what is the main difference between sexual and asexual reproduction

Answers

Answer:

Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information.

The main difference between sexual and asexual reproduction is that sexual reproduction involves the fusion of gametes, while asexual reproduction does not.

In sexual reproduction, offspring are produced through the fusion of gametes (reproductive cells) from two parent organisms. This fusion, known as fertilization, results in offspring that inherit genetic material from both parents. This genetic recombination introduces variation in the offspring, promoting genetic diversity within a population.

In contrast, asexual reproduction involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. A single parent organism reproduces by generating genetically identical or near-identical offspring through various methods such as budding, fragmentation, or binary fission. Asexual reproduction typically leads to offspring that are genetically identical to the parent, lacking the genetic diversity observed in sexual reproduction.

Consider the following chemical reaction.
3 Zn(C₂H₃O₂)₂(aq) + 2 Na₃PO₄(aq) → 6 NaC₂H₃O₂(aq) + Zn₃(PO₄)₂(s)

A chemist makes a solution of zinc acetate by dissolving 20.5 g Zn(C₂H₃O₂)₂ in 105 mL H₂O. What is the concentration of this zinc acetate solution?

Answers

The concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M

We'll begin by calculating the number of mole in 20.5 g of Zn(C₂H₃O₂)₂

Mass of Zn(C₂H₃O₂)₂ = 20.5 g

Molar mass of Zn(C₂H₃O₂)₂ = 65 + 2[(12×2) + (3×1) + (16×2)]

= 65 + 2[59]

= 183 g/mol

Mole of Zn(C₂H₃O₂)₂ =?

Mole = mass / molar mass

Mole of Zn(C₂H₃O₂)₂ = 20.5 / 183

Mole of Zn(C₂H₃O₂)₂ = 0.112 mole

Finally, we shall determine concentration of Zn(C₂H₃O₂). This can be obtained as follow:

Mole of Zn(C₂H₃O₂)₂ = 0.112 mole

Volume = 105 mL = 105 / 1000 = 0.105 L

Concentration of Zn(C₂H₃O₂)₂ =?

Concentration = mole / Volume

Concentration of Zn(C₂H₃O₂)₂ = 0.112 / 0.105

Concentration of Zn(C₂H₃O₂)₂ = 1.067 M

Therefore, the concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M

How many moles are present in 5.67x10^25 atoms of Carbon (C)?

Explanation:

Hope this helps! :^)

94. 125 moles are present in 5.67x10^25 atoms of Carbon (C).

What is mole?

The mole is a unit of measurement that is comparable to well-known units like pair, dozen, bulk, etc. It offers a precise count of atoms or molecules in a large sample of materials.

The amount of substance that has the same number of discrete entities (atoms, molecules, ions, etc.) as the number of atoms in a sample of pure 12C weighing exactly 12 g is known as a mole.

The word "mole" has a "big mass" or "bulk" sense in Latin, which is congruent with its use as the name for this unit. The mole establishes a connection between bulk mass, which is a simple macroscopic attribute to measure, and the number of atoms, molecules, and other fundamental units, which is a crucial fundamental property.

Therefore, 94. 125 moles are present in 5.67x10^25 atoms of Carbon

Calculate the solubility of copper (II) iodate in 0.16 M copper (II) nitrate. Ksp* is 7.4x10-8 M3. *You should know that the Ksp must refer to the copper iodate because all nitrate compounds are soluble and strong electrolytes!

Answers

Answer:

solubility in presence of 0.16M Cu(IO₃⁻)₂ = 3.4 x 10⁻⁴M*

Explanation:

        Cu(IO₃⁻)₂ ⇄           Cu⁺²          +   2(IO₃⁻)        

C(i)    ----------                0.16M                 0M

ΔC    ----------                   +x                   +2x

C(f)    ----------      0.16 + x ≅ 0.16M*        2x

Ksp = [Cu⁺²][IO₃⁻]²

7.4 x 10⁻⁸M³ = 0.16M(2x)² = 0.64x²

x = solubility in presence of 0.16M Cu(IO₃⁻)₂ = SqrRt(7.4x10⁻⁸M³/0.64M²)

= 3.4 x 10⁻⁴M*

*Note: This is consistent with the common ion effect in that a reduction in solubility is expected. The normal solubility of Cu(IO₃⁻)₂ in pure water at 25°C is ~2.7 x 10⁻³M.

the enthalpy of combustion of gasoline is about 45 kj/g. the amount of energy needed to heat 1 g of water from 20 °c to 100 °c is 80 °c x 4.18/g•°c. the enthalpy of vaporization of water is 2540 j/g. what mass of water at 20 °c can 1 g of gasoline heat and boil?

Answers

The mass of water that can be boiled by 1 g of gasoline by raising its temperature from 20 °c to 100 °c is  17.6 g.

Now, we know that energy can not be created nor destroyed but it can be converted from one form to another.

The heat produced by the gasoline is equal to the heat gained by water. Mathematically;

1g ×  45 × 10^3 = [1 g × 4.18  × (100 - 20) + 2540m]

45 × 10^3 = 334.4 + 2540m

45 × 10^3 - 334.4 =  2540m

m =  45 × 10^3 - 334.4 /2540

m = 17.6 g

The mass of water that can be boiled by 1 g of gasoline by raising its temperature from 20 °c to 100 °c is 17.6 g.

A 23.6 g sample of an unknown gas occupies a volume of 12.0 L at standard temperature and pressure. What is the molecular mass (molar mass) of this gas?

Answers

The molecular mass (molar mass) of this gas is equal to 44.08 g/mol.

Given the following data:

Mass = 23.6 gramsVolume = 12.0 LitersStandard temperature = 273 KStandard pressure = 1 atm.

To calculate the molecular mass (molar mass) of this gas, we would use the ideal gas law equation;

[tex]PV=\frac{MRT}{MM}[/tex]

Where;

P is the pressure.V is the volume.M is the mass of substance.MM is the molar mass of a substance.R is the ideal gas constant.T is the temperature.

Making MM the subject of formula, we have:

[tex]MM = \frac{MRT}{PV} \\\\MM = \frac{23.6\times 0.0821 \times 273}{1 \times 12}\\\\MM = \frac{528.95}{12}[/tex]

Molar mass, MM = 44.08 g/mol.

A sample of damp air in a 1.00 L container exerts a total pressure of 741.0 torr at 20 oC; but when it is cooled to -10 oC, the water vapor freezes to ice with neglegible pressure giving a pressure of 607.1 torr. How many molecules of water were present in the gas

Answers

From the information presented in the question, the number of molecules present of water present is obtained 2.41 × 10^21 molecules.

From the information we have;

Volume of the damp air =  1 L

Pressure of the damp air =  741.0 torr or 0.975 atm

Temperature of the gas = 20 oC + 273 = 293 K

R = 0.082 atm LK-1mol-1

Number of moles = ?

n =PV/RT

n = 0.975 × 1/0.082 ×  293

n = 0.041 moles

Volume of water vapor = 1 L

Temperature of water = -10 oC + 273 = 263 K

Pressure of the gas = 607.1 torr or 0.799 atm

R = 0.082 atm LK-1mol-1

n= PV/RT

n = 0.799 × 1/ 0.082 × 263

n = 0.037 moles

Number of moles of water = 0.041 moles -  0.037 moles = 0.004 moles

If 1 mole = 6.02 × 10^23 molecules

0.004 moles = 0.004 moles × 6.02 × 10^23 molecules/1 mole
