<u>Answer:</u> The amount of silver produced in the given reaction is 459.63 g.
<u>Explanation:</u>
According to mole concept:
1 mole of an atom contains 
number of atoms.
For the given chemical equation:
By Stoichiometry of the reaction:
1 mole of copper produces 2 moles of silver.
This means that, number of atoms of copper produces 
number of atoms of silver.
So, 
number of atoms of copper will produce = 
number of atoms of silver.
We know that:
Mass of 1 mole of silver = 107.87 g
Using mole concept:
If, number of atoms occupies 107.87 grams of silver atom.
So, 
number of atoms will occupy = 
Hence, the amount of silver produced in the given reaction is 459.63 g.
The compound HNO3 is called nitric acid.
HNO3 is a covalent compound and a strong acid which ionizes in water into H+ (proton) and NO3- (nitrate ion).
HNO3 (aq) ↔ H+(aq) + NO3-(aq)
Ans: HNO3 = Nitric Acid
[On a side note: Nitrous acid is HNO2]
Answer:
0.125
Explanation:
no of moles = given mass / molar mass
no of moles = 7/
molar mass of calcium oxide = atomic mass of calcium + oxygen
molar mass = 40 + 16
molar mass = 56
no of moles = 7/ 56 = 1/8 = 0.125
Atomic number and the number of protons are the same...
Neutrons = Mass number - number of protons
Electrons are same # unless there is a charge
The whole number you see on the periodic table is the atomic number of the element which is also same as the number of protons
1) carbon - 14 ; Mass number = 14 , Protons = 6 , Neutrons = 14 - 6 = 8
Electrons = 6
2) Lead - 208 ; Mass # = 208 , Protons = 82 , Neutrons = 208 - 82 = 126
Electrons = 82
3) Uranium - 239 ; Mass # = 239 , Protons = 92,Neutrons = 239 - 92 = 147
Electrons = 92
4) Uranium - 238 ; Mass # = 238 , Protons = 92 , Neutrons = 238 - 92 = 146
Electrons = 92
5) Tin - 118 ; Mass # = 118 , Protons = 50 , Neutrons = 118 - 50 = 68
Electrons = 50
Then something would go down.
