AgC2H3O2 is: Silver acetate
All are the same. It equals to the same thing.
Answer:
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Explanation:
Answer:
There are three nitrogen atoms in the products. The law of conservation of mass states that the amount of substance should be the same before and after a reaction. ... balanced because the total number of oxygen atoms is 3.

You started with 0.72 mg of phosphorus and ended up with 10.01 mg of its bromide. So the amount of bromine is 10.01 - 0.72 = 9.29 mg
Now you need to determine the relative number of atoms of each element used.
atomic mass of phosphorus = 30.973762
atomic mass of bromine = 79.904
relative atoms of phosphorus = 0.72 / 30.973762 = 0.023245
relative atoms of bromine = 9.29 / 79.904 = 0.116265
Now you need to look for a simple ratio of integers that closely approximates 0.023245 / 0.116265. First we'll divide the larger by the smaller.
0.116265 / 0.023245 = 5.001597
Given how close the value comes to 5. The empirical formula will be PBr5. So for every atom of phosphorus, you need 5 atoms of bromine.</span>
