Write the formula for a complex formed between ag and nh3, with a coordination number of 2.

Darya [45]3 years ago

Combination number 2 for silver means that it bonded to two species in the complex, in this way:

- Ag -

NH3 has coordination number one, which mean tha it only bonds to one speciesÑ

NH3 -

So, the complex is NH3 - Ag - NH3.

=> Molecular formula: Ag [NH3]2, now if you count the oxidation numbers you get:

 (2+) + 2*(-3) + 6(+1) = +2  - 6 + 6 = +2. So the complex has a net 2 positive charge, which gives the final fomula:

[Ag (NH3)2 ] (2+), where the final (2+) is a superscript that tells the charge of the complex.

in the two stage cooling method what is the maximum amount of time allowed for both stages cooling food from 135 to 41 degrees F
BlackZzzverrR [31]
In the past, restaurants had four hours, straight through, to cool food to 41°F or lower. Now the FDA recommends cooling food in two stages -- from 135°F to 70°F in two hours then from 70°F to 41°F or lower in an additional four hours for a total cooling time of six hours

Alekssandra [29.7K]

Answer:

A tritium is produced.

Explanation:

Combining two additional neutrons to the nucleus of the hydrogen atom makes it a tritium, Hydrogen-3.

   neutron is designated  ¹₀n; this shows a mass number of 1 and no atomic number

  Hydrogen-1 is designated as ₁¹H; a mass number of 1 and atomic number of 1. This particle is actually more like a proton.

        Combining both:

                  ₁¹H + 2¹₀n → ³₁H

This is a nuclear reaction and in balancing such reaction equation, mass numbers and atomic numbers must be conserved.
