Answer:

Its Neon

Explanation:

Why ? Because Neon is the fastest it can go to 435 m/s and thats one of the fastest element there.

Helium would have the fastest rate of diffusion. Therefore, option (C) is correct.

Graham’s law states that the rate of diffusion of a gas is inversely proportional to the square root of the molecular weight of that gas.

According to Graham’s Law, molecules of gas with lower molecular mass at constant pressure and temperature will diffuse faster than the higher molecular mass molecules. This formula is commonly utilized to compare the rates of diffusion of two different gases at the same pressures and temperatures.

[tex]\frac{Rate_1}{Rate_2} =\sqrt{\frac{M_2}{M_1} }[/tex]

Where M₁ is the molar mass of gas 1 while M₂ is the molar mass of gas 2.

The atomic mass of He, Ne, Ar, and Ke is 4, 20, 40, and 83 g/mol. The helium gas has the lowest atomic mass so it has the highest rate of diffusion while Krypton has the lowest rate of diffusion.

Answer: The fourth material that is added to the blast furnace is HOT AIR which provides OXYGEN for used for combustion of carbon (Coke).

Explanation:

Iron is the second most abundant metal found in the earth's crust after aluminium. It is not found in the free metallic state but are extracted from rocks which are rich in iron that contains other materials. These are known are iron ores and the most common iron ores are haematite ( Fe2O3).

Iron can be extracted from its ore with the used of blast furnace. The materials used for extraction of iron includes:

--> Coke

--> haematite( iron ore)

--> limestone and

--> Hot air.

The iron ore is first roasted in air so that iron(III)oxide is produced. The iron(III)oxide is then mixed with coke and limestone and heated to a very high temperature. Hot air is introduced into it from the bottom of the furnace. The coke is oxidizes the the oxygen in the hot air blast to liberate carbondioxide.

Answer:

C

Explanation:

Answer:

At 4°C what is not able to decompose into hydrogen and oxygen chemical changes cannot be reverted, in this case it can. It will not change color, because water is always clear, and won't at this state turn into ice. though it can be reverted.

Answer:

1. answer is subcutaneous tissue 2. answer is spleen

Explanation:

The subcutis is also known as the hypodermis or subcutaneous layer, and functions as both an insulator, conserving the body's heat, and as a shock-absorber, protecting the inner organs.

Excretory Organs. Organs of excretion include the skin, liver, large intestine, lungs, and kidneys. Together, these organs make up the excretory system.

Answer:

the answer is Subcutaneous Tissue

Explanation:

Answer:

The sequence from longest wavelength (radio waves) to shortest wavelength (gamma rays) is also a sequence in energy from lowest energy to highest energy. Remember that waves transport energy from place to place. The energy carried by a radio wave is low, while the energy carried by a gamma ray is high.

Answer:

Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis.

Answer:

True.

Explanation:

Answer: Formula: q = mcΔT,

- q is the amount of heat transferred

- m is the mass of the substance

-  c is the specific heat capacity of the substance

- ΔT is the change in temperature

q= 733 J

m=  312g

ΔT = 15 °C

Calculate this together  = 733 J / 312g  x 15 °C

= and then you can find your  answer for c.

Explanation:

Answer:

The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.

Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

Explanation:

I looked it up and this was the answer for your question

Answer:

23 g sodium

Explanation:

In chemistry, one mol (1mol) of a substance equals Avagadro's number or constant (6.02 × 10^23 atoms/particles/molecules).

According to this question in which the mass of different elements were given, the mass of the element that equals 6.02 × 10^23

Using the formula; mole = mass/molar mass

- Sodium = 23g/23g/mol = 1mol

- Krypton = 42g/84g/mol = 0.5mol

- Carbon = 24g/12g/mol = 2mol

- Pottasium = 78g/39g/mol = 2mol

Therefore, from the above illustration, it can be observed that only 23g of sodium contains 1 mol, hence, 23g sodium contains 6.02 × 10^23 atoms.

Answer:

make sure that the number of atoms on the left side of the equation equals the number of atoms on the right.

Explanation:

A chemical reaction can be balanced by multiplying each side with suitable integers such  that the number of each element in the reaction must be equal number on both side.

According to the law of conservation of mass for  a chemical reaction, the total mass in the reactant side is equal to the total mass in the product side. Thus, a balanced chemical equation represents the perfect stoichiometry for each reactants and products.

The number of each elements in both side have to be equal in number. If they are unequal on both side, we can balance the reaction by multiplying with suitable integers.

Lets have one example. Consider the given reaction.

[tex]\rm CH_{4} + O_{2} \rightarrow H_{2}O + CO_{2}[/tex]

Here, 4 H are in left side and only 2 in right side. Similarly number of oxygen also not balanced.

The balanced equation requires a coefficient of 2 for water and 2 for oxygen in reactant thus, it can be written as:

[tex]\rm CH_{4} + 2O_{2} \rightarrow 2H_{2}O + CO_{2}[/tex]
