Why do halogens get less reactive?
The halogens gets less reactive as we move down the group because the atomic mass will increases and the number of the electrons are increases.
The halogens get less reactive as we move top to bottom in the group in the periodic table as the atomic mass of the group 17 elements that is halogens will increases and as we move from from top to bottom in the periodic table the electrons are added and the number of electrons are increases.
This is reason , that the reactivity of the group 17 elements that is halogens will decreases as we move from top to bottom.

Is it true that only 2 ATP are formed during anaerobic respiration?
Pyruvate is converted to lactate in anaerobic conditions by anaerobic glycolysis. During anaerobic respiration, two ATP molecules are produced.
What is the primary step in glycolysis?
The method by which glucose is metabolized to produce energy is known as glycolysis. It generates water, ATP, NADH, and two pyruvate molecules. It doesn't need oxygen to happen because it happens in a cell's cytoplasm. Both in aerobic and anaerobic organisms, it happens.
How is glycolysis referred to?
Gustav Embden, Otto Meyerhof, & Jakub Karol Parnas identified the Embden-Meyerhof-Parnas (EMP) pathway, which is the most typical kind of glycolysis. The Entner-Doudoroff pathway and several heterofermentative & homofermentative pathways are examples of additional pathways that are included in the term "glycolysis."

Define corrosion and explain the different basis of tendency or resistance of different
metals to corrosion
Corrosion is the process of chemical or electrochemical attack of materials by their external environment.
The tendency/resistance of different metals to corrosion largely depends on the composition of the metal. Iron and steel corrode in the presence of oxygen due to oxidation, while some metals such as chromium, nickel and molybdenum provide a protective layer of oxide film on the surface of the metal which is then resistant to corrosion. Other metals such as aluminum and zinc form sacrificial oxide layers which corrode and protect the metal from becoming completely damaged.
Diatomic elements are important. what makes them different from other elemental substances?
Diatomic elements are molecules composed of two atoms of the same element covalently bonded together, as opposed to other elements which are composed of only one atom.
What is diatomic?Diatomic elements are those elements that exist in nature as molecules made up of two atoms. Examples of diatomic elements include oxygen (O2), hydrogen (H2), nitrogen (N2), fluorine (F2), chlorine (Cl2), and iodine (I2). These elements are the only elements that exist naturally as diatomic molecules.
This gives diatomic elements distinct properties compared to other elemental substances, such as having two different electron configurations, and having different spin states. Diatomic elements also have properties that are unique to them, such as having different boiling points, higher densities, and different reactivity. Additionally, diatomic elements are essential for life as many are used in crucial biochemical processes.

In a given reaction, the rate may be expressed as either the rate of formation of a product (X) or the rate of consumption of a reactant (Y). If the reaction is proceeding in the forward direction, the rate of formation of the product (X) will be positive and the rate of consumption of the reactant (Y) will be negative.
This means that X is being produced at a faster rate than it is being consumed and Y is being consumed at a faster rate than it is being produced.

The action "Heat energy was retained and water vapor condensed." characterized Earth's earliest atmosphere (atmosphere I)
Earth's earliest atmosphere, also known as atmosphere I, was primarily composed of methane, ammonia, and water vapor. The heat energy from the young Earth's molten surface caused these gases to rise and cool, leading to the condensation of water vapor and the formation of oceans. This process is known as the "greenhouse effect," as the retained heat energy allowed for the formation of a hospitable environment for the emergence of life. Ultraviolet light from the sun also played a role in the formation of the atmosphere by breaking down water vapor into hydrogen and oxygen, but this was not the primary process that characterized atmosphere I.

