Explanation:

Given data:

Wavelength of radiation = 5.00 × 10⁻⁸ m

Frequency of radiation = ?

Solution:

Formula:

Speed of light = wavelength × frequency

speed of light = 3 × 10⁸m/s

Now we will put he values in formula.

3 × 10⁸m/s = 5.00 × 10⁻⁸ m ×  f

f = 3 × 10⁸m/s / 5.00 × 10⁻⁸ m

f = 0.6× 10¹⁶ s⁻¹

s⁻¹ = Hz

f = 0.6× 10¹⁶ Hz

Explanation:

Copper (I) sulfide is formed by the chemical reaction between copper and sulfur. Copper is a limiting reagent that results in the formation of 190.26 grams of copper(I) sulfide.

A limiting reagent is defined as the reactant that gets completely utilized in the reaction and affects the amount of the product formation. On the contrary, the excess reagent is present in more amounts.

Given,

Mass of copper = 127 gm

Mass of sulfur = 41 gm

Moles of copper:

n = mass ÷ molar mass

n = 127 ÷ 63.546

n = 1.99

Moles of sulfur:

n = 41 ÷ 32.065

n = 1.27

The reaction is shown as:

Cu + S → CuS

Here, 9 g of sulfur remains unreacted and hence is an excess reagent, and copper being consumed is a limiting reagent.

Here, 1 mole of copper reacts to form 1 mole of copper sulfide hence, 1.99 moles of Cu produces, 1.99 moles of copper sulfide.

Mass of CuS is calculated as:

Mass = moles × molar mass

Mass = 1.99 mol × 95.611 g/mol

= 190.26 grams

Therefore, 127 gm of copper and 41 gm of sulfur produces 190.26 grams of copper sulfide.

Explanation:

An acid (A) will have acid in the name.  It will also have a hydrogen bonded to an electronegative compound.  A molecular compound (M) will have nonmetals and/or hydrogen.  An ionic compound (I) will have nonmetals and first and second column metals.  It could also include charged compounds.  A transition metal (TM) will have a transition metal in the compound.

The formulas for TM and I are made by balancing the charges of the atoms to equal zero.  The formulas for M can be found from the name itself.  The formulas for A have to be memorized.

TM  ==>  copper (II) oxide  ==>  CuO

A  ==>  hydrosulfuric acid  ==>  H₂S

TM  ==>  iron (III) fluoride  ==>  FeF₃

TM  ==>  lead (II) chlorate  ==>  PbCl₂

A  ==>  hydrochloric acid  ==> HCl

M  ==> dihydrogen monoxide  ==>  H₂O

A  ==>  sulfurous acid  ==>  H₂SO₃

I  ==>  potassium oxide  ==>  KO

I ==>  ammonium hydroxide  ==>  NH₄OH

M  ==> nitrogen trioxide  ==>  NO₃

I  ==>  aluminum phosphate  ==>  AlPO₄

To name ionic (I) compounds, simply put the name of the metal with the nonmetal.  But, for the nonmetal change, the ending to "-ide".  To name acids (A), say hydro- with the atom/compound it is attached to and end with acid.

I  ==>  MgSO₄  ==>  magnesium sulfate

I  ==>  HgS  ==>  mercury sulfide

I  ==>  Na₂S  ==>  sodium sulfide

A  ==>  HF  ==>  hydrofluoric acid

I  ==>  KCN  ==>  potassium cyanide

Less soil erosion

Explanation:

Due to the low amount of rainfall in this region, it is easier to say that the region compared to other ecoregion will suffer less soil erosion.

Erosion is usually the washing away of the top layer of the soil. Rainfall is one of the most important element that causes erosion. Surface runoff for an extended period of time can remove the topmost layer of the earth on which plant can grow. This starves the soil of its rich nutrients and minerals.

Answer:

At least four glucose residues separate α‑1,6 linkages.

The number of sites for enzyme action on a glycogen molecule is increased through α‑1,6 linkages.

The reaction that forms α-1,6 linkages is catalyzed by a branching enzyme.

Explanation:

Glycogen is a polymer of glucose and is the primary carbohydrate storage form in animals. The polymer is composed of glucose units linked in alpha(1-4) straight chains and alpha(1-6) branches which occur on average every 8-12 straight chain glucose residues. It has a reducing and non-reducing end. The end of the molecule containing a free carbon number one on glucose is called a reducing end. The other ends are all called non-reducing ends.

During the breakdown of glycogen, glucose units are removed one at a time from the non-reducing end until a point about four glucose residues away from a branch which will require a debranching enzyme to act for further breakdown to occur. Since many such branches occur in a glycogen molecule, it makes it possible for breakdown of glycogen to occur at many points speedily.

Glycogen branching enzyme is required to make alpha (1-6) glycosidic bonds. It transfers 6 to 7 glucose units from the non-reducing end of a straight chain glycogen molecule to an interior position of the same or another glycogen molecule forming alpha (1-6) bonds.

Explanation:

Synthetic fiber or synthetic fibre (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). There are two types of polymerization: linear polymerization and cross-linked polymerization.

Synthetic material are madeup of monomers and long chain of monomers are known as polymers. The process is known as polymerization and the synthetic material are turned as microplastic which takes a long period of time to decompose. By this way the synthetic materials are very harmful for the society.

Answer:

53.4%

Explanation:

N₂ + 3H₂ → 2NH₃

Given that:

26.3 g of H₂ react with N₂ to produce 79.0 g of NH₃

Then:

The number of moles of H₂ = 26.3g of H₂ * (1 mol of H₂/ 2.02g of H₂)

= 13.05 mol of H₂

The number of moles of NH₃ = 13.05 mol of H₂ * ( 2mol of NH₃/ 3 mol of H₂)

= 8.697 mol of NH₃

The mass of NH₃ = 8.697 mol of NH₃ *( 17.04g of NH₃/ 1 mol of NH₃) = 148.1 g of NH₃

The percent yield = actual yield/ theoretical yield * 100%

The percent yield = ( 79.0 g/ 148.1 g )* 100%

The percent yield ≅ 53.4 %

Explanation:

Given data:

Mass of calcium chlorate = 13.8 g

Mass of oxygen produced = ?

Solution:

Chemical equation:

Ca(ClO₃)₂        →      CaCl₂ + 3O₂

Number of moles of calcium chlorate:

Number of moles = mass / molar mass

Number of moles = 13.8 g/ 206.98 g/mol

Number of moles = 0.07 mol

Now we will compare the moles of oxygen and  calcium chlorate.

                 Ca(ClO₃)₂         :            O₂

                      1                   :              3

                    0.07               :            3×0.07=0.21 mol

Mass of oxygen:

Mass = number of moles × molar mass

Mass = 0.21 mol × 32 g/mol

Mass = 6.72 g
