Hi there! I had the same question on my test as well!
The correct answer is (A) Homogeneous mixture!
I hope I helped you, and I am 100% this is the right answer!
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.

The larger and heavier the box, the more force you must use when pushing.
Answer: 120.9 grams
Explanation:
Given the question : How many grams are in 3.67 moles of Lithium cyanide?
Chemical formula of lithium cyanide = LiCN
Molar mass of LiCN: Li = 6.941 ; C = 12, N = 14
LiCN = (6.941 + 12 + 14). = 32.941 g/mol
(Gram of substance / mole of substance) = (molar mass of substance / one mole)
(Gram of substance / 3.67) = (32.941 / 1)
= gram * 1 = 3.67 * 32.941
Gram of substance = 120.89347
= 120.9 grams
