Answer:

Na3Po3 is soluble in water

Sodium phosphite, often referred to as [tex]Na_3PO_3[/tex], is generally considered to be water soluble.

Because the sodium cation (Na+) has a significant affinity for water molecules due to their positive charge, sodium compounds generally have a tendency to be soluble in water. The three sodium ions increase the solubility of [tex]Na_3PO_3[/tex] and make it even more soluble.

The solubility of [tex]Na_3PO_3[/tex]  is similarly affected by the phosphate ion [tex](PO^3^-)[/tex]. Phosphates are normally soluble in water unless they are coupled with cations that generate intractable compounds, like some heavy metal ions. The strong ion-dipole interactions between sodium ions and water molecules can be used to explain why [tex]Na_3PO_3[/tex] is soluble in water.

Answer:

Liquied A

Explanation:

It is at the top and it is the lightest if it is at the bottom then it has the most density

Answer:

Fatty acids

Explanation:

Acetyl coA is a compound vital for the process of cellular respiration in the mitochondria. It is the starting material of the kreb's cycle or TCA cycle, which takes place in the mitochondria. During the metabolism of glucose (glycolysis), a molecule called PYRUVATE is first synthesized before becoming acetyl coA in the mitochondrion.

However, the metabolism of FATTY ACIDS (monomers of lipids) directly gives rise to acetyl coA without first becoming pyruvate. The fatty acids molecule undergo Beta- oxidation to produce acetyl coA, which enters the TCA cycle to continue cellular respiration.

Electron configurations correspond to an excited state is 1s₂, 2s₂, 3p₁.The electrical configuration 1s₂, 2s₂, 3s₁ demonstrates that the atom is in the excited state.

The distribution of an atom's or molecule's electrons in atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry.

An electron is in an excited state when it momentarily possesses an energy level higher than its ground state. If an electron receives more energy, such as when it absorbs a photon, or packet, of light, or collides with an adjacent atom or particle, it can become excited.

The primary distinction between a system's ground state and excited state is that a system's ground state is any condition in which its electrons are at their lowest potential energy levels, whereas an excited state is any state in which they are at an energy greater than the system's ground state.

Thus option A is correct.

Explanation:

Answer:

It is way too long I can't help with it Honestly

An element in the same row with roughly half of the atomic mass always has a greater atomic radius.

Atomic radius:  It is the distance between the nucleus and the outermost shell.

Atomic mass: It is the mass or the number of nucleons or protons and neutrons inside an atom.

In a row, the number of protons increase but the number of shells remains constant.

Hence, the positive protons in the nucleus attract electrons with more electrostatic force.

Therefore,  an element in the same row with roughly half of the atomic mass always has a greater atomic radius.

Answer:

theres gonna be more energy and some of the particles with a lot of energy will become vapor and evaporate

Explanation:

"If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapor as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away."

___________________________________________________________

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

A condensation reaction is a class of organic addition reaction that typically proceeds in a step-wise fashion to produce the addition product, usually in equilibrium, and a water molecule.Hydrolysis is any chemical reaction in which a molecule of water ruptures one or more chemical bonds.

Different:

A condensation reaction that occurs between two separate molecules is called intermolecular condensation. ... The opposite of a condensation reaction that releases a water molecule is called a hydrolysis reaction. This happens when one molecule is split into two via the addition of a water molecule.

Answer: The molar enthalpy of formation for paraffin wax  is  -2460.5 kJ

Explanation:

The balanced chemical reaction is,

[tex]C_{25}H_{52}(g)+38O_2(g)\rightarrow 25CO_2(g)+26H_2O(g)[/tex]

The expression for enthalpy change is,

[tex]\Delta H=\sum [n\times \Delta H_f(product)]-\sum [n\times \Delta H_f(reactant)][/tex]

[tex]\Delta H=[(n_{CO_2}\times \Delta H_{CO_2})+(n_{H_2O}\times \Delta H_{H_2O})]-[(n_{O_2}\times \Delta H_{O_2})+(n_{C_{25}H_{52}}\times \Delta H_{C_{25}H_{52}})][/tex]

where,

n = number of moles

[tex]\Delta H_{O_2}=0[/tex] (as heat of formation of substances in their standard state is zero

Now put all the given values in this expression, we get

[tex]-14800=[(25\times -393.5)+(26\times -285.5)]-[(38\times 0)+(1\times \Delta H_{C_{25}H_{52}})][/tex]

[tex]\Delta H_{C_{25}H_{52}}=-2460.5kJ/mol[/tex]

Therefore, the molar enthalpy of formation for paraffin wax  is -2460.5 kJ
