Answer: During succession, new species move into an area and colonize it.

Explanation: Ecological succession refers to the process of change in the composition and structure of an ecosystem over time. It occurs due to the interactions between the biotic (living) and abiotic (non-living) components of an environment. As succession progresses, new species gradually establish and thrive in the area, leading to a change in the species composition. This process can occur over a long period of time, ranging from decades to centuries, depending on various factors such as environmental conditions and the specific type of succession.

Based on the rate of disappearance of HI, the rate of appearance of I₂ is 0.225 mol/L/s.

The rate of a reaction is the rate at which reactant molecules are converted to product or the rate at which product molecules are formed.

From the equation of the reaction, 2 moles of HI produces 1 mole of I₂.

The rate of disappearance of HI is -0.45 mol/L/s

The rate of appearance of I₂ will be 0.45/2 mol/L/s = 0.225 mol/L/s.

Therefore, the rate of appearance of I₂ is 0.225 mol/L/s.

Fractional distillation is the process used for separating components of crude oil. There are three processes. Evaporation, condensation and collection.

The first stage of separation of components of crude oil is evaporation. The crude oil is heated until it is evaporated completely. This vapor reaches the fractional column.

Fractional column is the most important part of fractional distillation apparatus. It is a long column which accepts the vapor of evaporated crude oil and has collection apparatus at different levels. As the vapor travels through the column, it condenses. The one with lower boiling point will condense first and then the next and condensation process goes on.

As each component is condensed, it is collected and processed to make different products.

So the main steps are evaporation, condensation and collection.

10.0 L volume will this gas sample occupy if the pressure is increased to 2. 00 atm.

Volume is a measure of the amount of space an object occupies. It is a three-dimensional measure, meaning that it takes into account length, width, and height. Volume is measured in cubic units, such as cubic meters (m³), cubic centimeters (cm³), cubic feet (ft³), and so on. Volume is an important concept in many scientific fields, such as chemistry, physics, and engineering.

The volume of the gas sample can be calculated using the ideal gas law equation: PV = nRT

where P is the pressure, V is the volume, n is the amount of substance, R is the ideal gas constant, and T is the temperature.

Since the temperature and amount of substance remain constant, we can rearrange the equation to solve for V: V = nRT/P

Plugging in the known values, we get:

V = (n)(0.0821 atm•L/mol•K)(298 K)/(2.00 atm)

V = 10.0 L

The reaction is endothermic and absorbed N2 and O2 are reactants while NO is a product

An endothermic reaction is a chemical reaction that absorbs heat from the surroundings, resulting in an increase in the system's internal energy.

In other words, the energy of the products is greater than the energy of the reactants, and the reaction requires an input of heat to proceed. Endothermic reactions are characterized by a decrease in temperature of the surroundings.

The closest to the partial pressure of O₂ after the system has reached equilibrium is 0.5 atm, because K is very large, nearly all the SO₂ is consumed before the system reaches equilibrium, but an excess amount of O₂  remains at equilibrium. the correct answer is B.

Chemical equilibrium is the condition in which the concentrations of the reactants and products are equal and have no further tendency to fluctuate over time, with no discernible change in the features of the system.

The equilibrium moves to the side of the reaction where there are less moles of gas as the pressure increases. When the pressure decreases, the equilibrium moves to favor the reaction that produces more gas molecules.

Partial pressure is inversely proportional to volume, according to the ideal gas law. Additionally, it correlates with both the temperature and the amount of moles.

Answer: As one atomic dipole nears another atom it will affect the electron density distribution, so for example if the slightly positive end of the atom is located next to another atom, it will attract the electron(s) in the other atom. A covalent bond happens when atoms share an electron between them. The other kind of bond is called ionic, and it happens when one atom gives an electron to another atom. These bonds are held together with electric forces. Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are different.

Explanation:

The empirical formula of the magnetite ore is FeO₂, which indicates that the ore contains one iron atom and two oxygen atoms in each molecule.

The empirical formula of the iron ore, magnetite, can be determined using the mass of iron and oxygen present in the sample. Given that 72.35 g of iron is obtained from 100.0 g of the ore, the mass of oxygen can be calculated by subtracting the mass of iron from the total mass of the ore:

Mass of oxygen = Total mass of ore - Mass of iron

Mass of oxygen = 100.0 g - 72.35 g

Mass of oxygen = 27.65 g

To determine the empirical formula, we need to convert the mass of iron and oxygen to moles and then find the simplest whole number ratio between them. The molar mass of iron is 55.845 g/mol and the molar mass of oxygen is 15.999 g/mol. Using these values, we can calculate the number of moles of each element:

Moles of iron = 72.35 g / 55.845 g/mol = 1.295 mol

Moles of oxygen = 27.65 g / 15.999 g/mol = 1.728 mol

Dividing each of these values by the smallest value (1.295 mol) gives us the simplest whole number ratio:

Moles of iron = 1.295 mol / 1.295 mol = 1

Moles of oxygen = 1.728 mol / 1.295 mol = 1.334

Rounding to the nearest whole number gives us the empirical formula FeO₂.
