Density * Volume = Mass
Now we substitute the values in.
19.3 g/cm^3 + 20 cm^3 = 386 g
Mass = 386 g
Acid rain is rain with very low pH! Hope this helps!
False it can only be one to take place
Answer: The nonliving parts of an ecosystem are called abiotic factors. Abiotic factors include water, sunlight, oxygen, temperature, and soil.
Explanation:
Law of conservation of matter/mass
the law of conservation of mass states that matter cannot be created nor destroyed but can be changed from one form to another.
by Antoine Lavoisier
Law of multiple proportions
the law of multiple proportions states that if two elements, A and B combine to form more than one chemical compound, the various masses of element A, which combine separately with a fixed mass of the other element B are in simple multiple ratios.
by chemist John Dalton
Law of reciprocal proportion
the law of reciprocal proportion states that the masses of several elements A, B, C
which combine separately with a fixed mass of another element D are the same as or simple multiples of, the masses in which A, B, and C themselves combine.
by Jeremias Richter
Law of definite proportions
the law of definite proportions states that all pure samples of a particular chemical combined contain similar elements combined in the same proportion by mass.
by Joseph Proust
