Answer 1

The Products are the chemicals that emerge from the process.

What is chemical reaction?

A method where one or more substances, known as reactants, are transformed into one or more new substances, known as products. Substances are made of chemical building blocks or chemical compounds.

What is solid ?

As one of the four fundamental states of matter, a substance is said to be in the solid state when it is in that condition. Atoms in solids are closely packed together and have significantly lower kinetic energy than those in liquids and gases.

Chemical reactions are initiated by reactants, which are the substances that do so. Products are the chemicals that emerge from the process.

A hydrogen bond would form between the hydrogen atom in the ammonia molecule and the oxygen atom in the water molecule.

What is bond?
An enduring attraction between ions or atoms known as a chemical bond is what allows molecules and crystals to form. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds. Covalent, ionic, and metallic bonds are examples of "strong bonds" or "primary bonds," whereas dipole-dipole interactions, this same London dispersion force, and hydrogen bonding are examples of "weak bonds" or "secondary bonds."

Answers

32.18 KJ/mol of heat will be released if 0.4501 mol of NH₃ are mixed with 0.200 mol of O₂.

Limiting reagent- The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. The precise quantity of reactant required to react with another element can be estimated from the reaction stoichiometry.

1 mole of O₂ and 4 moles of NH₃ reacts-

therefore,

A reaction between 0.4501 mole of NH₃ should occur with 0.4501 x 1 / 4 = 0.1013 moles of O₂

O₂ is an excess reagent, and NH₃ is a limiting reagent.

286 KJ/mol of energy are released by 4 moles of NH₃.

There is more CO2 evaporating into the ocean as a result of human-driven increases in atmospheric carbon dioxide levels. The average pH of the ocean is currently 8.1, which is basic (or alkaline), but when more CO2 is absorbed, the pH drops and the ocean turns more acidic.

What is pH?

pH is a measurement of how acidic or basic an aqueous solution is in relation to other liquids.

Answer:

Explanation:

I will assume that r.t.p. is supposed to be STP, Standard Temperature and Pressure.  rtp might refer to room temperature and pressue, but no value is given for room temperature, so let's assume standard temperature (0 degrees Celsius).  Here is a marvelous, and useful, property of gasses at STP:  One mole of gas at STP occupies 22.4 liters.  Let's make that a conversion factor:  (1 mole/22.4 liters).

We have the volume of gas at STP:  360 cm^3.  Convert that into liters:

(360cm^3)*(1 ml/cm^3)*(1 liter/1000 ml) = 0.360 liters(L)

Now use the conversion factor from above to convert the volume of gas into moles of gas:

 (0.360L)*(1 mole/22.4 liters) = 0.0161 moles of gas

By definition, 1 mole is 6.02x10^23 particles, or molecules of the gas.

Convert moles of the gas to molecules:

(0.0161 moles)*((6.02x10^23 molecules)/mole) = 9.68x10^21 molecules of nitrogen.

the diagrams above represent two allotropes of solid phosphorus. which of the following correctly identifies the allotrope with the higher melting point and explains why?

Answers

Allotrope 1 has the higher melting point because it lacks the covalent bonds between phosphorus atoms that are present in allotrope 2.

The Melting Point Differences Between Allotropes of Solid Phosphorus

Allotropes of solid phosphorus are different forms of the element which differ in their molecular arrangement and structure. Allotrope 1 is a more stable form and has a higher melting point than that of allotrope 2 due to the absence of covalent bonds between the phosphorus atoms in allotrope 1.

The structure of allotrope 1 is an ordered arrangement in which the phosphorus atoms form a three-dimensional lattice. This lattice structure is held together by strong Van der Waals forces, which are electrostatic attractions between the atoms. This structure is more stable than that of allotrope 2 and has a higher melting point due to the increased strength of the interatomic forces.

In contrast, the structure of allotrope 2 is much less ordered, and the phosphorus atoms are held together by covalent bonds. This structure is not as stable as that of allotrope 1 and has a lower melting point. The covalent bonds between the phosphorus atoms are much weaker than the forces in allotrope 1, and consequently the melting point of allotrope 2 is lower.

Answers

The solubility (in g/l) of caso4(s) in 0.300 m na2so4(aq) at 25°c is 0.016762 g/mol.

Solubility is defined as the maximum amount of a substance in an effort to dissolve in a given quantity of solvent at a special temperature. Solubility is a characteristic asset of a particular solute-solvent combination, and special substances have significantly differing solubilities.

Solubility of CaSO₄; K_sp = 4.93 × 10⁻⁵

Concentration of Na₂SO₄ = 0.4 M

The ionic equation of CaSO₄ is given as;

CaSO₄ ⇒ Ca²⁺ + SO₄²⁻

Now, the formula for solubility ,

K sp = [A⁺]ᵃ × [B⁻]ᵇ

Thus, plugging in relevant values into the solubility equation -

4.93 × 10⁻⁵ = Ca²⁺ × 0.4

Ca²⁺ = ( 4.93 × 10⁻⁵)/0.4

Concentration of Ca²⁺ = 12.325 × 10⁻⁵ M

The molar mass of CaSO₄ =  136 g

Hence, solubility of CaSO₄ in 0.4M of Na₂SO₄ is 12.325 × 10⁻⁵ M × 136 g/mol = 0.016762 g/mol
