The answer is: B) Spills in your shop and any releases on pavement or outside should be poured down a drain.
Pouring used oil down a drain can cause damege to environment.
Oil is nonpolar substance and does not dissolve in the water (polar molecule), used oil remain existent in the drain and sewer or in the environment.
Small spills create a cumulative effect with significant impact on the environment.
Untended spills inside a shop can spread to an inside drain connected to the storm sewer system and cause floods.
Chemically combined
Answer:
A compound
Explanation:
A compound is a substance made up of two or more components that are chemically combined together.
The substances that combines to form a compound is called elements.
The properties of compounds are distinct and different from the elements that combines to make them.
A wide array of compounds are known and they arise from different arrangements of atoms of elements.
B Solid
C Mixture
D Pure Substance.
From the way the cheese melted, Steve knows that Cheese is a mixture.
Thus, option C is correct.
Mixtures are composed of two or more different substances that have not been chemically combined.
The following is a list of mixture’s properties:
A physical combination of two or more pure chemicals that maintains each substance's unique chemical identity is referred to as a mixture.
A single type of matter, known as a pure substance, cannot be physically separated into other types of matter.
Mixtures are not pure substances, but elements and compounds are. The elements that make up a compound are substantially distinct from one another.
Hence, cheese is a mixture since it’s components can be easily separated and are not chemically combined.

#SPJ2
Answer:
pH Scale:
The pH scale refers to the negative logarithm of molar concentration of hydrogen ions: pH = -log [H+].
Characteristics:
The pH scale ranges from 0 to 14. A solution of a compound of pH 7 or pOH 7 is a neutral solution. Solutions of pH less than 7 are acidic and more than 7 are basic.
Low pH of water is acidic in nature as it enters into the ground and collects in streams, it can have bad impacts on the ecosystem.

column 1 Atoms
column 2. lons
column 1 Crystalline
column 2 Noncrystalline
column 1. Definite shape
column 2. Definite volume
column 1 Viscous
column 2 Nonviscous
Answer:
column 1: they are solids that form crystals.
column 2: Are liquid solutions.
Explanation:
Crystals are solids, some of them can have viscosity like glass.
Liquid solutions, are formed by some ions dissolved in water, so they can have a definite volume and could be a liquid that is nonviscous because they are dissolved in water.