x has the values (2.14 + √(23.288)) / 9.56 and (2.14 - √(23.288)) / 9.56.
What Is a Quadratic Equation?Quadratic equations are the degree two, one-variable polynomial equations of the form f(x) = ax^2 + bx + c = 0 with a, b, c, and R R and a 0 being the variables. In its most basic form, it is a quadratic equation where "a" denotes the leading coefficient and "c" is the absolute term of f(x). The values of x that satisfy the equation (, ) are the quadratic equation's roots.
The name "quadratic equation" is for what?Intricate relationships exist between square and quadrangle (another name for rectangle) difficulties and quadratic equations.
The Latin term quadratus, which means square, is where the word "quadratic" originates.
The quadratic formula or factoring can be used to get the solution to the problem 4.78x^2-2.14x-1.60=0.
x = (-b (b^2 - 4ac)) / (2a) where a = 4.78, b = -2.14, and c = -1.60 is the quadratic formula.
Plugging in the values we get:
x = (-(-2.14) ± √((-2.14)^2 - 4(4.78)(-1.60)) ) / (2(4.78))
x = (2.14 ± √(4.6016 + 18.688)) / 9.56
x = (2.14 ± √(23.288)) / 9.56
So the two values of x are:
x = (2.14 + √(23.288)) / 9.56 and x = (2.14 - √(23.288)) / 9.56

What is the relative rate of diffusion of CH4 and NO2?
Answer:
=32×1632×√1632=34√2.
Explanation:
Container A holds 747 mL747 mL of ideal gas at 2.90 bar2.90 bar . Container B holds 119 mL119 mL of ideal gas at 4.30 bar4.30 bar . If the gases are allowed to mix together, what is the partial pressure of each gas in the total volume
the partial pressure of gas A in the total volume is 3.57 bar, and the partial pressure of gas B in the total volume is 0.70 bar.
When the gases are allowed to mix together, the total pressure of the mixture is equal to the sum of the partial pressures of each gas. The partial pressure of each gas is equal to the product of the total pressure and the mole fraction of that gas. To find the mole fraction of each gas, we first need to find the number of moles of each gas. The number of moles of gas in container A is given by PV/RT where P is the pressure, V is the volume, R is the ideal gas constant and T is the temperature.
n_A = (2.90 bar * 747 mL) / (8.314 J/molK * (273.15 + 23)) = 0.0295 mol
The number of moles of gas in container B is given by PV/RT
n_B = (4.30 bar * 119 mL) / (8.314 J/molK * (273.15 + 23)) = 0.0045 mol
The total number of moles of gas in the mixture is the sum of the number of moles of gas in container A and container B.
n_total = n_A + n_B = 0.0295 mol + 0.0045 mol = 0.0340 mol
The mole fraction of gas A in the mixture is the number of moles of gas A divided by the total number of moles of gas.
x_A = n_A / n_total = 0.0295 mol / 0.0340 mol = 0.8735
The mole fraction of gas B is
x_B = n_B / n_total = 0.0045 mol / 0.0340 mol = 0.1324
The partial pressure of gas A is equal to the total pressure multiplied by the mole fraction of gas A.
P_A = (0.8735) * (2.90 bar + 4.30 bar) = 3.57 bar. The partial pressure of gas B is equal to the total pressure multiplied by the mole fraction of gas B. P_B = (0.1324) * (2.90 bar + 4.30 bar) = 0.70 bar
So the partial pressure of gas A in the total volume is 3.57 bar, and the partial pressure of gas B in the total volume is 0.70 bar.

Helium: The new volume of the balloon is 0.6182 L.
Colorless, odourless , tasteless, inert, non-toxic helium is a monatomic gas. It is the lightest element in the periodic table and the second most abundant element in the universe.
The new volume of the balloon can be calculated using the ideal gas law, which states that PV = nRT, where P is the n represents the number cubic moles of gas, V represents the volume, R is the real gases constant, and the temperature is T.
First, we need to calculate the number of moles of helium in the balloon after the additional 0.670 grams have been added:
n = 0.670 g He/4.003 g/mol = 0.167 mol
The total number of moles in the balloon is now 0.267 mol. We can use the ideal gas law to calculate the new volume:
