Answer: The product of beta decay of the Manganese isotope 57Mn is 57^Fe.

Explanation:

The outcome of the beta decay of 57Mn isotope is 57Fe. This happens because during beta decay, a neutron in the nucleus turns into a proton and emits an electron, which increases the atomic number of the nucleus by one, but keeps the atomic mass the same.

1.81 moles are in 500 grams of BeCr2O7.

Molar mass of BeCr2O7 = 276.095 g/mol

500 g / 276.095 g/mol = 1.81 moles

What is moles?

Moles is a unit used to measure the amount of a substance. It is defined as the amount of a substance that contains the same number of atoms, molecules, ions, or electrons as the number of atoms in 12 grams of carbon-12 (C-12). This means that one mole of any substance will contain the same number of atoms, molecules, ions, or electrons as one mole of C-12. Moles are used in chemistry to measure the quantity of a substance. For example, when a chemist mixes two solutions together, they can use moles to calculate the amount of each substance that was mixed.

In the fields of organic and biochemistry, a side chain is a chemical group that is connected to the "main chain" or backbone of a molecule and serves as an attachment point for other parts of the molecule. A molecule's side chain is a hydrocarbon branching element that is coupled to a larger hydrocarbon backbone. This element is known as the side chain. There is only one amino acid on this list that possesses a R group that is able to form a hydrogen bond, and that is serine.  Both serine and threonine have hydroxyl groups located on the side chains of their amino acids.

The following options correctly express the relationship between the volume and temperature of a gas at constant pressure is C. The gas increase in volume because the particles increase in size

Charles' law is a law that studies the behavior of gases in chemistry, such as how temperature affects the volume of a gas under constant pressure. Charles's law describes empirical relationships in the form of special cases of the general gas law and can be derived from the kinetic theory of gases assuming an ideal gas.

According to Charles' law, if a gas is contained in a closed chamber with constant mass and constant pressure, then its volume is directly proportional to its absolute temperature. So when the volume of a gas is directly proportional to the constant temperature, when the temperature of the gas increases, the volume will also increase.

Disulfide bridges stabilize the tertiary level of protein structure.

Although many proteins are composed of many subunits, their organization into quaternary structures is not universal. Usually, disulfide bonds will link β-sheets, α-helices, and loops; this indicates that they predominantly maintain tertiary structure, as opposed to secondary structure, which refers to local conformations and is maintained mostly by hydrogen bonds, making proteins more stable and less likely to unfold. As the pH of a solution rises, acidic groups on proteins are deprotonated, resulting in a net positive charge on the protein. The spatial structure of a protein, however, is critical to its activity. It can only recognize and bind to the molecules it's designed to work with in its natural state.

True: Chemists knew that something other than mass influences the properties of elements.

The periodic table organizes elements according to periodic properties, which are recurring trends in physical and chemical properties. First, electrons are added one at a time across a period, from left to right. As this occurs, the electrons in the outermost shell experience increasing nuclear attraction, bringing them closer to the nucleus and more tightly bound to it. Second, moving down a column in the periodic table loosens the outermost electrons' bond to the nucleus. Thus, number of valence electrons, or valency, other than mass influences the properties of elements.

This occurs because the number of filled principal energy levels (which protect the outermost electrons from nucleus attraction) decreases within each group. The periodicity observed in the elemental properties of atomic radius, ionization energy, electron affinity, and electronegativity are explained by these trends.

No, a 1.5 M solution cannot be made from a 0.98 M solution.

Explain molarity

Probably the most frequently used unit of measurement for solution concentration is molarity, abbreviated as (M). The ratio of the number of liters of solution to the number of moles of solvent is known as molarity.

Knowing the molarity (M) of the solution of a specific volume will allow you to calculate the number of moles (n) of a chemical dissolved in a solution (V). The quantity of solvent moles per kilogram is known as molality, which is a property of solutions.

The final temperature of the liquid that is formed when 50 grams of ice and 500 g of water are mixed together is determined as follows:

Heat change = mc(T_f - Ti)

The heat of fusion = mL

where;

Heat lost water = mc(T_f - Ti)

c for water = 4.19 J/J/(g°C)

Heat lost water = 500 * 4.18 * (T_f - 20)

Heat lost water = 2090T_f - 41800

Heat gained by ice = mc(T_f - Ti) + mL + mc(T_f - Ti)

c for ice = 2.03 J/J/(g°C)

Heat gained by ice = 50 * 2.03 * {0 - (-20)} + 50 * 0.334 + 50 * 4.18 * (T_f - 0)
