Answer:
In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.

Answer:
The mass of silver carbonate precipitated is 5.18 grams.
Explanation:
Molarity of the silver nitrate solution = 0.671 M
Volume of the silver nitrate solution = 56.0 mL
Moles of silver nitrate = n
Moles of silver nitrate used = 0.0376 mol
According to the reaction, 2 moles of silver nitrate gives 1 mole of silver carbonate, then 0.0376 moles of silver nitrate:
Moles of the silver carbonate formed = 0.0188 mol
Molar mass of silver carbonate = 275.7453 g/mol
Mass of silver carbonate :
The mass of silver carbonate precipitated is 5.18 grams.
We are given with the initial concentrations of both reactants, nitrous oxide and chlorine of 0.16 M and the value of the rate constant equal to M. The initial rate constant is required in this problem. The rate is expressed in k NO^2 *Cl2. Substituting 0.16 to both components, the initial rate is 0.12288.
D = m/v. v = (3)^3 = 27.
D = 27/27. D = 1g/cm^3
