Answer:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Explanation:
We are to give the reaction expression for this displacement reaction.
Reactants = copper and silver nitrate solution
Products = silver and copper (II) nitrate
Copper = Cu
Silver nitrate solution = AgNO₃
Silver = Ag
copper (II) nitrate = Cu(NO₃) ₂
So:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Answer:
Susan is right
Explanation:
Honey is a natural substance extracted from bees. Like every other natural substance, honey is a mixture of many different substances. An analysis of the so called 'pure honey' will reveal that many chemical species compose the natural substance called honey.
Hence Susan is right when she says that honey is not really pure but a mixture of substances.
IAL is the suffix pertaining to conditions percent are birth.
Answer :
Formal charge on C: (-1)
Formal charge on N: (0)
Net charge: (-1)
Explanation :
First we have to determine the Lewis-dot structure of .
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The given molecule is,
As we know that carbon has '4' valence electrons and nitrogen has '5' valence electrons.
Therefore, the total number of valence electrons in = 4 + 5 + 1= 10
According to Lewis-dot structure, there are 6 number of bonding electrons and 4 number of non-bonding electrons.
Now we have to determine the formal charge for each atom.
Formula for formal charge :
Net charge = -1 + 0 = -1
Answer:
Dilute the mixture with distilled water
Explanation:
3% solution: mix 1 part of 35% food grade hydrogen peroxide with 11 parts distilled water. Ratio is 1 to 11.
