A sample of gas contains 0.1800 mol of CO(g) and 0.1800 mol of NO(g) and occupies a volume of 23.2 L. The following reaction tak
baherus [9]

Answer:

The volume of the sample is 17.4L

Explanation:

The reaction that occurs requires the same amount of CO and NO. As the moles added of both reactants are the same you don't have any limiting reactant. The only thing we need is the reaction where 4 moles of gases (2mol CO + 2mol NO) produce 3 moles of gases (2mol CO2 + 1mol N2). The moles produced are:

0.1800mol + 0.1800mol reactants =

0.3600mol reactant * (3mol products / 4mol reactants) = 0.2700 moles products.

Using Avogadro's law (States the moles of a gas are directly proportional to its pressure under constant temperature and pressure) we can find the volume of the products:

V1n2 = V2n1

<em>Where V is volume and n moles of 1, initial state and 2, final state of the gas</em>

Replacing:

V1 = 23.2L

n2 = 0.2700 moles

V2 = ??

n1 = 0.3600 moles

23.2L*0.2700mol = V2*0.3600moles

17.4L = V2

<h3>The volume of the sample is 17.4L</h3>

A persistent or nonvolatile chemical agent can: Select one: a. explode without warning and releases gases. b. remain in the envi
avanturin [10]

Answer: A persistent or non-volatile chemical agent can remain on a surface for more than 24 hours.

Explanation:

Non-volatile substance is defined as the one which does not readily evaporate into its surrounding. Generally, a non-volatile substance has strong intermolecular forces between its molecules.

A non-volatile substance will take more than 24 hours to remain on the surface.

On the other hand, a substance with weak intermolecular forces present in its molecules will readily evaporate into the atmosphere.

For example, acetic acid is a volatile substance and quickly evaporates into the atmosphere.

Thus, we can conclude that a persistent or non-volatile chemical agent can remain on a surface for more than 24 hours.
