Both transition metals and alkali metals are good conductors of heat and electricity, react with water, and are easily oxidized.
What are alkali metals and transition metals?The alkali metals are elements of group 1 which are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). They are also known as the s-block elements because they have their outermost electron in an s-orbital.
The alkali metals are shiny, soft, highly reactive metals and readily lose their outermost electron to create cations with charge +1. They can tarnish rapidly in the air due to oxidation by atmospheric moisture and oxygen.
Transition elements or transition metals are elements that have partially filled d-orbitals. An element having a d-subshell that is partially filled with electrons or can form stable cations with an incompletely filled d orbital.
Any element present in the d-block of the modern periodic table which consists of groups 3 to 12, is considered to be a transition element. For example, the mercury in the +2 oxidation state, corresponds to an electronic configuration of (n-1)d¹⁰. Many paramagnetic compounds are formed by transition metals because they have unpaired electrons in the d orbital.

calculate the vapor pressure of a solution of 0.300 mol fraction of toluene and 0.700 mol fraction of cyclohexane at 32oc and determine whether the solution will boil. the vapor pressure of pure toluene is 40.2 torr and that of cyclohexane is 125 torr at 32oc
The Vapour pressure of the solution is 99.56 torr
The saturated vapour pressure of the solution maybe lower then the pressure of pure solvent in solution. It is equal to the vapour pressure of the pure solvent at the same temperature scaled by mole fraction of solvent stated by Rault's Law.
P(solution) = mol fraction of solvent × P° ( solvent)
given, pressure of pure toulene = 40.2 torr
pressure of pure cyclohexane = 125 torr
∴ P (solution) = 0.3 × 40.2 + 0.7 × 125
P (solution) = 99.56 torr

Alkaline earth metals are part of the eighth group and are known to exist in two groups.
Consequently, the element's atomic number will be 120.
What is meant by atomic number?The quantity of protons in an atom's nucleus is known as the atomic number. An element's identity is determined by its proton count (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
A chemical element's atomic number is its position in the periodic system, which places the elements in ascending order of the number of protons in their nuclei. As a result, the atomic number is also determined by the number of protons, which is always equal to the number of electrons in a neutral atom.

The balloon and the comb definitely have the same electrical charge. Option 2.
Like charges repelAccording to the law of attraction in physics, like charges repel while unlike charges attract.
Going by this law:
positive and positive will repelnegative and negative will repelpositive and negative will attract.In other words, if 2 objects that have the same charges are brought close to each other, there will be a repulsion. If the 2 objects are of different charges, there will be an attractive force between them.
The students observed that the comb repelled the balloon. The implication is that the comb and the balloon are of the same charge.
This is logical considering the fact that both objects were rubbed against hair. They got their charges during the process of rubbing. An electrostatic force is generated that moves electrons from the hair to the two objects.
Thus, both the balloon and the comb are negatively charged and will, therefore, repel each other.

why there is only one sodium ion for every chlorine ion, while there are two potassium ions for every oxygen ion?
There is only one sodium ion for every chlorine ion due to its valency.
The number of electrons that an atom needs to lose or gain in order to achieve a stable electron configuration i.e the octet of an element is known as the valency of an element, which serves as a gauge of that element's potential for combining.
The valency of Sodium (Na) is 1 and that of chlorine (Cl) is also one. therefore they combine to form a stable compound. The same rule follows in the compound formed by Potassium (K) and Oxygen(O) also. The valency of oxygen is 2 which means that it should be surrounded by 2 potassium ions to provide electrons to fulfill both the elements' octets.

