Answer:
14.5 g silver
Explanation:
This is a problem using the stoichiometry of the reaction. First thing we need is the balanced equation:
Zn + 2 AgNO3 ----------------------- 2 Ag + Zn(NO3)2
We know that 14.6 g of Zn did not reacted, then we can calculate the amount of Zn reacted and do the calculation given the above reaction.
amount Zn reacted: 19.0 -14.6 g Zn = 4.4 g Zn
atomic weight of Zn: 65.37 g/mol
mol Zn reacted: 4.4 g Zn x ( 1 mol Zn/ 65.37 g Zn) = 0.067 mol Zn
We know from the balanced equation that moles of Ag are produced from 1 mol Zn therefore the mol of Ag produced are:
0.067 mol Zn x 2 mol Ag/ 1mol Zn = 0.135 mol Ag
and the mass of silver then will be given by multiplying by the atomic weight of silver:
0.135 mol Ag x 107.9 g/mol = 14.5 g Ag
ANSWER:
Most of them are silver, they all have a face on them.

Answer:
NH3OH⁺ is the strongest acid
Explanation:
NH2OH + CH3NH3⁺ 
CH3NH2 + NH3OH⁺
Equilibrium favours backward, so NH3OH⁺ is giving H⁺ so NH3OH⁺
The system lies to the left so the reaction is going in backward direction.
So CH3NH2 reacts with NH3OH⁺ to give NH2OH it implies that the H+ is transferred from NH3OH⁺ to CH3NH2, so here the strongest acid is NH3OH⁺. strongest base will be: CH3NH2.
Thus, Equilibrium favours backward, so NH3OH⁺ is giving H⁺ so NH3OH⁺ is the strongest acid
