Answer:
single displacement
Explanation:
the Fe was switched out with the C. they are the only ones that switched, making it a single displacement
Answer:
C. I, III , IV
Explanation:
As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
As the size of atom increases the ionization energy from top to bottom also decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.
I don’t know the answer either
Hi There!
Question - Write the net ionic equation for the reaction of sodium phosphate with iron (III) chloride. Include the complete ionic equation and label the spectator ions. Also be sure to label the reactants as products as solid, liquid, gas, or aqueous solutions
Answer: 
P.S. The + and - are in parentheses because they are below the number.
Hope This Helps :)
I think is the Third one tbh sorry if that’s not right
