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

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]

Answer: 1

Explanation: This is true.

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.

Answer:

The laws of the universe are for all observers, and it was shown that the velocity of light in spacetime will be the same regardless of the subject's speed.

Explanation:

The principle outlines how things behave in time and space, so it could be used to model anything from black hole life to light shifting due to the gravitational, as well as the action of the terrestrial Planets in its orbit. Einstein's most popular hypothesis has far-reaching ramifications.

Answer: Solids

Explanation:

Solids have a definite volume and structure. These are comprised of atoms, ions, and molecules closely packed together giving a confined structure to the solids. The particles are bound with strong force of attraction. The particles in the solid are arranged in an repeated, orderly, and three dimensional pattern. Depending upon the substance of the solid the particles within the solid can be ions, atoms, and can be molecules.

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.

The correct answer is B) El Nino/La Nina

Explanation:

El Nino and La Nina are climate patterns that can cause modification to the global weather conditions. They are present in the Pacific Ocean.

El Nino is Spanish for Little Boy. It is characterised by warm weather, while La Nina in Spanish refers to Little Girl. La Nina is characterized by cool/cold currents.

Answer:

temperature

Explanation:

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.

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:

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

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.

Answer:

The Coriolis effect is an apparent deflection in the paths of moving objects caused by Earth's faster speed near the equator than near the poles. In the solar system, the greatest expression of this effect occurs in planetary atmospheres. On Earth, for example, the air around us moves freely above the ground.

Explanation:

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!!

Answer:

Thermal Energy

Explanation:

The thermal energy of an object increases as the temperature increases, causing atoms and molecules to move faster. When the temperature decreases, the thermal energy decreases, causing atoms and molecules to move slower. Another term for thermal energy is heat energy.

Answer:

Temperature and precipitation

Explanation:

They determine how quickly weathering will be, and what kind of organic material may be available on the inside of the soils.

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.

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.
