Answer:
16.9g
Explanation:Cu+2AgNO3→2Ag+Cu(NO3)2
Cu will likely have a +2 oxidation state. It is higher in the activity series than Ag, so it is a stronger reducing agent and will reduce Ag in a displacement reaction. Then you need to balance the coefficients knowing than NO3 is -1 and Ag is +1.
Then to calculate the theoretical yield you need to compare moles of the reactants:
m(Cu)=5g
M(Cu)=63.55
n(Cu)=5/63.55=0.0787
By comparing coefficients you require twice as much silver: 0.157mol
n(Ag)=0.157
M(Ag)=107.86
m(Ag)=0.157x107.86=16.9g
Hence, the theoretical yield of this reaction would be 16.9g
Answer:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force,
Explanation:
The symbol for the hydroxide ion is OH-
The net force is the sum of all of the forces that cancelled out to zero. Hence, option D is correct.
<h3>What is force?</h3>
The pushes or pulls on an object with mass causes it to change its velocity.
The net force is the vector sum of all forces acting on an object. Force is a vector quantity.
Two forces of equal magnitude when acting on an object in opposite directions will cancel out each other.
As a result net force is equal to 0. The word net here shows the total force acting on the object.
Hence, option D is correct.
