Which set of numbers gives the correct possible values of I for n=3?(0,1,2)
(0,1,2,3)
(-2,-1,0,1,2)
(-3,-2,-1,0,1,2,3)

Answers

Answer 1
Answer: Symbol "l" denotes orbital quantum number which describes the shape of the orbital. From the given choices, those are magnetic quantum numbers which denotes the number of orbitals which is often a range of values from negative to positive. 2l + 1 is the formula to know the number of orbitals. l = n -1, where n is principal quantum number. Therefore l = 2, MI = (-2, -1, 0, 1, 2) or 5 orbitals.

Explanation:

The longer the wire, the more resistance that there will be and heating a metal conductor makes it more difficult for electricity to flow through it.

how many grams of silver chromate will precipitate when 150 ml of 0.500 M silver nitrate are added to 100 mL of 0.400 M potassium chromate

Answers

Final answer:

When 150 ml of 0.500 M silver nitrate are added to 100 mL of 0.400 M potassium chromate, a silver chromate precipitate forms. Considering the stoichiometry of the reaction and the quantities of reactants, 24.88 grams of silver chromate will precipitate.

Explanation:

The subject of this question is based on precipitation reactions in Chemistry. Precipitation reactions occur when two solutions combine to form an insoluble solid known as a precipitate. The moles of silver nitrate present in a 150 mL of 0.500 M solution can be calculated using the formula Molarity = Moles ÷ Volume (in Litres).

Thus, Moles of AgNO3 = 0.500 M * 0.15 L = 0.075 mol AgNO3. According to the reaction equation 2AgNO3 + K2CrO4 → 2AgCrO4(precipitate) + 2KNO3, for every mole of K2CrO4, we have two moles of AgNO3. Thus, based on stoichiometry and the given quantities of the reactants, the limiting reactant will be AgNO3, and it will totally react and form the silver chromate precipitate. The moles of Ag2CrO4 formed would therefore also be 0.075 mol. To convert this into grams, we use the molar mass of Ag2CrO4, which is approximately 331.73 g/mol. Hence, grams of Ag2CrO4 = 0.075 mol Ag2CrO4 * 331.73 g/mol = 24.88 g Ag2CrO4.

Which term is defined as a measure of the average kinetic energy of the particles in a sample?(1) temperature (3) thermal energy
(2) pressure (4) chemical energy

Answers

Answer: The correct answer is Option (1).

Explanation:

Average kinetic energy is defined as the average of the kinetic energies that is associated to the particles of the sample which are in random motion.

Temperature is the measure of the average kinetic energy of the particles. Formula used for calculating the average kinetic energy is given by:

K=(3)/(2)(R)/(N_A)* T

where,

K = kinetic energy

R = Gas constant

N_A = Avogadro's constant

T = temperature

Kinetic energy is directly proportional to the temperature of the particle.

\text{Kinetic energy}\propto \text{Temperature}

As the temperature increases, the kinetic energy of the particles also increases and vice-versa.

Hence, the correct answer is option 1.
The answer is (1). Temperature is directly proportional to the average kinetic energy of the particles in any given sample of matter, and it is usually defined along those lines.
