What reagent would distinguish between Ag+ and Fe3+?

1 answer:

8 0

The reagent which is used is "NaI", that is Sodium iodide.
When the reagent sodium iodide is added to distinguish the Ag⁺ ions and Fe³⁺ ions, it will react and form precipitate with one, while have no precipitates formed with the other, so that is how we can distinguish both of them.

Balance the following chemical equation: __N2H4+ __O2 = __NO2 + __H2O

Deffense [45]

The answer for the following question is mentioned below.

$N_{2}H_{4}$ +3 $O_{2}$ →2 $NO_{2}$ +2 $H_{2} O$

the equation is balanced.

Explanation:

The steps required to balance a chemical equation is:

Firstly,write the formula of the compound/substance.

Secondly,count the number of atoms in each element on each side of the equation

Thirdly,Adjust the co-efficient.Balance the atoms or the ions present in the greatest number.

You may do this by finding the lowest common multiple of two.

Continue systematically to balance the atoms or ions on the rest of the side (i.e.)on the other side.

Lastly,check the number of atoms each elements is same on both the sides

From the equation:

Before balancing the equation:

$N_{2} H_{4}$ + $O_{2}$ → $NO_{2}$ + $H_{2} O$

After balancing the equation:

$N_{2}H_{4}$ +3 $O_{2}$ →2 $NO_{2}$ +2 $H_{2} O$

Therefore the given equation is balanced.

What is The atomic sublevel with the next highest energy after 4p is

cluponka [151]

Answer:

Explanation:

The atomic sublevel with the next highest energy after the 4p is 5s.

Based on Aufbau's principle; the sublevels with lower energies are filled up before those with higher energies.

Sublevels do not fill up based on numerical order. The pattern of filling is shown as:

1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p
