According to Maslow, humans devote all their efforts to satisfying lower-level needs until they are met. Only when these needs are met can people focus their attention on satisfying the next level of needs.

Maslow refers to Abraham Maslow, an influential psychologist known for his theory of human motivation and the hierarchy of needs. Maslow's hierarchy of needs is a psychological theory that explains human motivation and the progression of needs from basic survival to higher-level psychological fulfillment.

According to Maslow, human needs can be organized into a hierarchical structure, with lower-level needs needing to be satisfied before higher-level needs become motivating factors. The hierarchy consists of five levels:

Physiological Needs: These are the most basic needs necessary for survival, such as food, water, shelter, and sleep. These needs must be fulfilled before higher-level needs become relevant.

According to Maslow, humans devote all their efforts to satisfying lower-level needs until they are met. Only when these needs are met can people focus their attention on satisfying the next level of needs. These lower-level needs include physiological needs such as food, water, and shelter, as well as safety needs such as feeling secure and free from harm. Once these needs are satisfied, individuals can then focus on satisfying higher-level needs such as social belonging, self-esteem, and ultimately self-actualization.

The trend in ionization energies as you go down a group is C. Going down the group Ionization energies decrease as the atomic radius increase.

Ionization energy is the energy required to remove an electron from a neutral atom in gaseous form. Also as with the atomic radius, the periodicity of this one element also has the following tendencies:

In a group from top to bottom, the ionization energy of an element decreases because the atomic radius increases, so that the attraction of the nucleus to the outermost electrons becomes weaker and the ionization energy decreases.

In one period, the ionization energy of the elements increases from left to right because the atomic radius is getting smaller, so that the attraction of the nucleus to the outermost atom is getting stronger and the ionization energy is increasing.

The kinetic energy is 0.5177 × 10⁻²¹ J more at 50°C compared to 25°C.

The average kinetic energy of a molecule is directly proportional to the absolute temperature of a gas.

KE = ( 3/2 ) ( R / Nₐ ) T

Where T is the temperature of the molecule, R is the gas constant, and Nₐ is Avogadro's number.

Now, R = 8.314 J/mol.K

Avogadro's number, Nₐ = 6.022 × 10²³ atoms/ mol

The average kinetic energy at 50° C is:

T = 50° C = 323 K

KE₁ = ( 3/2 ) × ( R / Nₐ ) × T₁

KE₁ = ( 3 × 8.314 × 323 ) / ( 2 × 6.022 × 10²³ )

KE₁ = 668.90 × 10⁻²³ J

KE₁ = 6.6890 × 10⁻²¹ J

The average kinetic energy at 25°C is:

KE₂ = ( 3/2 ) × ( R / Nₐ ) × T₂

KE₂ = ( 3 × 8.314 × 298 ) / ( 2 × 6.022 × 10²³ )

KE₂ = 617.13 × 10⁻²³ J

KE₂ = 6.1713 × 10⁻²¹ J

Now,

The average kinetic energy of the molecules at 50° C compared to 25° C is:

KE = KE₁ - KE₂

KE = 6.6890 × 10⁻²¹ - 6.1713 × 10⁻²¹

KE = 0.5177 × 10⁻²¹ J

Hence, the average kinetic energy is 0.5177 × 10⁻²¹ J more at 50° C compared to 25° C.

When 7.00 mol of NaOH reacts with 2.5 mol of CaBr2, 5.0 mol of NaBr will be produced.

To determine the number of moles of NaBr produced, we need to look at the balanced chemical equation for the reaction between NaOH and CaBr2.

The balanced equation is:

2NaOH + CaBr2 -> 2NaBr + Ca(OH)2

According to the balanced equation, 2 moles of NaOH react with 1 mole of CaBr2 to produce 2 moles of NaBr.

Given that 7.00 mol of NaOH and 2.5 mol of CaBr2 are available, we can determine the limiting reactant. The limiting reactant is the one that is completely consumed first and determines the maximum amount of product that can be formed.