To find the order of a reaction with respect to one reactant, you will monitor the Percentage as the reactant of product is changed.
To determine the reaction order from experimental data, either the differential rate law or the integrated rate law can be used. In the rate law, the exponents are frequently positive integers: 1 and 2 or even 0. As a result, the reactions in each reactant are of zeroth, first, or second order. Changes in the concentration of the reactants or products can be used to calculate the rate. changes in reactant or product mass or volume If the reaction is the result of multiple reaction steps with different orders, the order of the reaction can be changed by adjusting the reagent concentration. Because the order is often ruled by the slowest reaction, you can manipulate the relative reaction speed by varying the concentrations.

selective analysis of an analyte and internal standard yielded detector responses of 3.47 and 5.23 respectively when each had a concentration of 1.00 ppm. five ml of an unknown analyte solution were mixed with 1 ml of 5.00 ppm internal standard and then diluted to a total of 10 ml. the detector responses for analyte and internal standard for this mixture were 4.26 and 2.43. calculate the concentration of the analyte in the unknown solution. report your answer in ppm.
By calculating the response factor for the internal standard first, we can calculate that the concentration of the unknown analyte sample is 2.64 ppm.
When solving problems like this, we need to calculate the appropriate response factor:
A(X) / C(X) = F * A(S) / C(S)
A(X) - response for the analyte (3.47)
C(X) - concentration of the analyte (1 ppm)
F - response factor
A(S) - response for the internal standard (5.23)
C(S) - concentration of the internal standard (1 ppm)
F = A(X) * C(S) / (C(X) * A(S)
F = 3.47 * 1 ppm / (5.23 * 1 ppm)
F = 0.663
Now we can use this in the second calculation to obtain the concentration of the analyte in the sample. One thing to note is that in second measurement 1 mL of a 5.00 ppm internal standard was diluted to 10 mL, so the concentration of the internal standard is actually 5.00 ppm / 10 = 0.500 ppm.
4.26 / C(X) = 0.663 * 2.43 / 0.500 ppm
C(X) = 4.26 * 0.500 ppm / (0.663 * 2.43)
C(X) = 1.32 ppm
Because 5 mL of the analyte solution were diluted to 10 mL, the concentration is actually 2 * 1.32 ppm = 2.64 ppm.

you need to prepare 1 l of the acetic acid/acetate buffer. you decided to mix 300 ml of 0.45 m acetic acid acid and 100 ml of 0.65 m naoh plus water to a final volume of one liter. the pka of acetic acid is 4.75. 1. calculate the ph of your buffer solution. 2. naoh is not the conjugate base to acetic acid. explain why you can use naoh to make an effective acetate buffer.
The pH of buffer solution is 4.72.
1) Molarity of acetic acid = 0.45 M
The volume of acetic acid = 300 ml
Molarity of NaOH = 0.65 M
Volume of NaOH = 100 ml
An acidic buffer solution is calculated by using Henderson's equation:
pH = pKa + ㏒[salt] / [acid]
where pKa = 4.75
pH = 4.75 + ㏒[0.065M] / [0.07M]
pH = 4.75 + ㏒(0.929)
pH = 4.75 - 0.03
pH = 4.72
Therefore, the pH of the buffer solution is 4.72.
2) NaOH is not the conjugate base to acetic acid. As we know NaOH is a strong base and acetic acid is a weak acid. Thus, an acid-base reaction occurs between acetic acid and NaOH, thus forming CH₃COONa, which is the conjugate base of acetic acid.
Acidic buffer solution is formed by mixing of weak acid and its conjugate salt of strong base. Thus, NaOH acts as limiting reactant and only CH₃COOH and CH₃COONa is present in solution. Thus, CH₃COOH is weak acid and CH₃COONa is its conjugate salt of strong base forms buffer solution. In the reaction of NaOH and CH₃COOH, NaOH gets completely reacted and forms CH₃COONa. Thus, NaOH is added to make an effective acetate buffer.

Substituting all the given values, we get
(P₁×M₁)÷T₁=(P₂×M₂)÷T₂
(P₁×20)÷303=(1.0 ×28)÷293
P₁=1.44atm
Therefore, the pressure that will be required for neon at 30°C to have the same density as nitrogen at 20°C and 1.0 atm is 1.44atm.
