what is the longest-wavelength line in nanometers in the infrared series for hydrogen where m = 3?

Answers

Answer 1

The longest-wavelength line in the infrared series for hydrogen where m = 3 is known as the Paschen series.

The Paschen series corresponds to the transitions where the electron moves from a higher energy level to the third energy level (n=3). The formula for calculating the wavelength of a line in the Paschen series is given by  λ = 1.096776 × 10^-2 (1/3^2 - 1/m^2) meters. To convert this to nanometers, we can multiply by 10^9. When m=4, the longest-wavelength line in the Paschen series is 1093.33 nanometers.

Therefore, the answer to the question is that the longest-wavelength line in nanometers in the infrared series for hydrogen where m = 3 is not defined since the Paschen series begins at m = 4.

Describe the similarities and/or differences between heating and burning the magnesium metal. Did either heating or burning produce a chemical change?

Answers

Answer and Explanation:

Heating the magnesium metal is a physical change because after the process, the magnesium metal is still magnesium metal and no other substance is formed. When we heat the metal, we tranfer energy and the temperature is raised. It could include the melting of the metal, which is a change in the state of matter, but it is still a physical change because no chemical reactions occur.

Burning the magnesium metal is a chemical change because it involves the reaction with O₂ to form a different compound (a magnesium oxide).

. How many grams of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide? ____Cl2 + ____MgBr2  ___MgCl2 + ___Br2

Answers

Answer: 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide.

Explanation:

The balanced chemical reaction is;

[tex]Cl_2+MgBr_2\rightarrow MgCl_2+Br_2[/tex]

[tex]Cl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]MgBr_2[/tex] is the excess reagent.

According to stoichiometry :

1 mole of [tex]Cl_2[/tex] produces = 1 mole of [tex]MgCl_2[/tex]

Thus 2 moles of [tex]Cl_2[/tex] will produce=[tex]\frac{1}{1}\times 2=2moles[/tex]  of [tex]MgCl_2[/tex]

 Mass of [tex]MgCl_2=moles\times {\text {Molar mass}}=2moles\times 95g/mol=190g[/tex]

Thus 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide

explain the factor of a skeleton system ​

Answers

The human skeletal system consists of all of the bones, cartilage, tendons, and ligaments in the body. Altogether, the skeleton makes up about 20 percent of a person’s body weight. An adult’s skeleton contains 206 bones. Children’s skeletons actually contain more bones because some of them, including those of the skull, fuse together as they grow up. There are also some differences in the male and female skeleton. The male skeleton is usually longer and has a high bone mass. The female skeleton, on the other hand, has a broader pelvis to accommodate for pregnancy and child birth. Regardless of age or sex, the skeletal system can be broken down into two parts, known as the axial skeleton and the appendicular skeleton. Axial skeleton anatomyThe adult axial skeleton consists of 80 bones. It’s made up of the bones that form the vertical axis of the body, such as the bones of the head, neck, chest, and spine. The adult skull comprises 22 bones. These bones can be further classified by location: Cranial bones. The eight cranial bones form the bulk of your skull. They help to protect your brain. Facial bones. There are 14 facial bones. They’re found on the front of the skull and make up the face.Auditory ossicles The auditory ossicles are six small bones found within the inner ear canal in the skull. There are three auditory ossicles on each side of the head, known as the: malleus (hammer)incus (anvil)stapes (stirrup)They work together to transmit sound waves from the surrounding environment to the structures of the inner ear. The hyoid is a U-shaped bone found at the base of the jaw. It serves as a point of attachment for muscles and ligaments in the neck. The vertebral column is made up 26 bones. The first 24 are all vertebrae, followed by the sacrum and coccyx (tailbone). The 24 vertebrae can be further divided into the Cervical vertebrae. These seven bones are found in the head and neck. Thoracic vertebrae. These 12 bones are found in the upper back. Lumbar vertebrae. These five bones are found in the lower back. The sacrum and coccyx are both made up of several fused vertebrae. They help support the weight of the body while sitting. They also serve as attachment points for various ligament. The thoracic cage is made up of the sternum (breastbone) and 12 pairs of ribs. These bones form a protective cage around the organs of the upper torso, including the heart and lungs. Some of the ribs attach directly to the sternum, while others are linked to the sternum via cartilage. Some have no attachment point and are referred to as “floating ribs.”
There’s a lot of bones and bones

Soil horizon contains different layers of soil which are classified based on the composition of the soil and the presence of rocks within the soil. The primary level of the soil is rich in humus. The decomposed of matter of plants and animals are called humus. On which the plants are growing.

The secondary level of soil horizon or the subsoil level contains some small rocks also onto which the roots of plants does not adhere so much. The third level of soil horizon contains bigger rocks with small gaps between them.

The last layer of the soil horizon is called bedrock layer containing bigger rocks with no significant gaps between them It is called the bedrock layer.

If the point of the nail can be approximated as a circle with a radius 2.00×10^-3m What is the pressure in MPa exerted on the wall if a hammer strikes the nail with a force of 104 N

Answers

Answer:

8.28 MPa

Explanation:

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

Radius (r) = 2×10¯³ m

Force applied (F) = 104 N

Pressure (P) =?

Next, we shall determine the area of the nail (i.e circle). This can be obtained as follow:

Radius (r) = 2×10¯³ m

Area (A) of circle =?

Pi (π) = 3.14

A = πr²

A = 3.14 × (2×10¯³)²

A = 3.14 × 4×10¯⁶

A = 1.256×10¯⁵ m²

Next, we shall determine the pressure. This can be obtained as follow:

Force applied (F) = 104 N

Area (A) = 1.256×10¯⁵ m²

Pressure (P) =?

P = F / A

P = 104 / 1.256×10¯⁵

P = 8280254.78 Nm¯²

Finally, we shall convert 8280254.78 Nm¯² to MPa. This can be obtained as follow:

1 Nm¯² = 1×10¯⁶ MPa

Therefore,

8280254.78 Nm¯² = 8280254.78 Nm¯² × 1×10¯⁶ MPa / 1 Nm¯²

8280254.78 Nm¯² = 8.28 MPa

Thus, the pressure exerted on the wall is 8.28 MPa

Answer:

Decomposition Reaction

Explanation:

You can determine the type of reaction by writing out a balanced equation.

Solid Potassium Chlorate: KClO3

Potassium Chloride: KCl

Oxygen Gas: O2

Balanced Equation: 2KClO3 -> 2KCl + 3O2

By definition, a decomposition reaction is when a single substance decomposes into two more simpler substances. AB -> A + B

Because the solid potassium chlorate is breaking into two substances, potassium chloride and oxygen gas, it is a decomposition reaction.
