Answer:

Brass

Explanation:

Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical and electrical properties.

Ionic bonds are formed between ionic compounds, Ionic compounds are formed when metals join with nonmetals.

Ionic bonds are electrostatic bonds that are formed between metals and nonmetals. It is an electrostatic attraction between oppositely charged ions in a chemical compound.

These bonds are formed when two or more atoms lose or gain electrons. An example of ionic bonds can be seen in the NaCl compound.

Na⁺ + Cl⁻ = Na⁺Cl⁻

NaCl is formed by the joining of oppositely charged elements. They constitute salt. Salt is made up of ionic compounds, so it easily dissociates into sodium and chloride when mixed in water.

Thus, ionic compounds are created when metals combine with nonmetals, and these combinations result in the formation of ionic bonds.

Answer:

Volume of HBr = V₂ =  7.5 mL

Explanation:

Given data:

Volume of NaOH =V₁= 25.0 mL

Molarity of NaOH =M₁= 0.150 M

Molarity of HBr =M₂= 0.5 M

Volume of HBr =V₂= ?

Solution:

M₁V₁    =      M₂V₂

0.150 M ×25.0 mL = 0.5 M×V₂

V₂ = 0.150 M ×25.0 mL  / 0.5 M

V₂ = 3.75 M.mL /0.5 M

V₂ =  7.5 mL

Answer:

The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells.

Explanation:

Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent. Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells.

Explanation:

Barium cannot ionically bond with Kalium. Kalium is the Latin name for potassium.

Both Barium and potassium are metals. Metals and Metals do not combine to form ionic compounds. Only metals and non-metals form this bond type.

Answer:

2.08L

Explanation:

V1 = 2.00L

P1 = 101kPa

P2 = 97.0kPa

V2 = ?

from Boyle's law,

P1V1 = P2V2

101 × 2 = 97 × V2

V2 = 202/97 = 2.08L

Therefore, the new volume is 2.08L

Answer:

2.1L

Explanation:

Given parameters:

Initial volume  = 2L

Initial pressure  = 101kPa

Final pressure  = 97kPa

Unknown:

Final or new volume  = ?

Solution:

Now to solve his problem which relates pressure and volume, we simply apply Boyle's law which is mathematically expressed below;

          P₁ V₁  = P₂ V₂

P and V are pressure and volume

1 and 2 are initial and final states;[tex]\frac{101 x 2}{97}[/tex]

         101 x 2  = 97 x V₂

              V₂  =  [tex]\frac{101 x 2}{97}[/tex]

Answer:

3.97 x 10²³atoms

Explanation:

Given parameters:

Mass of ammonia = 11.22g

Unknown:

Chemical amount of ammonia present  = ?

Solution:

The chemical amount present in a substance is the number of atoms it contains.

To solve this problem, from the given mass find the number of moles first.

  Number of moles  = [tex]\frac{mass}{molar mass}[/tex]

Molar mass of NH₃   = 14 + 3(1) = 17g/mol

  Number of moles  = [tex]\frac{11.22}{17}[/tex]   = 0.66mole

   1 mole of any substance contains  6.02 x 10²³ atoms

  0.66 mole of ammonia will contain 0.66 x 6.02 x 10²³ atoms

                                                            = 3.97 x 10²³atoms

Answer:

Energy from different sources leads to different types of rocks.

Explanation: Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into different types of rock.

Rocks are formed in earth by the deposition of minerals and decomposition of massive tectonic plates by the hot magma which is melted by the heat energy radiated from sun.

There are broadly three different types of rocks, namely sedimentary rocks, igneous rocks and metamorphic rocks . They are classified based on their formation and composition.

The magma that the molten mineral fluid inside the earth crest melts under heat radiated from sun and this hotter fluid flows results in movement of tectonic plates and decomposition at some places.

Therefore, the heat energy and resultant convection current leads the tectonic plate boundaries and formation of different kinds of rocks which are stimulated by the action of air and water.

Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, the wavelength of light is 2.41×10⁻⁷m.

Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave, light wave.

There is a relation between frequency of wave, and wavelength of wave

Mathematically,

ν=c÷λ

where,

ν=frequency of light=1.24 x10¹⁵s⁻¹

c is speed of light that is 3×10⁸m/s

λ is the wavelength of light=?

Substituting all the values

1.24 x10¹⁵s⁻¹=3×10⁸m/s÷λ

λ= 2.41×10⁻⁷m

Therefore, the wavelength of light is 2.41×10⁻⁷m.
