Actuating mechanism is the dry-chemical fixed application method which

introduces a concentration of agent into a closed area.

The actuating mechanism is commonly used in piping systems and

involves the transport of a control member in automatic or remote control

systems.

The closed system makes manual navigation very difficult which is why the

actuating mechanism in automatic systems are usually used to make it less

tedious and accurate.

Answer:

Explanation:

1) Organic compounds always contain only p-block elements (Groups III-VII), at least one of which must be carbon. 2) Organic compounds almost always contain one or more C-H bonds. ... Thus, all bonds are typically covalent in organic compounds. Methane (CH4) is the prototypical organic molecule.

Methane contains carbon, forming covalent bonds, and is found in living organisms, making it an organic compound.

Methane (CH₄) is considered an organic compound due to its molecular structure and occurrence in living organisms. Organic compounds are primarily composed of carbon atoms covalently bonded to hydrogen and often other elements like oxygen, nitrogen, sulfur, and more.

Methane consists of one carbon atom bonded to four hydrogen atoms through covalent bonds. Carbon's unique ability to form stable covalent bonds with other elements, including itself, leads to the vast diversity of organic molecules found in living organisms.

Methane is a crucial component of natural gas and is produced by various biological and geological processes. It is present in the digestive systems of animals, formed during decomposition, and plays a role in carbon and energy cycles.

Its prevalence in living systems and its molecular structure classify methane as an organic compound, reflecting the foundational principles of organic chemistry.

Answer:

8 moles of Fe2O3

Explanation:

You can use the mole ratio give. For every 3 O2 you produce 2 Fe2O3. With this you can find the number of moles. 12 O2 multiplied by the ratio 2/3 gives you 8 moles

    This is not exactly a answer you can use but this is some information that you can use to find out the answer.

    You can usually confirm the charge associate degree particle unremarkably has by the element's position on the periodic table: The alkali metals (the IA elements) lose one negatron to create a ion with a 1+ charge. The alkaline-earth metal metals (IIA elements) lose 2 electrons to create a 2+ ion.

    Nonmetals type negative ions (anions). A range 7|chemical element|element|gas} atom should gain 3 electrons to possess an equivalent number of electrons as AN atom of the subsequent gas, neon. Thus, a gas atom can type AN ion with 3 additional electrons than protons and a charge of 3−.

Answer:

This happens because a metal is less reactive than carbon and it can be extracted from its oxides by heating with carbon. The carbon displaces metal from the compound and removes the oxygen from the oxide.

In the presence of UV light, ethane will react with bromine in a substitution reaction. UV light is the condition under which the reaction will occur so it is written above the arrow in the chemical equation. As the reaction proceeds, the intensity of the re-brown colour of the bromine water decreases.

Answer:

Explanation:

combining bromine and ethane leads to a brown gas or liquid which is made of the elements. it is a gas at room temperature and does not affect human beings. there are many uses for bromine compounds but they are mainly used for the manufacturing of chlorine, fire retadants, water purification, graphy chemicals and pharmaceutcals. it is a naturally occurring element that can be found in animals such as sharks since they produce their own.

NaCl has a cubic unit cell, best thought of as a face-central cubic array of anions with an interpenetrating FCC action lattice or (vice versa). The cell looks the same whether you start with anions or cations on the corners. Each ion is 6 co-ordinates and has a local octahedral geometry.

NaCl lattice exhibit  cubic unit cell.  The face-centered cubic array of anions with an interpenetrating fcc cation lattice are seen in 3D structure. Each ion is 6-coordinate and has a local octahedral geometry.

Sodium chloride is an ionic compound, formed from the sodium metal and chlorine atom. The ionic bond is formed by loss of one electron from sodium metal to the chlorine atom.

The lattice structure of all metals contains a pool of cations in the sea of mobile electrons.  The electrons can be delocalized into the interstices and thus metals conduct electrically and thermally.

In the fcc lattice of NaCl,  sodium atoms are arranged at the corners and Cl atoms are at the center of each cube face of the cell. They are assumed to touch along face diagonals.

Atoms are arranged at the corners of the cube with another atom at the cube center also hence there will 4 atoms one unit cell.

Answer: Ne ( Neon )

Explanation: Lithium ( Li ), beryllium ( Be ), carbon ( C ), oxygen ( O ), and neon ( Ne ), are all in Period 2 in that order. Sodium ( Na ) is in Period 3. Since electron affinities decrease as you go down, Na would have a lower electron affinity level then Li but since electron affinities increase as you go across a period, only neon is farther right then oxygen ( O ), so it would be the only one element of this group that would have a higher electron affinity than that of oxygen.

There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Option C is correct option.

Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.

Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can discover the new elements that are not being discovered yet.

On going down the group electronegativity decreases. On going along the period the electronegativity increases. So, Neon lies on the extreme right of Fluorine in the same period. Neon will have more electronegativity than oxygen.

Therefore, Neon is more electronegativity than fluorine.

Answer:

electrical forces between particles, as given by coulombs law.

Explanation:

Properties of a substance such as vapor pressure and surface tension depend on electrical forces between particles, as given by Coulomb's law.

The vapor pressure refers to how easily a liquid converts to gas while surface tension is the force that makes a liquid surface act as a stretched elastic skin.

Both vapor pressure and surface tension has a lot to do with the degree of polarity in a molecule. Usually, polar molecules have a low vapor pressure and high surface tension due to a high electrical forces between particles, as given by Coulomb's law.

This problem is giving information about the proton concentrations of three solutions at 25 °C. Despite they are not numerically given, we can propose three scenarios to see how to approach the question.

Let the following solutions to come up:

[H⁺] = 2.63x10⁻³ M

[H⁺] = 1.00x10⁻⁷ M

[H⁺] = 4.511x10⁻⁹ M

The first step, will be the calculation of the pH for each solution via:

pH = -log([H⁺])

So that they turn out to be:

pH = -log(2.63x10⁻³ M) = 2.580

pH = -log(1.00x10⁻⁷ M) = 7.000

pH = -log(4.511x10⁻⁹ M) = 8.3457

In such a way, since acidic solutions have a pH below 7, neutral have a pH equal to 7 and basic have it above 7, we infer the first one is acidic, second one is neutral and third one is basic.

Thus, you can reproduce this methodology with the proton concentrations you are given.
