Answer:
simple chemistry experiment—adding baking soda to vinegar—seems to challenge the law of conservation of mass.
Answer:
The answer is Silver
Numbers of Protons in Silver: The element Silver (Symbol Ag) has the Atomic Number of 47. Any atom that contains exactly 47 protons in its nucleus is an atom of silver.

Answer:
C₂H₄O
Explanation:
Empirical formulas show the simplest ratio of atoms in a compound in whole numbers.
We can think that all the atoms are divisible by 4.
As we need the lowest number for each subscript, empirical formula is:
C₂H₄O
We have divided, 8/4 for carbon, 16/4 for H and 4/4 for O.
The empirical formula is also known as the simplest expression to represent a chemical
Answer:
121.8bar
Explanation:
The partial pressure is the pressure a gas would exert if it were alone in the volume of the gas mixture;
Given parameters:
Total pressure = 2558psi
Partial pressure of carbon dioxide = 54.6bar
Unknown:
Partial pressure of nitrogen dioxide gas = ?
Solution:
Total pressure = partial pressure of carbon dioxide + partial pressure of nitrogen dioxide gas
Let us convert from psi to bar;
14.504psi = 1 bar
2558psi = = 176.37bar
Now;
Partial pressure of nitrogen oxide = 176.37bar - 54.6bar = 121.8bar
