Please help me answer this question.

Answer:

ANIMAL CELL

Animal cells are generally small in size.

They don't have a cell wall

Except the protozoan Euglena, no animal cell possesses plastids.

Vacuoles in animal cells are many, small and temporary.

Animal cells have a single highly complex and prominent Golgi apparatus.

Animal cells have centrosome and centrioles.

PLANT CELL

Plant cells are larger than animal cells.

The plasma membrane of plant cells is surrounded by a rigid cell wall of cellulose.

They have Plastids

Most mature plant cells have a permanent and large central sap vacuole.

Plant cells have many simpler units of Golgi apparatus, called dictyosomes.

Plant cells lack centrosome and centrioles.

Explanation:

There are two chlorine band six oxygen atoms in Zn ( ClO₃ )₂ molecule. Therefore, option A is correct.

With an atomic mass of 35.45 and an atomic number of 17, chlorine has an average of 17 protons, 17 electrons, and 18 neutrons in each of its atoms. Chlorine, which belongs to the halogen family on the Periodic Table, reacts vigorously with metals to produce salts.

Numerous industrial applications exist for chlorine as well. Including the production of plastics like PVC, solvents like tetrachloromethane, chloroform, and dichloromethane, as well as bulk goods like bleached paper products. In addition, it is utilized in the production of paints, textile colors, antiseptics, and pharmaceuticals.

Chlorine is a negative ion because it has a charge of 1, 1 more than protons. Atoms acquire or lose electrons during the formation of ions until their outer energy level is reached.

Thus, option A is correct.

Answer:

No-till conservation tillage

Explanation:

No till conservation involves the soil not being touched which gives rise to a large amount of organic matter being left on the surface.

The Advantage of this method is that it helps to prevent erosion such as that of wind and water due to the little or no exposure of the soil surface and helps to provide nutrients to the plants through the organic matter present.

The Disadvantage of this method is its heavy reliance of chemicals such as herbicides in killing the weeds in order to prevent competition for vital compounds with the main plants.

Answer:

Molecular formula = SF₆

Empirical formula is SF₆

Explanation:

Percentage of sulfur = 21.95%

Percentage of fluorine = 78.03%

Molar mass of compound = 146.1 g/mol

Empirical formula = ?

Molecular formula = ?

Solution:

Number of gram atoms of S = 21.95 / 32= 0.69

Number of gram atoms of F = 78.03 / 19 =  4.107

Atomic ratio:

                                  S                  :         F

                                0.69/0.69      :       4.107/0.69

                                     1                :         6

S : F =  1:6

Empirical formula is SF₆

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass :

32 + 19×6 = 146

n = 146.1 / 146

n = 1

Molecular formula = n (empirical formula)

Molecular formula = 1 (SF₆)

Molecular formula = SF₆

Answer:

6 moles of SO₃ formed.

Explanation:

Given data:

Number of moles of SO₃ formed = ?

Number of moles of oxygen react = 3 mol

Solution:

Chemical equation;

2SO₂+ O₂      →   2SO₃

now we will compare the moles of oxygen and sulfur trioxide.

                             O₂            :            SO₃

                               1             :             2

                               3            :           2/1×3 = 6 moles

Thus, six moles of SO₃ will formed.

Answer:

The correct answer is - cellular respiration is when chemical energy from sugar/glucose is converted to cellular energy in the form of ATP.

Explanation:

Cellular respiration is a set of metbolic reaction that takes place inside the cell and breaking the sugars or nutrients to convert the chemical energy present in the nutrients into the cellular energy whic is used by cells that is ATP and release water and carbon dioxide as waste.

In this process the ammount of energy store in the cellular currecncy or ATP which is the form of energy that is utilized by the to perform its sunction. The chemical energy that is present in the nutrients or sugar is come from light energy which is stored in the nutrients by photosyntheis process.

Answer:

Oxygen

Explanation:

Cellular respiration is the metabolic process that involves the breakdown of glucose molecule in order to synthesize energy in form of ATP. However, this cellular respiration can either be aerobic or anaerobic depending on whether oxygen is used or not.

Aerobic cellular respiration is the respiration that involves the use of OXYGEN. It occurs in the mitochondria of the cell, where oxygen is used as the final electron acceptor. Hence, according to the question, OXYGEN is used up during cellular respiration.

Answer:

c actual contains three atom

Answer:

99.90g

Explanation:

1.506 x 10^24atoms × [tex]\frac{1mol}{6.022*10^{23}atoms}[/tex] × [tex]\frac{39.948grams}{1mol}[/tex] = 99.90grams

multiply the atom by constant and by its molar mass

1.506 x 10²⁴ atoms of argons gas is two moles. One mole of argon weighs 35.9 g. Thus mass of two moles of argon is 89.9 g.

Argon is 18th element in periodic table. It is placed in 18 the group and it is a noble gas or inert gas with completely filled orbitals. The group members of argon are neon, krypton, xenon and radon.

One mole of every substance contains 6.022 × 10²³ atoms. This number is called Avogadro number. Therefore, one mole of every element contains Avogadro number of atoms. The atomic mass of an element is the mass of one mole of that element.

Mass of one mole of argon is 35.9 g. Thus, it contains  6.022 × 10²³ atoms. Hence, the number of moles that contains  1.506 x 10²⁴ atoms is calculated as follows:

no.of moles =  1.506 x 10²⁴  / 6.022 × 10²³

                    = 2.5 moles.

The mass of 2.5 moles of argon is 2.5 × 35.9 = 89.9 g. Hence, the mass of  1.506 x 10²⁴ argon atoms is 89.9 g.
