An aerosol mixture of particulates and sulfur compounds form a grayish-colored substance that is called <u>industrial smog</u>.
<h3>What is Particulate Matter?</h3>
Airborne particulate matter (PM) is a composite of several chemical species rather than a single contaminant. It consists of a complex mixture of solids and aerosols, including dry solid particles, liquid-coated solid cores, and minute liquid droplets. Particles can contain inorganic ions, metallic compounds, elemental carbon, organic compounds, and chemicals from the earth's crust. They can vary greatly in size, shape, and chemical makeup. For the goal of regulating air quality, the particle diameter is used.
Those that have a diameter of 10 microns or below (PM10) are inhalable and can have a negative impact on health. Particles with a diameter of 2.5 microns or less are considered to be fine particulate matter (PM2.5). Consequently, a percentage of PM10 is made up of PM2.5.

Answer:
The temperature is 42.5 °C
Explanation:
We apply the Law of Ideal Gases to solve this:
P . V = n . R . T
First, we convert the bar into atm, so we make a rule of three.
1.013 bar is 1 atm
1.3 bar is (1.3 . 1) /1.013 = 1.28 atm
1.28atm . 15L = n . 0.082 . T
We must convert the mass to moles ( mass / molar mass)
20 g / 30 g / mol = 0.666 moles
1.28atm . 15L = 0.666 mol . 0.082 . T
(1.28 atm . 15L) / (0.666 mol . 0.082) = T
315.5 K = T
As this is absolute temperature we must convert to °C
315.5 K - 273= 42.5 °C
Answer:
dispersion, dipole-dipole, and hydrogen bonding
Explanation:
The pictured compound is an amine. Amines have high boiling points. Amines have such high boiling points because they posses about three different kinds of intermolecular interactions, viz; hydrogen bonds, dispersion forces and dipole-dipole interactions.
The dipole interactions and hydrogen bonds arise from the fact that the N-H bond is polar. Also recall that a hydrogen bond is formed when hydrogen is bonded to an electronegative element. Hydrogen bonds lead to significant intermolecular association and high boiling points.
Hence the three kinds of intermolecular forces present in the pictured compound are; hydrogen bonding, dipole interactions and dispersion forces.
The reserve of a fossil fuel might be increased if mining or extraction techniques improve so that more of fuel can be extracted for a profit
Answer:
d. there are no conditions for this correlation.
Explanation: Dispersal of matter is a term used to describe the various processes and activities involved in the transfer of materials from one location to another.
The spontaneity of a process tries to explain that a process will continue to occur when an initial force has been applied, it doesn't require the continous input of energy for it to continue to take place.
