A reaction between an acid and a base describes a neutralization reaction. Therefore, option (a) is correct.

A neutralization reaction can be described as a chemical reaction in which an acid and base react with each other to produce salt and water.

The acidic strength of the reactant gives the pH of the neutralized solution. When a strong acid solution will react with a strong base the formed salt can be neither acidic nor basic, it will be neutral. For example, when HCl (a strong acid) reacts with NaOH (a strong base), the resulting salt is sodium chloride (NaCl) and water.

HCl    +    NaOH   →   NaCl   +   H₂O

When a strong acid solution will react with a weak base, then the formed salt will be acidic in nature. When a strong base solution will react with a weak acid then the formed salt will be basic in nature and decides the pH level of the solution.

Therefore, the reaction between the acid and base can best describe a neutralization reaction.

Hydrogen has 1 outer shell which contains 1 electron.

the lightest known stable subatomic particle, the electron. The fundamental unit of electric charge, the coulomb, which has a negative charge of 1.602176634 1019 is carried by it. Only 1/1,836 the mass of a proton, 9.1093837015 1031 kg, is the rest mass of an electron. Since an electron has almost negligible mass compared to a proton or neutron, its mass is not taken into account when determining an atom's mass number.

During his studies of cathode rays, the English scientist J.J. Thomson made the discovery of the electron in 1897. His discovery of electrons—which he first referred to as corpuscles—played a crucial part in altering our understanding of atomic structure. In normal circumstances, electrons are bonded to the positively charged atomic nuclei.

B, C, and D are statements that best describe why explanations of results might differ considering hypothesis.

An informed estimate or speculative explanation for a phenomenon or observable occurrence that may be tested by more research is called a hypothesis. It is a hypothesis that may be supported or refuted by experiments or observations and is founded on past information, observations, and reasoning. A key component of the scientific process, a hypothesis is a statement that may be tested by investigation or observation. Predictions regarding the outcome of an experiment or observation are frequently made using hypotheses; if the predictions are verified by the data, the hypothesis is supported. The theory could need to be amended or abandoned if the predictions are not confirmed.

B) Why the results occurred may not yet be known.

C) Different people might have different explanations about why the results occurred.

D) The explanation would depend on if the hypothesis was supported.

These statements best describe why explanations of results might differ. Explanations are not solely dependent on differences in observations during experiments, and they are not all the same when they are about similar topics. Additionally, explanations can vary depending on who is providing the explanation, as different people may have different perspectives, knowledge, and interpretations. Finally, an explanation would also depend on whether the hypothesis was supported or not, as the results may require a different explanation if the hypothesis was not supported.

Corrosion

Explanation:

Silver is known as a noble metal. Noble metals are those metals that are resistant to corrosion.

However, we can not say that silver is completely resistant to corrosion because silver can corrode when exposed to air and sulphur.

Exposure to air and  sulphur leads to the coating of the silver with a sulphide layer thereby making the metal to become tarnished and loose its metallic luster.

The correct option is (e) 0.389 moles.

The number of moles represented by 21.7 g fe 0.389 moles.

Solution:

(21.7g) x (1mol/55.85g) = 0.389 moles

The mole, represented by the symbol mol, is the fundamental SI unit of material quantity. The amount of a substance determines how many elementary entities of that substance are present in an object or sample. Since the SI fundamental units were revised in 2019, the mole is now exactly defined as 6.022140761023.

A food supply company produces Yellow-42 (from previous example) in 200-gram wholesale bottles. The grams of FeCl3 needed to produce one bottle of Yellow 42 is 303.638 grams.  The amount of NaOH needed to produce one bottle of Yellow 42 is 226.32 grams.

∴

Using the relation for the number of moles which is:

\(\mathbf{number \ of \ moles = \dfrac{mass }{molar \ mass}}\)

\(\mathbf{number \ of \ moles \ of \ Yellow \ 42 = \dfrac{200 g }{106.867 \ g/mol}}\)

\(\mathbf{number \ of \ moles \ of \ Yellow \ 42 =1.872 \ moles}\)

Now,

∴

Mass of FeCl₃ required = number of moles of  FeCl₃ × molar mass of FeCl₃

Mass of FeCl₃ required = 1.872 moles × 162.2 g/mol

Mass of FeCl₃ required = 303.638 grams

7.

Recall that:

Now, 1.872 moles of Fe(OH)₃ will require (3 × 1.872 moles of NaOH)

= 5.616 moles of NaOH

Thus, the amount of NaOH in grams, that will be needed to produce one bottle of Yellow 42 is:

= 5.616 moles × 40.3 g/mol (molar mass of NaOH)

= 226.32 grams of NaOH

8.

The company could set up this reaction in a way that ensures no iron (III) chloride is wasted in the reaction by using the concept of the stoichiometry of the reaction involved in the system and he should feed the reactant within the ratio of 1:3 for FeCl₃ and NaOH respectively.

C. If  blood pressure decreases, filtration in the kidneys decreases.

D. If more blood returns to the heart, the ventricles contract more forcefully to pump it out, and this raises blood pressure.

The maintenance of blood pressure is defined as the high use of sodium in your diet and the low use of potassium in your diet can cause hypertension. It is also important to use those foods which are free from fats. It is also important that we should use fruits, vegetables, and grains in excessive amounts for the maintenance of blood pressure and for a healthy diet.

High blood pressure 190/110 mm Hg can cause the main vital organs of the body like the brain, heart, and kidney too. There are three factors that contribute to blood pressure which are resistance, blood viscosity, and blood vessel diameter.

During a chemical reaction, the concentrations of the reactants and products reach a constant level when the reaction reaches equilibrium.

At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction, meaning that the concentrations of both the reactants and products remain constant. The equilibrium concentration of each product and reactant is determined by the reaction's equilibrium constant, which is unique for each reaction.
Hi! During a chemical reaction, the point at which the concentrations of the reactants and products reach a constant level is defined as "equilibrium."

When a sucrose, is added to a solvent, it affects the boiling point of the solvent. This phenomenon is known as boiling point elevation.

Given information,

Mass of water = 1 kg

Moles of sucrose = 2 mol

The boiling point elevation: ΔTb = Kb × m

Where:

ΔTb is the change in boiling point and Kb is the molal boiling point elevation constant, and m is the molality of the solute.

m = (number of moles of solute) / (mass of solvent in kg)

m = 2.0 mol / 1.0 kg = 2.0 mol/kg

The value of Kb for water is approximately 0.512 °C/m.

Now, (ΔTb):

ΔTb = Kb × m

ΔTb = 0.512 °C/m × 2.0 mol/kg

ΔTb = 1.024 °C

Therefore, when 2.0 mol of sucrose is added to 1.0 kg of water, the boiling point of the water will increase by approximately 1.024 °C.
