Answer:
Volume of gas is two-thirds the quotient of pressure and temperature
=
Explanation:
Ideal gas equation states that:
PV=nRT,
where P = pressure
R = Ideal gas constant
T = temperature
and V = Volume
This equation means that at equal conditions, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature, and directly proportional to the temperature at constant pressure.
Given: P/V = k; and VT = j (where j and k are constants)
tripled pressure ≡ V = P/3k and and doubled temp = 2j/T
Assuming constants j=k= unit (1)
V = P/3 = 2/T
<u>=2P/3T.</u>

Explanation:
The word equation for the formation of copper acetate is as follows;
copper + vinegar → copper II oxide → copper acetate
Copper and vinegar are reactants while the copper acetate is the product
Note that vinegar is a weak solution of acetic acid. Pure copper does not react with acetic acid (copper is less than hydrogen in the electrochemical series); however, a reactive oxide layer is formed upon exposure to air. This layer interacts with non-oxidizing acids to give green copper(II) compounds (DeMeo, 1997; Tétreault et al., 2003), a typical example of such compounds is the copper(II) acetate formed in the word equation above.
Acid rain forms new substances because it is capable of interacting chemically with surfaces. When substances are exposed to acid rain, they dissolve in water if they are soluble in acids to form new substances.
Answer:
Hard parts of the organism must dissolve
Explanation:
I just took the quiz/test and got it right
It's a saline solution, commonly used in many ways, primarly in chemistry and medicine (i.e. in intravenous therapy, nasal lavage or in biological and chemical experiments), but also for cleaning new piercings or rinsing contact lenses.
