Answer 2

For calculating mean value, add up all of the values then divide by the number of them. 815/9 is about 90.6

What is mean value?

The mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations), the geometric mean, and the harmonic mean.

Moreover, the mean can be used to represent the typical value and therefore serves as a yardstick for all observations. For example, if we would like to know how many hours on average an employee spends at training in a year, we can find the mean training hours of a group of employees.

Hence, the mean can be calculated only for numeric variables, no matter if they are discrete or continuous. It's obtained by simply dividing the sum of all values in a data set by the number of values.

A formic acid buffer solution contains 0. 20 m h c o o h hcooh and 0. 24 m h c o o − hcoox−. the pka of formic acid is 3. 75. what is the ph of the buffer?

Answers

A buffer solution contains an equivalent amount of acid and base. The pH of the solution with an acid dissociation constant (pKa) value of 3.75 is 3.82.

What is pH?

The amount of hydrogen or the proton ion in the solution is expressed by the pH. It is given by the sum of pKa and the log of the concentration of acid and bases.

Given,

Concentration of salt [HCOO⁻] = 0.24 M

Concentration of acid [HCOOH] = 0.20 M

The acid dissociation constant (pKa) = 3.75

pH is calculated from the Hendersons equation as,

pH = pKa + log [salt] ÷ [acid]

pH = 3.75 + log [0.24] ÷ [0.20]

= 3.75 + log (1.2)

= 3.75 + 0.079

= 3.82

Therefore, 3.82 is the pH of the buffer.

What is the ph of a solution which is 0. 025 m in weak base and 0. 039 m in the conjugate weak acid ( a = 7. 1 × 10−6)?

Answers

The pH of the solution is 4.96.

pH measures the amount of hydrogen and hydroxide ions in a solution and shows how acidic or alkaline it is.

Weak bases are the solutions to substances that do not dissociate completely in water. Conjugate acids are the product formed by the base and have a difference of one proton.

Using the base dissociation constant, Ka

pKa can be calculated as,

[tex]pKa = - log (Ka)[/tex]

       [tex]= - log (7.1 * 10^-6)[/tex]

       [tex]= 5.15[/tex]

0. 025 M in the weak base and 0. 039 M in the conjugate weak acid.

Therefore, a weak base and its conjugate acid are present in equal proportions in buffer solution. As we are aware, the Henderson-Hasselbalch equation can be used to determine the pH of a buffer solution that comprises a weak base and its conjugate acid.

[tex]pH = pK + log [\frac{A^-}{HA} ]\\[/tex]

b) If a mole of sugar costs 90 cents, what is the value of the sugar in a can of pop (3 marks)?

c) How many particles of sugar are there in the pop (3 marks)?

Answers

The number of sugar particles is 7.4 * 10^22 particles.

What is the mole?

The mole is used to describe the amount of substance. The idea was first introduced by Professor Avogadro and the number of particles that constitute one mole of a substance was said to be 6.02 * 10^23 particles in a mole.

Thus;

Molar mass of sugar = 342 g/mol

Number of moles of sugar = 42 grams/342 g/mol = 0.123 moles

Now;

If 1 mole of sugar costs 90 cents

0.123 moles of sugar costs 0.123 moles *  90 cents/1 mole

= 11 cents

Now we know that;

1 mole of sugar contains  6.02 * 10^23 particles

0.123 moles of sugar contains 0.123 moles *  6.02 * 10^23 particles / 1 mole

A sample of gas has an initial volume of 3.97 L at a pressure of 709 mmHg . If the volume of the gas is increased to 5.36 L , what is the pressure

Answers

Answer:

525 mmHg

Explanation:

If all other variables are held constant, you can find the pressure using Boyle's Law. The equation looks like this:

P₁V₁ = P₂V₂

In this equation, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. You can plug the given values into the equation and simplify to find "P₂".

P₁ = 709 mmHg                      P₂ = ? mmHg

V₁ = 3.97 L                              V₂ = 5.36 L

P₁V₁ = P₂V₂                                                         <----- Boyle's Law

(709 mmHg)(3.97 L) = P₂(5.36 L)                      <----- Insert values

2814.73 = P₂(5.36 L)                                          <----- Simplify left side

Which reaction most accurately represents the dissociation of nitrous acid (hno2) in water?

Answers

When nitrous acid (HNO₂) dissociates in water (H₂O), the reaction that best captures this process is:

                HNO₂ (aq.) + H₂O ↔  H₃O⁺ (aq.) + NO₂⁻ (aq.)

How does one know about HNO₂?

