Answer:

b. $2 NaI_{(aq)} + Hg_2(NO3)_{2(aq)} ---> Hg_2I_{2(s)} + 2 NaNO_{3(aq)}$

Explanation:

<em>Precipitation reaction is a form of chemical reaction in which an insoluble salt (a precipitate) is formed from an aqueous mixture of two soluble salts.</em>

This thus means that:

The two reactants in a precipitate reaction must be in aqueous forms
At least, one of the products must be a solid (precipitate)

From all the options, only option b fulfills the conditions for a precipitate reaction.

The correct answer is b.

How many moles of oxygen must be placed

Annette [7]

0.24 moles of oxygen must be placed in a 3.00 L container to exert a pressure of 2.00 atm at 25.0°C.

The variables given are Pressure, volume and temperature.

Explanation:

Given:

P = 2 atm

V = 3 litres

T = 25 degrees or 298.15 K by using the formula 25 + 273.17 = K

R = 0.082057 L atm/ mole K
