Answer:
C
Explanation:
Because nothing is left at the end of the reaction.
Answer:
H2SO4
Explanation:
H2SO4 is actually one of the strongest acids, coming to pH value very close to 1 . Acids transfer their hydrogen ions to other substances , such as water , and usually have hydrogen their formula . In this case , H2SO4 has hydrogen in its formula and is acid in the case .

because it’s outside of the country!
good luck :)
The number of Al atoms is greater than the number of Sn atoms
<h3>
Further explanation</h3>
Given
20 gram sample of Tin and Aluminum
Required
Number of atoms
Solution
<em>1 mol = 6.02 x 10²³</em> particles (atoms, molecules, ions)
So the number of atoms of each element is determined by the number of moles. The greater the number of moles the greater the number of atoms
- moles Sn-Tin(Ar = 118,71 u)
mol = mass : Ar
mol = 20 : 118,71 u
mol = 0.168
- moles of Al-Aluminum(Ar=26.9815 u)
mol = 20 : 26.9815 u
mol = 0.741
So the number of Al atoms > number of Sn atoms
