Matter cannot be divided indefinitely is part of the:

Answer:

0.1 L

Explanation:

M₁ × V₁ = M₂ × V₂

10M × V₁ = 1M × 1L

V₁ = 0.1 L

I hope this helps :)

The molar dilution can be used to estimate the molarity or the volume. 0.1 L of 10 M solution is required to make 1 M of solution.

A dilution factor of the molar concentration is used to calculate the molar concentration or the volume needed to make the diluted solution from the stock.

Given,

M₁ = 10 M

V₁ = ?

M₂ = 1 M

V₂ = 1 L

The volume is calculated as:

M₁ V₁ = M₂ V₂

10 V = 1 × 1

V = 1 ÷ 10

= 0.1 L

Therefore, 0.1 L of the 10 M solution is needed.

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, there are total 18 electrons in the given compound.

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

C) the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product

Explanation:

The beta oxidation of fatty acids is the process by which long chain saturated and unsaturated fatty acids are oxidized to the two-carbon product, acetylCoA.

The beta oxudation of fatty acids occurs in four steps after which the chain length is shortened by 2 with cleavage of an acetylCoA molecule.

The first step involves the oxidation of the fatty acid with introduction of a double bond between C-2 and C-3 of the long carbon chain. This reaction produces FADH2 which donates its electrons to electron carriers in the electron transport chain tomproduce 1.5 moles of ATP. This is the case with saturated fatty acids.

However, in unsaturated fatty acids (which are less reduced than saturated fatty acids) where there is already a double bond innthe molecule, the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product.

This causes a reduction In the number of ATP produced by unsaturated fatty acids when compared to saturated fatty acids.

Answer:

3.22

Explanation:

The pOH is defined as:

pOH = - log [OH⁻]

From the problem, we have [OH⁻] = 6.0 x 10⁻⁴.

Thus, we introduce the concentration in the equation to calculate the pOH:

pOH = - log [OH⁻] = -log (6.0 x 10⁻⁴) = 3.22

Answer:

1.67 × 10⁻¹⁰m is the answer.

Explanation:

Given,

4 × 10⁻⁷m thick

2400 atoms thick

therefore 1 atom,

Diameter = 4 × 10⁻⁷/2400

d = 4000 × 10⁻¹⁰/2400

d = 1.67 × 10⁻¹⁰m

∴ diameter of 1 gold atom (3 significant figures) = 1.67 × 10⁻¹⁰m

The answer option which best explains the age of oceanic crust and ocean-floor features is: A. Seafloor spreading.

Earth crust refers to the outermost layer (thin shell) which makes up the Earth such as igneous, metamorphic, and sedimentary rocks.

Generally, the two (2) main types of Earth crust include:

An oceanic crust has a thickness ranging from 5 kilometers to 10 kilometers and it comprises denser rocks such as gabbro, diabase, and basalt.

Seafloor spreading can be defined as a process which involves the formation of new oceanic crust due to volcanic activity and an upwelling of magma at mid-ocean ridges, as well as a subsequent outward movement from the ridge.

Basically, the theory of seafloor spreading can be used to explain in details how a new oceanic crust is created or formed at mid-ocean ridges.

Hence, seafloor spreading best explains the age of oceanic crust and ocean-floor features.

[tex]workdone = force \times distance \\ W = (2.6 \times {10}^{ - 4} ) \times (3.7 \times {10}^{ - 3} ) \\ W = 9.62 \times {10}^{ - 7} \: joules[/tex]

The formula W = Fd, where W is the amount of work done, F is the force, and d is the distance, is used to determine how much work is done on a particle when it is pushed by a force. The force and distance in this issue are 2.6 10-4 newtons and 3.7 10-3 metres, respectively.

We add the force and distance together to determine the work done: 9.62 10-7 newton-meters are equal to W = 2.6 10-4 newtons x 3.7 10-3 metres. The response must be presented using the appropriate scientific notation and significant numbers.

The solution should include three significant figures, just like the numbers in the problem, which have three. Therefore, 9.62 10-7 newton-meters is the correct answer.

This response uses appropriate scientific language.notation because the exponent is a negative power of 10 and the coefficient ranges from 1 to 10. In conclusion, the particle underwent work from the force of 9.62 10-7 newton-meters. This response uses the appropriate scientific notation and the correct number of significant digits.

Explanation:

Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

Soil conservation can be defined as the use of various techniques so as to prevent the loss of the top most later of the soil and protecting it from degradation. Thus, the fertility of the soil is maintained.

Answer:

only god knows the answer

The Gibbs free energy is given by the change in enthalpy, temperature, and change in entropy. The standard change in Gibbs free energy for oxidation of iron is –1484.6 kJ.

Gibbs free energy is the energy present in a thermodynamic system that is used by the reactant to form a product. It is given as,

Δ G° = Δ H° -T ΔS°

The oxidation reaction of iron is given as,

4Fe(s) + 3O₂(g) → 2Fe₂O₃(s)

Given,

ΔS° = –549.73 J∙K⁻¹

T = 298 K

Δ H° = –824.2 kJ∙mol⁻¹

Substituting values above the Gibbs free energy is calculated as:

Δ G° = Δ H° -T ΔS°

= –824.2 kJ∙mol⁻¹ -  298 K ( –549.73 J∙K⁻¹)

= -1484580.46 J

The units of joules are converted into kilojoules and the standard change in Gibbs free energy will be –1484.6 kJ.

Therefore, –1484.6 kJ is the Gibbs free energy.
