how high must a column of water be to exert a pressure equal to that of a 760.0 mm column of mercury? (the density of water is 1.00 g/ml, whereas that of mercury is 13.6 g/ml). group of answer choices 29.92 inches 10.3 meters 760 mm 1.00 atm
To impose pressure equivalent to that of a 760.0 mm column of mercury, a column of water must be 10336mm tall, or 10.3m. Per unit area, pressure is the force exerted perpendicularly to an object's surface.
That force is dispersed across. The gauge pressure, also known as gauge pressure, is the pressure in relation to the surrounding air pressure. To express pressure, a variety of units are employed. Mercury is the smallest and sun-closest planet in the solar system. The quickest of all the planets that orbit the Sun, its orbit lasts 87.97 Earth days.

Lewis structure for acetamide, CH3CONH2. four (4) are the electron-pair geometry and molecular geometry around the two C atom. Sp3d2 is the hybridization of each of the C atoms.
When the valence bond theory failed to accurately predict molecular structure, hybridization was used to explain it. Organic compounds' bond angles have been experimentally found to be near to 109o, 120o, or 180o. The Valence Shell Electron Pair Repulsion (VSEPR) theory states that because electron couples resist one another, the bonds and lone pairs surrounding a core atom are often spaced apart at their greatest angles. The behavior of electrons inside of molecules is modeled using orbitals. Since the hydrogen atom is the only neutral atom for which the Schrödinger equation can be precisely solved, this approximation for simple hybridization is based on atomic orbitals that are similar to those found for that atom. The 2s and 2p atomic orbitals, which are akin to the excited state orbitals for hydrogen, are utilised in heavier elements including carbon, nitrogen, and oxygen. It is believed that hybrid orbitals are combinations of atomic orbitals that are overlaid on one another in different ratios.

The relationship between the quantities of reactants and products prior to, during, and after chemical processes is known as stoichiometry. Stoichiometry is based on the law of conservation of mass, which states that the sum of the masses of the reactants and products must equal one another. This realization led scientists to conclude that the ratio of positive integers is typically formed by the relationships between the quantities of the reactants and products. This means that the amount of the product may be determined if the amounts of the individual reactants are known. On the other hand, if the amount of one reactant is known and the amount of the products can be computed using empirical data, the amount of the other reactants can likewise be calculated. This is seen in the following figure, where the balanced equation reads: CO2 + 2 H2O CH4 + 2 O2
In this reaction, two molecules of oxygen gas combine with one methane molecule to form carbon dioxide and two molecules of water. A full combustion is demonstrated in this chemical equation.

how would a calculated molar mass be affected if you take into account the volume of gas particles
When measured at the same temperature and pressure, the molar volumes of all gases are the same. Different gases will have different molar masses, though. This implies that the densities of various gases will vary (different masses per unit volume).
The volume occupied by one mole of a chemical element or chemical compound at standard temperature and pressure (STP) is known as the molar volume (Vm).

What is a crystal structure?
In crystallography, a crystal structure is a description of the regular arrangement of atoms, ions, or molecules within a crystalline material. The ordered structure results from the inherent property of constituent particles to form symmetrical patterns that repeat along the main directions of the three-dimensional space of matter.
The smallest group of particles in the material that make up this repeating pattern is the unit cell of the structure. A unit cell perfectly reflects the symmetry and structure of the entire crystal. It is constructed by repeatedly moving the unit cell along the principal axis. The translation vector defines the nodes of the Bravais lattice.
The length of the long axis or edge of the unit cell and the angle between them is the lattice constant, also called the lattice parameter or cell parameter. Crystal symmetry is described by the space group concept. All possible symmetric arrangements of particles in three-dimensional space can be described by the 230 space group.

Partial pressure of argon is 0.763 atm.
In Dalton's law, total pressure is the sum of individual pressures.
P total = P1 +P2
P total = P Ar + P ethane
P ethane = 1 - 0.763
= 0.237 atm
Partial pressure of ethane is 0.237 atm.
