and it is a polar molecule.

In ammonia (NH3), the nitrogen atom is more electronegative than hydrogen. As a result, the nitrogen-hydrogen bonds are polar, with nitrogen having a partial negative charge (δ-) and each hydrogen has a partial positive charge (δ+).

It has a pyramidal molecular shape. The lone pair of electrons on the nitrogen atom pushes the three hydrogen atoms away from it, resulting in a trigonal pyramidal geometry. Ammonia (NH3) is a polar molecule due to the presence of polar bonds and its asymmetric shape.

A substance has the chemical structure C4H9N. Compound is a saturated acyclic hydrocarbon if the index of hydrogen shortage is zero.

If everything went according to plan, you would have discovered that IHD = 4, which denotes a total of 4 rings and/or pi bonds. Pi bonds can form between two carbons (C=C, CC), two carbons and oxygen (C=O), two carbons and nitrogen (C=N, CN), two nitrogens (N=N), or two oxygen atoms (N=O). Any rings may or may not contain the N or O.

Explanation:

In the crossing over the phenotypes of their children, 50% are widow's peak (aa), while 50% are not widow's peak (Aa) because the widow's peak genes only show trait when it is in recessive condition.

An inheritance pattern known as autosomal recessive inheritance allows a genetic disease or characteristic to be transferred from parent to offspring.

When a kid receives one altered (mutated) gene from each parent, a genetic disease may result. An autosomal recessive disorder is typically not present in the parents of a kid who has it.

EXPLANATION

Firstly, we need to define the word titration.

Titration is defined as a technique that is used to determine the known concentration of an unknown solution.

This normally occurs between an acid and a base

During titration, an indicator changes color when equilibrium has been attained between the two solutions. The solutions are normally acid and base. At equilibrium, the number of moles of acid is equal to the number of base.

Therefore, the correct answer is option C

The mole fraction of \(CH_3OH\)in the solution is 0.850 or 85.0%.

To calculate the mole fraction (Χ) of methanol (CH3OH) in the given solution, we need to determine the number of moles of CH3OH and the number of moles of \(C_6H_5COOH\)(benzoic acid) in the solution.

First, we can calculate the number of moles of CH3OH using its volume and density:

Mass of CH3OH = Volume x Density = 8.50 mL x 0.792 g/mL = 6.732 g

Number of moles of CH3OH = Mass / Molar mass = 6.732 g / 32.04 g/mol = 0.210 mol

Next, we can calculate the number of moles of \(C_6H_5COOH\)using its mass and molar mass:

Number of moles of C6H5COOH = Mass / Molar mass = 4.53 g / 122.12 g/mol = 0.0371 mol

The total number of moles of solute in the solution is the sum of the moles of CH3OH and C6H5COOH:

Total number of moles = 0.210 mol + 0.0371 mol = 0.247 mol

Finally, we can calculate the mole fraction of \(CH_3OH\)using its number of moles and the total number of moles:

Mole fraction of \(CH_3OH\)= Number of moles of \(CH_3OH\)/ Total number of moles = 0.210 mol / 0.247 mol = 0.850

During laboratory work to separate \(Ca^2^+\) and \(Cu^2^+\) ions in aqueous solution, certain chemicals may be used to preferentially precipitate one of the ions. \(Ca^2^+\) ions can be precipitated into calcium sulfate \((CaSO_4)\)using \(K_2SO_4\). Similar to \(K_2S\), \(Cu^2^+\) ions can be precipitated as copper sulfide (CuS) using \(K_2S\).

Solubility mismatches between the precipitates produced and the residual ions in solution are what drive these precipitation reactions. \(Ca^2^+\) and \(Cu^2^+\) ions cannot be dissociated by KI.
