Place the characteristics for each phase of matter into the table where it belongs

Answers

Answer:

Solid- Definite shape

Solid and Liquid- Definite volume, Not easy to compress, if at all

Gas- No Definite Volume

Liquid and Gas- No Definite shape

The characteristics for each phase of matter in the table where it belongs are as follows:

Solids: Definite shape, very little particle motion. Liquids: Fluid motion. Gases: No Definite Volume, easily compressed. Solids and liquids: Definite volume, Not easy to compress, if at all. Liquids and Gases: No Definite shape, constant, fast particle motion.

What are the different States of matter?

The states of matter may be defined as the three distinct physical forms which matter can take in most environments. They are as follows:

Solid.Liquid.Gas.

Each of the states of matter significantly possesses specific chemical and physical properties. For example, solids generally have a definite volume, are relatively rigid, and atoms or molecules are attached to each other very compactly.

Liquids possess a definite volume and have the ability to alter their shape through flowing. The atoms are loosely bonded to one another.

Gas has no definite volume or shape. This state of matter is easily compressed as well.

Therefore, the characteristics for each phase of matter in the table where it belongs are well described.

Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.

What is soil?

The bioactive, porous media that has grown in the top layer of the Earth's crust is known as soil. Being a source of water as well as nutrients, a filter for harmful wastes, a site for their breakdown, and a participant inside the cycle of elements such as carbon through the planet's ecosystem, soil constitutes one of the main substrates of life on Earth.

It has changed as a result of weathering processes influenced by geographical, geologic, biological, and climatic factors. A practical understanding of soils including their management has also developed out of need since the development of agriculture with forestry in the eighth millennium BCE. Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.

Therefore, temperature and precipitation is the major determining factor in soil formation.

How many moles are in 5.8 x 1024 atoms of C?

Answers

Answer:

No of moles of carbon = 9.63 mol

Explanation:

No of atoms of carbon = 5.8 × 10²⁴

Avogadro's no. = 6.022 × 10²³

No. of moles = No. of atoms / Avogadro's no.

N = 5.8 × 10²⁴ / 6.022 × 10²³

N = 9.63 mol

∴ No of moles of carbon = 9.63 mol

The acidic ingredient in vinegar is acetic acid. The pH of vinegar is around 2.4, and the molar concentration of acetic acid in vinegar is around 0.85 M. Based on this information, determine the value of the acid ionization constant, Ka, for acetic acid.

Answers

Answer: The value of acid ionization constant [tex]K_a[/tex] for acetic acid is [tex]1.87\times 10^{-5}[/tex]

Explanation:

[tex]CH_3COOH\rightarrow H^+CH_3COO^-[/tex]

 cM              0             0

[tex]c-c\alpha[/tex]        [tex]c\alpha[/tex]          [tex]c\alpha[/tex]  

So dissociation constant will be:

[tex]K_a=\frac{(c\alpha)^{2}}{c-c\alpha}[/tex]

Give c= 0.85 M and [tex]pH[/tex] = 2.4

[tex]pH=-log[H^+][/tex]

[tex][H^=}=c\times \alpha=10^{-2.4}=3.98\times 10^{-3}[/tex]

[tex]K_a=?[/tex]

Putting in the values we get:

[tex]K_a=\frac{(3.98\times 10^{-3})^2}{(0.85-3.98\times 10^{-3})}=1.87\times 10^{-5}[/tex]

Thus the value of acid ionization constant [tex]K_a[/tex] for acetic acid is [tex]1.87\times 10^{-5}[/tex]

what was the mass of the soil? Show your work.

Answers

Answer:

m = 7.42 kg

Explanation:

Given that,

The specific heat of the soil, c = 1.700J/g C

The temperature of soil in a  flowerpot increased from 15.6°C to 35.5°C.

The energy released from the Sun is 251175 J. We need to find the mass of the soil.

We know that,

[tex]Q=mc\Delta T\\\\or\\\\m=\dfrac{Q}{c\Delta T}\\\\m=\dfrac{251175}{1.7\times (35.5-15.6)}\\\\m=7424.62\ g[/tex]

or

m = 7.42 kg

So, the mass of the soil is equal to 7.42 kg.

If people had not extracted fossil fuels from Earth to use as energy, would this carbon be "cycling" within the global carbon cycle we have defined today?

Answers

Answer: The answer is YES. There would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use.

Explanation:

Carbon is an element in the periodic table with the atomic number of 12. It has 4 electrons on its outermost shell in the electronic configuration. These are valence electrons which are used to form bonds in a wide range of both organic and inorganic compounds, giving rise to simply molecules like carbondioxide.

CARBON CYCLE is a natural process through which carbon and it's compounds are kept fairly constant through recycling. They are found in fossils fuels such as oil, coal, and natural gas. When these fossil fuels are burnt and used as energy, carbon is released in form of carbondioxide. This is just one of the ways carbon is returned to the atmosphere. Other ways include:

--> respiration of plants and animals

--> decomposition of organic substances

--> action of dilute acids and heat on trioxocarbonates (V) and hydrogen trioxocarbonates (IV).

Carbon is then removed from the atmosphere through:

--> plants in photosynthesis

--> rain water as weak trioxocarbonate (IV) acid.

Therefore, there would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use because the burning of fossil fuels is not the only way carbon is returned to the atmosphere during carbon cycle.

Answers

Answer:

Reaction

Mg+H2SO4 ----》MgSO4+H2

so calculate the moles of magnesium first

moles of magnesium = given mass of mg/molar mass of magnesium

moles = 4/24.30

moles = 0.1646

One mole of magnesium produces one mole of magnesium sulphate

so 0.1646 moles of mg will produce 0.1646 moles of MgSO4

Mass of MgSO4 = 0.1646× 120.366

MgSO4 = 19.81 gm

conclusion the mass of magnesium sulphate that would be obtained from 4g of

magnesium is 19.81 gm!!

What is the pH of a 1.0 x 10-4 M solution of KOH?

Answers

Answer:

pH = 10

Explanation:

KOH is a strong base; thus it will completely dissociate:

KOH -> K⁺ + OH⁻

Since it completely dissociates, the concentration of both K⁺ and OH⁻ will be the concentration of KOH given (1.0 x 10^-4 M).

We can then find pOH by taking the negative log of the OH⁻, or hydroxide, concentration:

pOH = -log[OH⁻] = -log[1.0 x 10^-4 M] = 4

At 25 degrees Celsius, pH + pOH = 14. If we solve for pH and then plug in our pOH, we get:

pH = 14 - pOH = 14 - 4 = 10

The pH of a 1.0 x 10^-4 M solution of KOH is thus 10.
