Answers

Answer 1

Answer:

144 boxes, 72,000 washers

Explanation:

I'm not sure if this is right but convert the 18kg to g and then divide it by the grams. You get 144 and then multiply it by 500 for the total number of washers

Which is the state of matter shown in this figure ?

Answers

Answer:

It looks like a solid because they are densely packed kind of like an ice cube

Explanation:

The state of matter shown in this figure is solid state, because the particles are arranged densely in the form of cube.

What is solid state ?

The state of matter known as a solid has a definite form, mass, and volume. Changing the temperature causes extremely little variations in volume to be seen. For instance, sand, wood, copper, ice, etc., cannot be crushed.

One of the three fundamental states of matter, along with liquid and gas. Since atoms' energy drops when they adopt a comparatively organized, three-dimensional structure, solids can emerge from liquids or gases.

Because solids have specific mass, volume, and form, their component particles are arranged compactly. Between molecules, there is little intermolecular space. As a result, there is a strong force between the constituent particles (atoms, molecules, or ions).

Thus, option A is correct.

.What threatens the newly hatched chicks?

Answers

Answer:

rats. that's all i know of Just about everything except the mother hen if they are natural hatch. Even when you incubate them there are threats. The healthy chicks will mob the weak ones, the older chicks (even by a day) will pick on the younger ones. Temperature extremes will threaten them as they need warm, humid conditions with gradual drops in surrounding temps in the brooder box. Early disease is sometimes a problem and all chicks should be started on medicated chick feed for the first few weeks to prevent several digestive diseases. Even the water dispenser can be a threat as newly hatched chicks will immerse themselves in an open water container so care should be taken to supply water in a self feeding covered dish.

please help timed !! due rn !! What happens to particle motion as two substances come to thermal equilibrium?

Answers

Answer:

When two substances that are of different temperatures are brought together and there is heat transfer such that the substances come to thermal equilibrium, the effect on the particle motion are as follows

1) The particle motion of the hotter body reduces, because its temperature reduces

2) The particle motion of the colder body increases, because its temperature increases

3) For gases, the volume and or pressure reduces for the hotter body, and if the temperature of the gas falls below the boiling point temperature, the gas will change into liquid

For the colder gas, only the volume and or pressure increases and the temperature rises

4) For liquids, if the temperature of the hotter liquid falls below the melting point, the hotter liquid will become a frozen solid

For the the colder liquid, if the temperature is raised above the boiling point, the liquid changes into gas and the temperature does not rise above the boiling point temperature, until all the cold liquid has evaporated

5) For solids, the vibration of the particles of the hotter substance reduces and the solid becomes more brittle

For the colder body, the rise in temperature causes an increase in vibration of the particles, and if the temperature rises above the melting point, the colder solid will begin to melt

One of the pieces of evidence supporting energy quantization was the line spectra of elements. Why does this demonstrate energy quantization?
a) Photons are packets of energy that act both as a particle and a wave.
b) The spectra is continuous and shows emission at all wavelengths.
c) There are sharp emission lines demonstrating discrete energy levels.
d) All compounds emit light in the ultraviolet and visible regions specifically.​

Answers

Answer:

c) There are sharp emission lines demonstrating discrete energy levels.

Explanation:

When an element emits energy in the form of radiation, it produces a spectrum of colors on a photographic plate. This spectrum can either be continuous or discrete. In continuous spectrum the spectrum continues without any discrimination between two regions. This represents the continuous emission of radiation, and thus the continuous emission of energy without any break.

On the other hand, the line spectrum consists of discrete and sharp lines, which shows the emission of radiation in a certain amount in a certain time, with a break between emission. Hence, the line spectra supports the quantization of energy.

The correct option is:

c) There are sharp emission lines demonstrating discrete energy levels.

A student dissolved a 0.139g sample of oxalic acid, H2C2O4, in water in an Erlenmeyer flask. Then the student titrated the H2C2O4 solution in the flask with a solution of KMnO4, which has a dark purple color. The balanced chemical equation for the reaction that occurred during the titration is shown above. (a) Identify the species that was reduced in the titration reaction. Justify your answer in terms of oxidation numbers.

Answers

Answer:

MnO4 − was reduced

C2 O4^2- was oxidized

Explanation:

2MnO4 −(aq)  +5H +(aq)  +2 C2 O4^2-(aq)  +6H+(aq)  →2Mn2+(aq) + 10CO2(g)  +8H2 O(l)

A redox reaction is characterized by a change in the oxidation number of reacting species from left to right in the reaction equation.

If we look at Manganese, its oxidation number was decreased from +7 on the left hand side to +2 on the right hand side. This implies that it gained five electrons. recall that reduction refers to electron gain.

If we look at carbon, its oxidation number increased from +3 on the left hand side to +4 on the right hand side. This indicates loss of one electron and oxidation refers to electron loss.

MnO₄⁻ was reduced and C₂O₄²⁻ was oxidized in the titration.

The balanced chemical equation for the reaction can be expressed as:

[tex]\mathbf{6H^+_{(aq0} + 2MnO_4^-_{(aq)} + 5H_2C_2O_4 _{(aq)} \to 10CO_{2(g)} +8H_2O_{(l)} + 2Mn^{2+}_{(aq)}}[/tex]

A redox reaction can be described by a variation in the oxidation number of reacting species in the chemical reaction equation from the reactant side to the product side

Oxidation takes place when a substance(atom, molecule, or compound) loses an electronReduction occurs when a substance gains an electron.

Let consider Mn in MnO₄⁻, its oxidation number was decreased from +7 on the reactant side to +2 on the product side. This shows a gain of additional five electrons.

Thus, MnO₄⁻ is reduced.

Also in C₂O₄²⁻, the oxidation number of carbon increases from +3 on the reactant side to +4 on the product side. Since an electron is lost, then oxidation  occurs at C₂O₄²⁻

Use the information given to calculate the average atomic mass of element Z. Z- 56 is 70% abundant and Z-59 is 30% abundant.​

Answers

Answer:

56.9 amu

Explanation:

Depending on the number of isotopes an element has, the Average atomic mass of isotopes of an element can be calculated using:

(atomic mass of isotope1 × decimal abundance of isotope1) + (atomic mass of isotope2 × decimal abundance of isotope2)

According to this question, two isotopes of element Z were given

- Isotope Z- 56 with atomic mass 56 is 70% abundance. This means that its decimal abundance is 0.70

- Isotope Z- 59 with atomic mass 59 is 30% abundance. This means that its decimal abundance is 0.30

Therefore, average atomic mass of element Z is:

= (56 × 0.70) + (59 × 0.30)

= (39.2) + (17.7)

= 56.9
