Answer 2

The wave which is having higher frequency is associated with higher energy. In the given wave, the part B is labelling the lowest energy sound.

What are sound waves ?

Sound waves are longitudinal mechanical waves passing through a medium. In a longitudinal wave the oscillation of particles is in a direction along the wave propagation.

A sound wave is composed of rarefactions and compressions. The area where, the particles have some separation with lower  pressure is called rarefactions.

The area of high pressure where, the oscillating particles are closely packed is called compression of the wave. As the frequency of the wave increases, its energy increases, Therefore, the less frequency part B represent lowest energy sound.

What causes a substance to be hydrophobic?

Answers

The hydrophobic effect is caused by nonpolar molecules clumping together. Large macromolecules can have hydrophobic sections, which will fold the molecule so they can be close to each other, away from water. Many amino acids in proteins are hydrophobic, helping the proteins obtain their complicated shapes. The hydrophobic effect extends to organisms, as many hydrophobic molecules on the surface of an organisms help them regulate the amount of water and nutrients in their systems.

Which group on the periodic table has the greatest number of metallic elements? O A. Group 18 (VIIIA) O B. Group 2 (IIA) OC. Group 13 (IIIA) O D. Group 7 (VIIB)​

Answers

Answer: 18

Explanation:

i took a test and reviewed it and it said 18

On the periodic table, group IA has the most metallic elements.

What is Periodic table?All identified chemical elements are arranged in rows (referred to as periods) and columns (referred to as groups) in the periodic table of chemical elements, also known as the periodic table, in ascending order of atomic number.Groups are the names given to the periodic table's columns. In the table, individuals who belong to the same group make bonds of the same kind and have an equal number of electrons in their atoms' outermost shells. The periods refer to the horizontal rows.Elements in the periodic table can be divided into groups and eras. The periodic table is organized into horizontal rows for periods and vertical columns for groupings. As you advance, the atomic number grows.

What volume of oxygen at 455 K and a pressure of 127400 Pa is produced by the decomposition of 114.7 g of BaO2 to BaO and O2?

Answers

Answer:

10 L

Explanation:

The equation of the reaction is;

2BaO2 = 2BaO + O2

Number of moles of  BaO2 = 114.7 g/169.33 g/mol = 0.677 moles

From the reaction equation;

2 moles of BaO2 yields 1 moles of O2

0.677 moles of BaO2 yields 0.677 * 1/2 = 0.3385 moles of oxygen

Hence;

PV=nRT

V = ?

P = 127400 Pa or 1.257 atm

T = 455 K

n = 0.3385 moles

R = 0.082 atmLmol-1K-1

V = nRT/P

V = 0.3385 * 0.082 * 455/1.257

V= 10 L

What is a galaxy?

A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity.The word is derived from the Greek galaxias , literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars,each orbiting its galaxy's center of mass.

Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies.

What is the coefficient in front of the O₂ when the equation below is balanced C₂H₆O₂(g) + O₂ (g) → CO₂(g) + H₂O (g)

Answers

Answer:

The balanced equation is:

2C₂H₆O₂ (g) + 5O₂ (g) → 4CO₂ (g) + 6H₂O (g)

Therefore, the coefficient in front of O₂ when the given equation is balanced is 5.

Explanation:

In order to balance a chemical equation, it is necessary to ensure that there is an equal number of atoms for each element on both sides of the equation. This can be achieved by adding coefficients to chemical symbols or formulas as required.

Given equation:

C₂H₆O₂ (g) + O₂ (g) → CO₂ (g) + H₂O (g)

This equation is not balanced, because there are:

2 carbon atoms on the left side of the equation and only one on the right side.6 hydrogen atoms on the left side of the equation and only 2 on the right side.4 oxygen atoms on the left side of the equation and only 3 on the right side.

Add the coefficient 2 in front of CO₂ and the coefficient 3 in front of H₂O on the right side of the equation:

C₂H₆O₂ (g) + O₂ (g) → 2CO₂ (g) + 3H₂O (g)

The carbon and hydrogen atoms are now balanced, but there are 4 oxygen atoms on the left side and 7 oxygen atoms on the right side. To balance the equation, double the coefficients on the right side and add the coefficient 2 in front of C₂H₆O₂ on the left side of the equation:

2C₂H₆O₂ (g) + O₂ (g) → 4CO₂ (g) + 6H₂O (g)

Now we have 6 oxygen atoms on the left side and 14 oxygen atoms on the right side.  So if we add the coefficient 5 in front of O₂, there are14 oxygen atoms on the left side, and thus the equation is balanced.:

2C₂H₆O₂ (g) + 5O₂ (g) → 4CO₂ (g) + 6H₂O (g)

[tex]\begin{array}{|l|c|c|}\cline{1-3}\vphantom{\dfrac12}&\sf Left\;side&\sf Right\;side\\\cline{1-3}\vphantom{\dfrac12}\sf Carbon&2 \times 2=4&4\\\cline{1-3}\vphantom{\dfrac12}\sf Hydrogen&2 \times 6=12&6 \times 2=12\\\cline{1-3}\vphantom{\dfrac12}\sf Oxygen& 2\times 2+5 \times 2=14&4 \times 2+6 =14\\\cline{1-3}\end{array}[/tex]

Therefore, the coefficient in front of O₂ when the given equation is balanced is 5.

3. Explain why ionic compounds are "fixed" in their chemical composition.

Answers

Answer: Ionic compounds are "fixed" in their chemical composition as forces present between atoms of these compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.

Explanation:

Compounds formed by transfer of electrons from one atom to another are called ionic compounds.

For example, sodium atom on losing its one valence electron forms [tex]Na^{+}[/tex] ion and when a chlorine atom gains this electrons then it forms [tex]Cl^{-}[/tex] ion. These ions when come closer then an electrostatic force of attraction will pull them together forming NaCl compound.

Therefore, one atom of sodium is chemically combining to one atom of chlorine to form NaCl.

As the forces present between atoms of an ionic compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.

Thus, we can conclude that ionic compounds are "fixed" in their chemical composition as forces present between atoms of these compound are strong electrostatic forces of attraction due to which these compounds have fixed chemical composition.

Ionic compounds are formed when there is a donation of an electron from one element to another that receives the electron. This causes the donating atom to attain a positive charge and the receiving atom to attain a negative charge. The ions thus formed are held by strong electrostatic forces that hold them together.

Ionic bonds are formed through the transfer of electrons from one element to another which receives the electron.

Positive and negative ionic charges are thus acquired by the respective elements. Strong electrostatic forces that act in all directions hold the ions together.

This also gives them the fixed state that makes it more difficult to break them up when compared to the covalent bonds.

So, the strong electrostatic forces cause the fixed state of ionic compounds.

25.2 g of CuSO4 6H20 (mm: 267.72 g/mol) is dissolved in 28.0 mL of water, calculate the molarity.

Answers

Answer:

3.36 M

Explanation:

Step 1: Given data

Mass of CuSO₄.6H₂O (m): 25.2 gMolar mass of CuSO₄.6H₂O (M): 267.72 g/molVolume of solution (V): 28.0 mL (we will assume it is equal to the volume of water)

Step 2: Calculate the moles (n) of CuSO₄.6H₂O (solute)

We will use the following expression.

n = m/M

n = 25.2 g / (267.72 g/mol) = 0.0941 mol

Step 3: Calculate the molarity

Molarity is equal to the moles of solute divided by the liters of solution.

M = 0.0941 mol/0.0280 L = 3.36 M
