A welding torch requires 4122.8l of ethylene gas at 0.64 atm what will be the pressure of the gas if ethylene is supplied by a 51.6 l tank

Answers

Answer 1

The pressure of the gas if ethylene is supplied by a 51.6 l tank is 51.1355atm

The final pressure of the gas can be calculated by using the formula given by Boyle's law,

      P1V1 = P2V2

What is Boyle's law?

    Boyle's law relates the compression and expansion of gas at a constant temperature. It states that, At constant temperature the pressure exerted by a gas is inversely proportional to the volume of the given mass of gas.

      P1V1 = P2V2

where,

P1 is the initial pressure

V1 is the initial volume

P2 is the final pressure and

V2 is the final volume.

Given data:

Initial volume V1= 4122.8L

Initial pressure P1= 0.64atm

Final volume V2= 51.6L

Final pressure P2= ?

   0.64*4122.8= P2*51.6

   P2= 2638.592/51.6

   P2= 51.1355atm

Hence the final pressure of the gas is 51.1355atm

Explanation:

As octane is being burned it would be combustion reaction.

writing the balanced equation:

C8H18 + 25/2 O2 →  9 H2O + 8 CO2

now stepping up mole ratio from the balanced equation:

                   moles of octane    :      moles of carbon dioxide

                               1                  :                    8

                                3.5             :                    X

X = 3.5 x 8 = 28

therefore when 3.5 moles of octane are burned in air 28 moles of carbon dioxide are evolved.

now in order to calculate the mass of CO2 formed

molar mass of CO2 = 12 + (16 x 2) = 44g

now calculating the mass of 28 moles:

The formula for a substance is D4 and its molar mass is 30 g. A student is given 150 g of the substance and is asked how many atoms are in the sample. She says there are 5 times Avogadro's number (6.022 x 102) of atoms in her sample. The student is in error, identify her error and explain what the correct answer should be.

Answers

The student's error is that she is assuming that the number of atoms in a sample is directly proportional to the mass of the sample. Avogadro's number (6.022 x 10²³) represents the number of atoms or molecules in one mole of a substance. However, the number of atoms in a given mass of a substance depends on the molar mass (mass per mole) of the substance, not the Avogadro's number.

The correct way to determine the number of atoms in a sample is to use the formula:

number of atoms = mass of the sample / molar mass

In this case, the molar mass of the substance is 30 g/mol, so the number of atoms in 150 g of the substance is:

number of atoms = 150 g / 30 g/mol = 5 mol

The correct answer is 5 moles of atoms, which is not equal to 5 times Avogadro's number.

The temperature at which a substance transforms from a solid into a liquid is known as its melting point. The balance between the solid and liquid phases is reached at the melting point. Pressure affects a substance's melting point, which is often reported at a standard pressure of 1 atmosphere, or 100 kPa. The melting point is the fixed temperature at which a solid transforms into a liquid. For instance, at 0°C, ice cubes begin to melt and turn from a solid to a liquid.

How do you find melting point?

By placing a small amount of an organic solid in a tiny capillary tube, affixing it to the stem of a thermometer centred in a heating bath, and gradually heating the bath, one may calculate the temperature at which melting begins and finishes. Melting points are frequently used to describe and rate the purity of organic and inorganic crystalline substances. Pure compounds melt at a fairly narrow temperature range of 0.5 to 1 °C, whereas contaminated, impure chemicals frequently show a huge melting gap.

Draw the Lewis structure for CH5N. How many lone pairs does it have?

Answers

Lewis structure for CH₅N has one lone pair.

A lone pair, also known as an unshared pair or a non-bonding pair, is an unshared pair of valence electrons that are not shared with another atom in a covalent bond in chemistry. Atoms' outermost electron shell contains lone pairs. The Lewis structure can be used to locate them. Therefore, if two electron pairs are coupled but are not utilized in chemical bonding, they are referred to as lone pairs. As a result, the amount of valence electrons surrounding an atom is equal to the sum of the electrons in lone pairs and those in bonds.

In the valence shell electron pair repulsion theory (VSEPR theory), which describes the morphologies of molecules, the idea of a lone pair is employed. They are also mentioned in relation to Lewis acids and bases in chemistry. Chemists do not, however, always classify non-bonding electron pairs as lone pairs. Examples include transition metals, where non-bonding pairs are believed to be stereochemically inactive and do not affect molecular shape. The idea of a lone pair is less clear in molecular orbital theory (completely delocalized canonical orbitals or localized in some way), as the relationship between an orbital and the elements of a Lewis structure is sometimes not clear-cut. However, orbitals that are largely nonbonding or that are occupied are typically classified as lone pairs.

Rutherford's experiment paved the way for subsequent changes up to and including the currently accepted quantum mechanical atomic model as his  model of the atom, the structure of the nucleus became more well-defined following the discovery of protons (1919) and neutrons (1932) as the particle constituents of the nucleus.

Answer 3

The percent abundance is related to the number fraction as fi = Pi/100  and used as in the formula written above in order to find average mass

What is atomic structure?

Atomic structure refers to the structure of an atom comprising a nucleus (centre) in which the protons (positively charged) and neutrons (neutral) are present.

The average atomic mass in a.m.u of Element X given this information is ((121 * 43.2) + (123 * 53.1) + (129 * 3.70)) / 100

=5227.2 + 6531.3 + 477.3

=12235.8 / 100

122.358

Rutherford's experiment change the way scientists had previously viewed atomic structure as it provided insight into atomic structure, and Rutherford's model of the atom was proposed as a small, positive, massive nucleus contains the very vast majority of the mass of the entire atom with negatively charged electrons surrounding it at relatively large distances.

Rutherford's experiment paved the way for subsequent changes up to and including the currently accepted quantum mechanical atomic model as his  model of the atom, the structure of the nucleus became more well-defined following the discovery of protons in 1919 and neutrons in 1932 as the particle constituents of the nucleus.

It was during the 1920s that a "wave mechanical model" came along through the work of several physicists most importantly de Broglie, Heisenberg, and Schrodinger) and Bohr's concept of electrons "orbiting" the nucleus was abandoned in favor of "orbitals" which are more abstract probabilistic representations of electronic structure within an atom.