The chemical designation for nitrous acid is HNO₂, and it is a monoprotic acid. Three elements—hydrogen(H), oxygen(O), and nitrogen(N), all compose it. It is highly fragile in nature and only occurs in solutions. It is employed to convert amines into diazonium salts.

Is HNO₂ a basic or an acid?

Acidity is assigned to nitrous acid (HNO₂). Once dissolved in water, it gives out H+ ions. Acid is a chemical that produces H+ ions in a water-based solution or gives the protons to other molecules.

Thus, HNO₂ is acid because it causes a mixture of water to contain H+ ions. In a 10 mM concentration, it possesses a pH of 2.67.

Why is an aqueous solution of potassium hydroxide an unsuitable medium for effecting the base promoted elimination of the E2 reaction procedure

Answers

The potassium hydroxide is an unsuitable medium because an aqueous solution medium is highly polar in nature, so there will be a high tendency for carbonation to be formed and prefer substitution reaction rather than an elimination reaction.

The potassium hydroxide is an unsuitable medium for effecting the base-promoted elimination due to the fact that alkoxide anions aren't only more basic than the pure hydroxyl group, but they may be also bulkier. The higher bulkiness makes it a worse nucleophile than hydroxyl and the higher basicity makes it better at E2 eliminations.

A substitution reaction is a form of Chemical reaction in which the functional group of 1 chemical compound is substituted by means of any other group or it's miles a reaction that involves the substitute of one atom or a molecule of a compound with another atom or molecule.

Carbonation is the chemical reaction of carbon dioxide to provide carbonates, bicarbonates, and carbonic acid. In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids.

The respiratory acidosis occurs when breathing out does not get of enough [tex]CO_{2}[/tex] . The increased [tex]CO_{2}[/tex] that  remains results in overly acidic blood. This can results from respiratory problems.

What would happen if N₂ were added to N₂(g) + O₂(g) = 2NO(g) at
equilibrium?
O A. More O2 and NO would form.
OB. More NO would form.
C. More N₂ and O2 would form.
O D. Keq would decrease.

Answers

Answer:

B.) More NO would form.

Explanation:

If the amount of N₂ increases, the equilibrium will be out of balance. In order to restore the balance, the reaction will shift to the products side. As such, the amount of NO will increase.

According to Le-chatlier principle, if N₂ is added to the reaction system, then more NO will be produced so as to decrease the amount of N₂.

What is Le-Chatlier principle ?

The Le Chatlier's Principle, also known as the Le Chatlier's Law, is a principle in chemistry that states that when a system at equilibrium is subjected to a change in conditions, such as temperature, pressure, or concentration, the system will adjust its equilibrium position to counteract the change and restore equilibrium.

In other words, if a system is disturbed from its equilibrium state, it will try to minimize the effect of the disturbance by shifting the equilibrium position in a direction that partially offsets the disturbance.

If any substance is added to the system, the equilibrium will shift to the direction in which the added substance is consumed. Hence, as  N₂ is added to the system, it will consumed to give the product NO.

What is a synthesis reaction?A synthesis reaction is a classification of responses in which multiple reactants connect to form a single product. If we observe the equation, no replacement is accepted place hence, single and double replacements are wrong choices.In decomposition reaction there is only one reactance which gets disintegrate and form multiple product.Synthesis reactions are reactions that occur when two additional atoms or molecules interact to form a separate molecule or compound. Most of the time, when a synthesis reaction occurs, energy is discharged and the reaction is exothermic. However, an endothermic consequence is also feasible.

Thomson offered an explanation for the structure of the atom. Rutherford, along with two of his associates Hans Geiger and Ernest Marsden, performed an experiment in which an extremely thin metal foil was fired with a beam of alpha particles. The results of the experiment were recorded accurately by another scientist who observed the frequency of alpha particles that passed through the foil unobstructed.Use information from the passage to justify whether the characteristics of reliable scientific explanations are present in the development of the atomic theory.

Whole grains contain the entire grain kernel, which includes the outermost layer the inner layer, and the smallest part of the grain. These are the bran, germ and endosperm. Together they make a whole grain. Whole grains, which include whole-wheat flour, whole cornmeal, oatmeal, and brown rice are great nutritional choices. Refined grains such as white bread and white rice, are not as nutritionally powerful for they lack the vitamins and fiber that the two outer layers of grain provide. In order to get the most out of your daily grain consumption choose oatmeal, popcorn, or whole-grain crackers. A general recommended daily intake of grains amounts to about one cup of cereal at breakfast two slices of whole grain bread at lunch, and one cup of pasta or rice at dinner.
