The reaction, Fe2O3 + 3CO------> 2Fe + 3CO2 is an oxidation-reduction reaction.

An oxidation-reduction reaction is a reaction in which there is a change in oxidation number from left to right in the reaction. This is because, a specie is oxidized and another specie is reduced.

In the reaction;  Fe2O3 + 3CO------> 2Fe + 3CO2, we can see that the oxidation number of iron decreased from +3 on the left hand side to zero on the right hand side. The oxidation number of carbon was increased from + 2 to +4.

CELLULAR RESPIRATION:

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.

The equation for cellular respiration is as follows:

Why does a solid fill only part of a closed jar while the same mass of a gas fills the whole jar?

Answers

Answer:

because of atom don't put that as an answer

Explanation:

i need point to do finals

The different behavior of particles in solids and gases, including the intermolecular forces and kinetic energy, leads to solids filling only part of a closed jar while the same mass of a gas fills the whole jar. A solid fills only part of a closed jar, while the same mass of a gas fills the whole jar due to the differences in the behavior of particles in each state of matter.

1. Solid: In a solid, the particles are tightly packed and held in a fixed position. They have a definite shape and volume. The intermolecular forces between the particles are strong, preventing them from moving freely. As a result, solids occupy a specific amount of space within a container.

2. Gas: In a gas, the particles are spread out and move freely. They have no definite shape or volume. The intermolecular forces between the particles are weak, allowing them to move and fill the available space. As a result, gases can expand to fill the entire volume of a container.

When the same mass of a gas and a solid are placed in a closed jar, the gas particles have higher kinetic energy and are more mobile. They collide with each other and the walls of the container, exerting pressure and spreading out to occupy the entire space. Since the intermolecular forces are weak, the gas particles are not constrained by a fixed arrangement.

They may be the same substance even though they have different volumes and masses.

Intensive properties are the properties are characteristic  a substance. Intensive properties are those properties of a substance that can be used to describe the substance.

We can see that the substances have similar reactivity and similar density. This means that they may be the same substance even though they have different volumes and masses.

Would you expect the shielding effect to be greater in bromine than in chlorine?
A. Yes, because there are more filled orbitals in bromine.
B. Yes, because bromine has a higher atomic number.
C. No, because they are both in the same family.
D. No, because chlorine has a higher electronegativity than bromine.

Answers

The shielding effect of bromine is greater than chlorine because there are more filled orbitals than in chlorine.

Shielding Effect

This is the process where by electrons are protected by the pull attraction of the nucleus with the use of electron shells. The shielding effect increases down the group of the periodic table and increases across the period. This is because when you move down the group, there's an increase in the number of shell by 1 and it helps to reduce the effect of nuclear attraction on the electrons. However when you move across the period, there's an increase in the numbers of electron with the same shielding electrons from group 1(a) across the period to group 7(a).

Factor that affect the shielding effect of an electronThe numbers of electrons on the inner shells.Type of orbital which the electron is located.

Shielding effect is primarily dependent on the numbers of electrons in the inner shells as well as the type orbitals.

how would you expect the solubility of barium sulfate in pure water to compare to its solubility in 0.10 m nacl

Answers

Answer:

barium sulfate is insoluble (unable to dissolve) in water.

the general equation for the reaction between solid barium sulfate and nacl solution is this:

BaSO4 (s) + 2NaCl (aq) --> BaCl (aq) + Na2SO4 (aq)

to sum this up, to compare the solubility,

1. barium sulfate cant dissolve in pure water.

2. barium sulfate dissolves in nacl solution to give aqueous (aq) barium chloride (bacl) and aqueous sodium sulfate (na2so4), as shown in the equation above.

good luck!

The solubility of barium sulfate in pure water to zero as compare to the solubility in NaCl solution.

What is solubility?

Solubility is a property of any substance that defines how easily can be any substance will get dissolved or show dissolution.

Barium sulphate is insoluble in water beacuse it has higher lattice energy as well as higher size of cations & anions as compare to water, due to which water is not able to attract these ions towards itself affectively.Barium sulphate is soluble in the NaCl solution as this solution having ions which have more power to attract the ions of barium sulphate and show dissolution. Chemical reaction for this will be represented as:

         BaSO₄ (s) + 2NaCl (aq) → BaCl (aq) + Na₂SO₄ (aq)

Hence, barium sulphate is insoluble in water.

If 48.3g of iron is completely rusted in oxygen to produce 62.5g of iron (III) oxide, how many grams of oxygen are involved in the reaction?

Answers

The amount of oxygen involved in the reaction would be 20.7 g

The equation of rusting of iron is as follows:

[tex]4Fe + 3O_2 ---> 2Fe_2O_3[/tex]

The mole ratio of Fe to O2 is 4:3.

Mole of 48.3 g Fe = mass/molar mass

                               = 48.3/56

                                = 0.8625 moles

Equivalent mole of O2 = 0.8625 x 3/4

                                       = 0.6469 moles

Mass of 0.6469 moles O2 = mole x molar mass

                                             = 0.6469 x 32

                                              = 20.7 g