To find the limiting reactant, we compare the moles of each reactant to their stoichiometric coefficients in the balanced equation:

For NaOH: 7.00 mol NaOH * (1 mol CaBr2 / 2 mol NaOH) = 3.50 mol CaBr2

For CaBr2: 2.5 mol CaBr2

The limiting reactant is CaBr2 since it has the smaller amount. Therefore, 2.5 mol of CaBr2 will react completely.

From the balanced equation, we know that 2 moles of NaBr are produced for every 1 mole of CaBr2. Therefore, the number of moles of NaBr produced will be:

2.5 mol CaBr2 * (2 mol NaBr / 1 mol CaBr2) = 5.0 mol NaBr

Answer:

The name of the potassium salt of m- ethyl benzoic acid is potassium m- ethyl benzoate. The correct option is (b).

Potassium m- ethyl benzoate is formed when m- ethyl benzoic acid reacts with potassium hydroxide in an aqueous solution. This reaction is an example of an acid-base reaction, where the acid (m- ethyl benzoic acid) donates a proton (H+) to the base (potassium hydroxide) to form an ionic salt. The general equation for this reaction is:


m- ethyl benzoic acid + potassium hydroxide → potassium m- ethyl benzoate + water


The m- ethyl group of m- ethyl benzoic acid replaces the hydrogen atom in the carboxyl group of the acid. This produces an anion of m- ethyl benzoate, which is then balanced out by the positively charged potassium ion (K+).


Potassium m- ethyl benzoate is an odorless white crystalline solid. It is soluble in water, alcohol, and other organic solvents, and it is used in the synthesis of various drugs and chemicals.

Therefore, the correct answer is (b).

Explanation:

We have to use the formula;

0.693/t1/2 =2.303/t log Ao/A

Where;

t1/2= half-life of phosphorus-32= 14.3 days

t= time taken for the activity to fall to 7.34% of its original value

Ao=initial activity of phosphorus-32

A= activity of phosphorus-32 after a time t

Note that;

A=0.0734Ao (the activity of the sample decreased to 7.34% of the activity of the original sample)

Substituting values;

0.693/14.3 = 2.303/t log Ao/0.0734Ao

0.693/14.3 = 2.303/t log 1/0.0734

0.693/14.3 = 2.6/t

0.048=2.6/t

t= 2.6/0.048

t= 54 days

Answer:

\(\boxed {\boxed {\sf V_2=75 \ mL}}\)

Explanation:

Since the pressure is constant, the only variables we need to work with are temperature and volume. We will use Charles's Law, which states the volume of a gas is directly proportional to the temperature. The formula is:

\(\frac{V_1}{T_1}=\frac{V_2}{T_2}\)

Originally, the gas was 50 milliliters at 20 degrees celsius. Substitute these values into the left side of the equation.

\(\frac{50 \ mL}{20 \textdegree C}=\frac{ V_2}{T_2}\)

We don't know the volume of the new gas, but we know the temperature was changed to 30 degrees celsius.

\(\frac{50 \ mL}{20 \textdegree C}=\frac{ V_2}{30 \textdegree C}\)

Since we are solving for the new volume, we must isolate the variable. It is being divided by 30 °Cand the inverse of division is muliplication. Multiply both sides by 30 °C.

\(30 \textdegree C*\frac{50 \ mL}{20 \textdegree C}=\frac{ V_2}{30 \textdegree C}* 30 \textdegree C\)

\(30 \textdegree C*\frac{50 \ mL}{20 \textdegree C}= V_2\)

The units of degrees celsius cancel, so we are left with milliliters as the units.

\(30*\frac{50 \ mL}{20}= V_2\)

\(\frac{1500 \ mL}{20}= V_2\)

\(75 \ mL=V_2\)

The new volume of the gas is 75 milliliters.
