Yes I think & I Belive it moves across the surface
Percent yield = (Actual Yield/ Theoretical Yield) x 100
Given, Actual Yield of silver = 410 grams
Given, mass of copper = 127 g
Atomic mass of copper = 63.546 amu
Formula: Moles = mass / atomic mass
Moles of copper = 127 g/ 63.546 amu = 1.998 mol
Based on the given balanced chemical reaction, the molar ratio between Cu: Ag is 1:2
So 1.998 mol of copper should yield (2 mol Ag/ 1 mol Cu) x 1.998 mol of Cu = 3.996 mol
Calculated mol of Ag = 3.996 mol
Atomic mass of silver = 107.8682 amu
Mass of silver = moles x atomic mass = 3.996 mol x 107.8682 amu = 431 g
Based on the math, the theoretical yield = 431 g
Percent yield of silver = (410g/431g) x 100 = 95. 13%
The answer is 95. 13%
The correct options are as follows:
1. In the chemical equation given above, Fe3+ IS REDUCED.
A reduction is a process in which an atom of an element gains an electron and therefore become reduced. In this type of reaction, the positive character of the atom is reduced. Looking at the equation given above, you will notice that, the positive character of Iron is reduced form +3 to +2.
2. In the reaction given above, the chlorine atom is OXIDIZED.
An oxidation is a process in which an atom loses an electron, thereby increasing its oxidation number. In this case, the positive character of the atom is increased. Looking at the chlorine atom given above, you will notice that it has a charge of -1 before and now it has change to neutral, which means that, it has given out the electron it gains earlier.
3. This type of redox reaction can not take place. This is because, in chemical reaction, the chlorine atom is always looking for another element that will donate an electron to it in order to become stable. Thus, chlorine atom easily gain electrons but it can not donate an electron to another element.<span />
