When a substance changes from liquid to gas, what happens to the motion of its particles?

Moles of Bromine produced = 9 moles

Given

9 moles of Chlorine gas

Word equation

Required

Moles of Chlorine produced

Solution

We change the word equation into a chemical equation (with a formula)

Aluminum bromide reacts with chlorine gas to produce Aluminum chloride and bromide gas

2AlBr₃+3Cl₂⇒2AlCl₃+3Br₂

moles Cl₂ = 9

Maybe you mean, how many moles of Bromine can we produce?

From equation, mol ratio Cl₂ : Br₂ = 3 : 3, so mol Br₂=mol Cl₂=9 moles

It would take approximately 0.144 hours to produce 7.5 moles of copper metal using the given current and cell potential.  

To produce 7.5 moles of copper metal from an electrolytic cell, we can use the following equation:

moles of copper produced = moles of Cu produced

here:

moles of Cu produced is the number of moles of Cu that are produced as the Cu ions dissolve in the solution and move towards the cathode.

We are given that the current passed through the cell is 50.0 A and the cell potential is 2.50 V. Therefore, we can calculate the number of moles of Cu produced using the following equation:

moles of Cu produced = -50.0 A x 2.50  x time

To find the time required to produce 7.5 moles of copper, we can rearrange the equation as follows:

time = -moles of Cu produced / (50.0 A x 2.50 V)

time = -7.5 moles / (50.0 A x 2.50 V)

time = 0.144 hours

Therefore, it would take approximately 0.144 hours to produce 7.5 moles of copper metal using the given current and cell potential.

Answer:

volume = 16.8

Explanation:

From the question

The Mass = 1.5g.

Molar mass = H2

= 1×2 =2

mole = ?

\(mole = \frac{mass}{molar \: mass} \\ mole = \frac{1.5}{2} \\ mole = 0.75mol\)

Therefore the volume =

\(v = v {dm}^{3} \times n\)

Where mole(n)=0.75mol.

vdm³=22.4dm³

\(v = 22.4 \times 0.75 \\ v = 16.8\)

Therefore the volume = 16.8.

One of the roles of the kidneys is to help buffer body fluids and maintain their pH within a narrow range. The cells of the renal tubule secrete hydrogen ions (H+) into the tubule lumen and absorb bicarbonate ions (HCO3-) from the tubular fluid.

The kidneys play a vital role in maintaining the acid-base balance of the body. One way they achieve this is through the regulation of hydrogen ions (H+) and bicarbonate ions (HCO3-).

In the renal tubule, specialized cells actively secrete hydrogen ions into the tubule lumen. This process is known as tubular secretion. By secreting hydrogen ions, the kidneys can help eliminate excess acids from the body and regulate the pH of the urine.

Simultaneously, the renal tubule cells reabsorb bicarbonate ions from the tubular fluid. Bicarbonate ions are important buffers that can neutralize excess acids in the body. By reabsorbing bicarbonate, the kidneys can maintain the balance of these ions and prevent excessive acidification of body fluids.

This coordinated secretion of hydrogen ions and absorption of bicarbonate ions by the cells of the renal tubule contribute to the kidneys' role in buffering body fluids and preventing excessive acidity or alkalinity.

Explanation:

Answer:

Explanation:

Similarly, if we heat a volume of water above 100 degrees Celsius, or 212 degrees Fahrenheit, water changes its phase into a gas called water vapor. Changes in the phase of matter are physical changes, not chemical changes.

The decolorizer in the acid-fast stain is acid-alcohol, and the counterstain is methylene blue.

In the acid-fast stain, acid-alcohol is used as the decolorizer. It plays a crucial role in removing the primary stain (carbolfuchsin) from non-acid-fast cells while leaving the acid-fast cells stained. This helps differentiate acid-fast bacteria from non-acid-fast bacteria or other cellular components.

After decolorization, methylene blue is used as the counterstain in the acid-fast stain. It provides contrast to the acid-fast cells that retained the primary stain and were not decolorized, allowing them to be easily visualized and distinguished.

In the acid-fast stain, the decolorizer used is acid-alcohol, which selectively removes the primary stain from non-acid-fast cells. The counterstain employed is methylene blue, which helps visualize the acid-fast cells that retained the primary stain. This staining technique is commonly used to detect acid-fast bacteria, such as Mycobacterium tuberculosis, in clinical and microbiological settings.

Answer: I don’t know ask my teacher

Explanation:

The sample made of the substance with a higher specific heat capacity would be object B.

If two objects of the same mass and same initial temperature are given the same amount of heat, but one of them (Object A) experiences a greater temperature increase than the other (Object B), then Object A must have a lower specific heat capacity than Object B.

The specific heat capacity is a measure of how much heat energy is required to raise the temperature of a substance by 1 degree Celsius. A substance with a higher specific heat capacity requires more heat energy to raise its temperature by the same amount compared to a substance with a lower specific heat capacity.

In this case, since both objects received the same amount of heat energy but Object A experienced a greater temperature increase than Object B, we can conclude that Object A must have a lower specific heat capacity than Object B.

Therefore, the sample that is made of the substance with the higher specific heat capacity must be Object B.

The particular significance of valence electrons is - 2) Valence electrons form chemical bonds between atoms by being transferred or shared.

A valence electron is an electron that is part of an atom's outer shell and can take part in the synthesis of a chemical bond if the outer shell is open. Each atom in the bond contributes one valence electron, forming a shared pair in a single covalent bond. Atoms are bound together by attractive forces called chemical bonds. Valence electrons, which make up an atom's outermost electronic "shell," interact to form bonds. Covalent bonds are the bonds in which the valence electron density is shared by the two atoms. They are formed between atoms with equal or similar electronegativity.

Valence electrons are exchanged between atoms, usually a metal and a nonmetal, to create ionic bonds. Ions can follow the octet rule and become more stable when one or more of their valence electrons are lost or gained. Ions therefore interact in ways that balance their charges. Chemists examine the exchange or sharing of electrons during chemical reactions. The valence electrons that are lost, gained, or shared are those electrons.

Explanation:Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food

Explanation:

By Avagadro's Law,

V¹n¹ = V²n², where P and T are constant.

Therefore (4.00L)(0.200mol) = (3.25L)n²,

n² = 0.246mol. (3s.f.)

P.S. n² does not mean the square of n in this case, it is just a subscript.

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Combined Boyle's and Charles' gas law is used here. Therefore, 0.246mol of gas remain if some of the gas is released and the new volume is 3.25 L.

Ideal gas equation is the mathematical expression that relates pressure volume and temperature.

Mathematically the relation between Pressure, volume and temperature can be given as

PV=nRT

where,

P = pressure of ideal gas

V= volume of ideal gas

n =number of moles of ideal gas

T =temperature of ideal gas

R = Gas constant = 0.0821 L.atm/K.mol

By Avagadro's Law,

V₁n₁= V₂n₂, where P and T are constant.

V₁×n₁= V₂×n₂,

(4.00L)(0.200mol) = (3.25L)n²

n₂ = 0.246mol.

Therefore, 0.246mol of gas remain if some of the gas is released and the new volume is 3.25 L.
