What is the answer?

Answer:

15lb

Explanation:

A 15lb pound of turkey will thaw faster compared to 25lb because it's not only smaller but the weight of the turkey affects how temperature circulates throughout.

Hope this helps :)

The turkey weighing 15 lb will thaw faster as it has lesser mass, and required less time.

Thawing has been the process of warming up the substance for converting freezed to a soft liquid and solid. The time required for thawing has been proportional to the energy required to change the substance state.

The turkey has been given of weight 15 lb and 25 lb. The more the weight, there has been more energy has been required for thawing.

Thus, 15 lb turkey will thaw faster as compared to the 25 lb turkey.

Answer: If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapor as it gets warmer.

The water particles in a pot of boiling water are behaving very differently from the water particles in the steam above the pot.

The water particles in the pot are tightly packed together. They are constantly moving, but they are not free to move around as much as the water particles in the steam.

The water particles in the steam are much farther apart. They are also moving much faster than the water particles in the pot. This is because the steam has been heated to the boiling point, which means that the water molecules have enough energy to escape from the liquid state and become a gas.

Answer:

C.) 0.85m

Explanation:

If you moved it for 3 seconds and it went 0.65m then continued to move for another 0.20m you would just add the two numbers together.

0.65+0.20=0.85m

The volume percentage of 18 L of isopropanol in 45 L of water is 28.57%

Total solution = volume of water + volume of isopropanol

Total solution = 18L + 45L

Total solution = 63L

Volume of isopropanol = 18L

% volume of 18L isopropanol = 18/63 * 100

% volume of 18L isopropanol = 1800/63

% volume of 18L isopropanol = 28.57%

Hence the volume percentage of 18 L of isopropanol in 45 L of water is 28.57%

Answer:

1. D: melting point, boiling point, surface tension, and vapor pressure

2. I’m not too sure about the second one. Maybe D Mix ice with water until just before equilibrium is reached but some ice remains that is still melting. However I am unsure. So do not take my word for it

Explanation:

The properties that a student can design an investigation of the electrostatic forces between molecules in a substance are  melting point, boiling point, surface tension, and vapor pressure.

To determine the melting point of ice, which procedure would best help measure the melting point temperature is to Mix ice with water until equilibrium is reached but some ice remains that is still melting.

Intermolecular forces are regarded as the forces of attraction or repulsion that exist or act between close particles  of atoms, molecules, or ions.

The slow heating rate at the melting point is important in order to get an the measurement.

When an individual heat ice, its temperature often rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted.

Explanation: For example, the compound HCl (hydrogen chloride) is comprised for 2 different types of atoms: one hydrogen and one Chlorine. In order to fuse these two elements together to form a compound, they must bond in one of three ways- ionic, covalent or metallic

The two statements that are true are as follows:

Thus, the correct options for this question are A and C.

A chemical compound may be defined as a type of chemical substance that is mainly composed of many similar molecules that contain atoms of more than one chemical element. These atoms are typically held together by chemical bonds.

If you take the example of NaOH where you will find three elements such as sodium, oxygen, and hydrogen. Each of these chemical elements is held together by chemical bonds in order to form sodium hydroxide.

The atoms of sodium hydroxide would not change their chemical formula when it is present as a chemical compound.

The molar solubility of magnesium oxalate Mg(C2O4 ) in water is 9.3 x 10⁻³ mol/L. So, the correct option is D.

Molar solubility of a substance is defined as the number of moles of solute that can be dissolved to make one litre of a saturated solution.

Here,

The solubility product constant of magnesium oxalate, Ksp = 8.6 x 10⁻⁵

The reaction for dissociation of magnesium oxalate in water can be written as,

MgC₂O₄ + H₂O ⇆ Mg²⁺ + C₂O₄²⁻

Magnesium oxalate is a binary salt.

So,

The molar concentration of  Mg²⁺ = molar concentration of C₂O₄²⁻

[Mg²⁺] = [C₂O₄²⁻] = x

The solubility product constant of MgC₂O₄,

Ksp = [Mg²⁺] [C₂O₄²⁻]

Ksp = x²

Therefore,

Molar solubility of MgC₂O₄,

x = √Ksp

x = √8.6 x 10⁻⁵

x = 9.3 x 10⁻³ mol/L

Hence,

The molar solubility of magnesium oxalate Mg(C2O4 ) in water is 9.3 x 10⁻³ mol/L.

Answer:

B

Explanation:

Each chlorine atom has 7 valence electrons. One from each of the Chlorine atoms bonded with one Phosphorous atom, leaving the rest of the pairs, 3 pairs each adding up to six, unbonded

The Lewis dot model of a molecule ( Phosphorous Chloride ) is  each chlorine has three non-bonded pairs and one bonded pair of electrons. Therefore, option B is correct.

Lewis' model demonstrated that, as long as the opportunity cost of labor to the capitalist sector is low, low wages and poverty will continue to exist in a labor surplus economy.

The Richard Lewis model of cultural diversity proposes that all cultures can be divided into three categories: linear-active, multi-active, and reactive. The Lewis model is a triangle made up of these three distinctly different cultural groupings.

The diagrams known as Lewis structures, often referred to as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

Explanation:

Answer:

air is the option so yeah it's right

This problem is describing a gaseous system composed by 12.0 L of nitrogen and 4.00 L of dinitrogen monoxide at 250 K and 0.550 atm. In addition, it is asking for the entropy of the system assuming it is ideal and the volumes are additive; this means we can use the following equation for the entropy of the mixture:

[tex]S_{mix}=-n_{N_2}*R*ln(\frac{n_{N_2}}{n_{N_2}+n_{N_2O}} )-n_{N_2O}*R*ln(\frac{n_{N_2O}}{n_{N_2}+n_{N_2O}} )[/tex]

It means we need to calculate the moles of both gases, which can be obtained by using the ideal gas equation for the common T,P conditions and the volume of each gas:

[tex]n_{N_2}=\frac{PV_{N_2}}{RT} =\frac{0.550atm*12.0L}{0.08206\frac{atm*L}{mol*K}*250K} =0.322mol\\\\n_{N_2O}=\frac{PV_{N_2O}}{RT} =\frac{0.550atm*4.00L}{0.08206\frac{atm*L}{mol*K}*250K} =0.107mol[/tex]

Next, we recall the aforementioned equation for the calculation of the entropy and plug in the values:

[tex]S_{mix}=-8.3145\frac{J}{mol*K}[0.322mol*ln(\frac{0.322mol}{0.322mol+0.107mol} )+0.107mol*ln(\frac{0.107mol}{0.322mol+0.107mol} )]\\\\S_{mix}=2.00\frac{J}{mol*K}[/tex]
