Chemistry

Answer:

[Cr(NH3)6.]C13

Explanation:

Alfred Werner's coordination theory (1893) recognized two kinds of valency;

Primary valency which are nondirectional and secondary valency which are directional.

Hence, the number of counter ions precipitated from a complex depends on the primary valency of the central metal ion in the complex.

We must note that it is only these counter ions that occur outside the coordination sphere that can be precipitated by AgNO3.

If we consider the options carefully, only [Cr(NH3)6.]C13 possess counter ions outside the coordination sphere which can be precipitated when treated with aqueous AgNO3.

List the protons, neutrons, and electrons for Ge2+<br> Please hurry
Nady [450]

Answer:

32, 30 and 41

Explanation:

The problem here is to find the number of:

    Protons, neutrons and electrons in Ge²⁺

In this ion,

   We must understand that for a net positive charge to remain on an atom, the number of protons must be greater than the number of electrons.

Ge is Germanium with atomic number of 32;

So the number of protons is 32

Since the atom has lost two electrons;

  Number of electrons now is 32  - 2 = 30

Number of neutrons is 41 from the periodic table.

Blank Na2CO3 + blank Ag3P --&gt; blank Na3P + blank Ag2CO3
mezya [45]

Answer: __3__Na2CO3 + __2__Ag3P → __2__Na3P + __3__Ag2CO3

Explanation:

In balancing equations you need to make sure the number of atoms before the reaction should be equal to the number of atoms after the reaction.

Before the reaction: We had 6Na, 9CO, 6Ag and 2p

After the reaction: We have 6Na, 9CO, 6Ag and 2p

And now we are sure that atoms before the reaction are equal to atoms after the reaction
