2 answers:

5 0

O2 travels slower than H2, Ne, N2, and CO. This is due to the fact that O2 has a heavier molecular weight than the others. O2 has a weight of 32 grams per mole. N2 and CO are the next highest with 28 grams per mole. Ne is 20 grams per mole, and H2 is 2 grams per mole.

Answer:

Explanation:

The distribution of the speed of gas particles is represented via a Maxwell-Boltzmann graph which is essentially a plot of the velocity of gas particles vs the fraction of gas particles.

A proper assessment of the velocity can be made by measuring the root mean square velocity of the particles which is given as:

$v_{rms} =\sqrt{\frac{3RT}{M} } ----(1)$

where, R = gas constant = 8.314 J/mol-K

T = temperature of gas in K

M = molecular weight of the gas

Based on equation (1), the velocity of the gas particle is inversely proportional to its molecular weight.

The molecular/atomic weights of the given gases are:

Ne = 20 g/mol

H2 = 2 g/mol

CO = 28 g/mol

N2 = 28 g/mol

O2 = 32 g/mol

Since O2 has the highest molecular weight, it will travel the slowest.

Propane can be turned into hydrogen by the two-step reforming process. In the first step, propane and water react to form carbon

Vsevolod [243]

Answer:

The net chemical equation is: 6 H2O(g) + C3H8(g) → 10 H2(g) + 3 CO2(g)

Explanation:

First equation:

The reactants propane and water react to form the products CO and H2

C3H8(g) + 3H2O(g) → 3CO(g) + 7H2(g)

Second equation:

The products CO and H2 will react

CO(g) + H2O(g) → H2(g) + CO2(g)

We should multiply the equation by 3 (to equal the products of the first equation)

3CO(g) + 3H2O(g) → 3H2(g) + 3CO2(g)

Add the second to the first equation:

C3H8(g) + 3 H2O(g) + 3 CO(g) + 3 H2O(g) → 3 H2(g) + 3CO2(g) + 3 CO(g) + 7 H2(g)

The net chemical equation is: 6 H2O(g) + C3H8(g) → 10 H2(g) + 3 CO2(g)

How are characteristic properties of a given substance different from its other properties and chemical properties?

lesya [120]

Answer : The characteristic properties of a substance always remains the same irrespective of the sample being observed is large or small.

Few examples of characteristic properties of any substances includes freezing or melting point, boiling or condensing point, density, viscosity and solubility. They are specific for specific substances and which makes them easily recognizable.

Whereas chemical properties are specific for one substance which chemically transformed into another substances.

Which of the following statements about the kinetic molecular theory are not correct?

Rashid [163]

Answer:

The false statement is: (C) The average kinetic energy of the molecules is not related to the absolute temperature

Explanation:

According to the Kinetic Theory of Gases, gases are composed of small fast moving particles that are in constant random motion. These gaseous particles are known as molecules.

It is assumed that the mass of all the gaseous molecules is the same and the intermolecular interactions (attractive or repulsive) are negligible.

Also, the total volume of all the gaseous molecules is considered to be negligible as compared to the volume of the container.

According to this theory, average kinetic energy (K) of the gaseous particles is directly proportional to the absolute temperature (T) of the gas, by the equation:

$K = \frac{3}{2}k_{b}T$
