How can the strength of an acid be determined using titration? Will give brainilist too

A nuclear reaction can be controlled using which of the following?

gavmur [86]

Control rods is regarded as a substance which can control nuclear reaction and is denoted as option A.

<h3>What is Nuclear reaction?</h3>

This is a type of reaction which involves the nuclei of an atom being split or joined together and is usually accompanied with a great amount of energy emitted in the form of heat.

The two types of nuclear reaction include:

Nuclear fusion

Nuclear fission

Nuclear fusion involves the collision of two or more nuclei in other form a new atom while nuclear fission involves splitting the atoms to form other products and involves a very high amount of energy and exposure to organisms should be prevented as the radiations can alter DNA.

Control rods are commonly used in nuclear reactors and control the rate of fission in the fuel used. This is therefore the reason why it was chosen as the most appropriate choice.

What's the partial pressure of carbon dioxide in a container that holds .35 atm of nitrogen, and .12 atm of hydrogen and has a t

ivanzaharov [21]

Answer:

0.58 atm

Explanation:

Step 1: Given data

Total pressure of the gaseous mixture (P): 1.05 atm

Partial pressure of N₂ (pN₂): 0.35 atm

Partial pressure of H₂ (pH₂): 0.12 atm

Partial pressure of CO₂ (pCO₂): ?

Step 2: Calculate the partial pressure of CO₂

The total pressure of the gaseous mixture is equal to the sum of the partial pressures of the individual gases.

P = pN₂ + pO₂ + pCO₂

pCO₂ = P - pN₂ - pO₂

pCO₂ = 1.05 atm - 0.35 atm - 0.12 atm = 0.58 atm

Arrange the following molecules according to the strength of their dispersion forces.

Kitty [74]

<u>Answer:</u>

D<u>ispersion force :</u> is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make form temporary dipoles. This force is also called an induced dipole-induced dipole attraction because one molecule induce dipole in other molecule. London forces are the attractive forces that cause non polar substances to condense to liquids and to freeze into solids when the temperature is lowered sufficiently.

<u>Molecular size :</u>

•Larger and heavier atoms and molecules exhibit stronger dispersion forces than lighter and smaller ones.

•In a larger atom or molecule, the valence electrons are, farther from the nuclei than in a smaller atom or molecule. They are less tightly bounded and can more easily form temporary dipoles.

<u>Molecular shape: </u>

•At room temperature, neopentane (C5H12) is a gas whereas n-pentane (C5H12) is a liquid.

•London dispersion forces between n-pentane molecules are stronger than those between neopentane molecules even though both molecules are nonpolar and have the same molecular weight.

•The somewhat cylindrical shape of n-pentane molecules allows them to come in contact with each other more effectively than the somewhat spherical neopentane molecules.

so here ,

2 > 3 > 1 > 4 > 5 > 6

1st have more dispersion force because it is n heptane present in liquid form.

6th have lowest force because it is present in gaseous form.

Classify these substances? More than one answer may apply in each case.

dalvyx [7]

Answer:

N2 element, pure substance

O2 element, pure substance

N2O Compound, pure substance

Air (mostly N2 and O2 ) homogeneous mixture

Explanation:

N2, Nitrogen is known as the chemical element that is characterized by having atomic number 7 and that is symbolized by the letter N, in its molecular version, it is recognized as N2.

O2, Oxygen is the chemical element of atomic number 8, this molecular form is composed of two atoms of this element.

A chemical element is a type of matter, consisting of atoms of the same class.

N2O, Nitrous oxide is formed by the union of two molecules of nitrogen and one of oxygen, which is considered a chemical compound since it is a substance formed by the chemical combination of two different elements of the periodic table.

A pure substance is one that cannot change state or divide into other substances, except for a chemical reaction.

Air (mostly N2 and O2 ), it is a homogeneous mixture of gases that constitutes the earth's atmosphere. A homogeneous mixture is a type of mixture in which its components are not distinguished and in which the composition is uniform and each part of the solution has the same properties.
