The symptom substitution conflict highlights a disagreement between psychoanalytic and behavioral theories concerning the causes of behavior.

This is a theory that discusses the nature and development of human personality. The main elements in this theory are motivation, emotions and other aspects of personality.

The basis of psychoanalytic theory is to assume that personality will begin to develop when conflicts occur from the psychological aspects themselves. These symptoms usually occur in children or at an early age. Then Sigmund Freud's opinion about human personality is based on the experiences of his patients.

Sigmund Freud is a psychological scientist known for his ideas about human personality based on the analysis of his dreams, and his extensive reading of various scientific and human literature.

The minimum amount of butane that could be left over by the chemical reaction would be 10.12 grams.

The equation of the reaction would be as follow:

[tex]2C_4H_{10} + 13O_2 -- > 8CO_2 + 10H_2O[/tex]

Mole ratio of butane to oxygen = 2:13

Mole equivalence of 30.8 g of butane = 30.8/58.12 = 0.5299 mol

Mole equivalence of 74 g of oxygen = 74/32 = 2.3125 mol

From the mole ratio, the actual amount of butane required for 2.3125 mol of oxygen:

2/13 x 2.3125 = 0.3558 mol

Excess mol of butane = 0.5299 - 0.3558 = 0.1741 mol

Mas of 0.1741 mol butane = 0.1741 x 58.12

                                           = 10.12 grams

In other words, the minimum mass of butane that could be left over by the chemical reaction is 10.12 grams.

39.8 grams of mercury, hg are in 1.19 x 10^23 atoms of mercury.

Explain about atoms of mercury?

Atoms of mercury are the smallest and most basic particles of the element mercury. They consist of a single proton, a single electron, and no neutrons. The proton and electron of the mercury atom are held together by the strong nuclear force, which is the strongest force in the universe. The element mercury has an atomic number of 80, meaning that it has 80 protons and 80 electrons. Mercury atoms have a diameter of about 0.2 nanometers, which is about one-millionth the size of a grain of sand. They are so small that they can only be seen with a powerful microscope.

Step 1: Convert atoms to moles

One mole of any substance contains Avogadro's number of atoms (NA), which is defined as 6.022 x 10^23 atoms. Hence, the number of moles can be calculated as follows:

moles = number of atoms / Avogadro's number

For 1.19 x 10^23 atoms of mercury, the number of moles would be:

moles = 1.19 x 10^23 atoms / 6.022 x 10^23 atoms/mole = 0.1983 moles

Step 2: Convert moles to grams

The molar mass of a substance is defined as the mass in grams of one mole of the substance. For mercury, the molar mass is 200.59 g/mol.

To convert the number of moles to grams, we simply multiply the number of moles by the molar mass:

grams = moles x molar mass

For 0.1983 moles of mercury, the number of grams would be:

grams = 0.1983 moles x 200.59 g/mol = 39.8 grams

Therefore,39.8 grams of mercury.

A semipermeable membrane is placed between the following solutions. Solution D will increase in volume.

What is volume?

Volume is a measure of the amount of space an object or substance occupies. It is most commonly measured in cubic units, such as cubic inches or cubic centimeters. Volume is a calculation of the 3-dimensional amount of space enclosed by an object or substance, and is typically found by calculating the area of one side of the object or substance and multiplying it by the object's height. Volume can be used to measure solid objects, liquids, and gases. It can also be used to measure the amount of material present in a space, such as the amount of water in a swimming pool or the amount of air in a room.

This is because the semipermeable membrane will allow the solvent (water) to move from the solution with a lower concentration of solutes (solution C) to the solution with a higher concentration of solutes (solution D), increasing the volume of solution D.

The given statement is true. When calculating the volume of a compound, the molar mass must be used instead of the equation.

Additionally, the equation only works for substances with a constant density, as variations in temperature and pressure can cause the density of a substance to change. In such cases, it is important to adjust the equation accordingly to account for these changes.

To adjust the equation for temperature and pressure variations, one must use the ideal gas law, which states that the pressure of a gas is directly proportional to its temperature and molar mass. This means that if the temperature and/or pressure of a substance is increased, the molar mass must also be increased to compensate for the change in the density.

A rate of reaction is the speed at which a chemical reaction takes place. It is usually expressed as the change in the concentration of a reactant or product per unit time. The rate of a reaction is determined by many factors, including the physical state of the reactants, the temperature, the concentration of the reactants, the presence of a catalyst, and the surface area of the reactants that are in contact with each other.
