AgNO3 reacts with CoCl2 based on the following equation:
<span>AgNO3 + CoCl2 ........> CoNO3 + AgCl<span>2
</span></span>
The complete ionic equation for this reaction is:
<span>Co2+(aq) + 2Cl- (aq) + 2Ag+(aq) + 2NO3-(aq) ...> 2AgCl(s) + Co2+(aq) + 2NO3-(aq) 
</span>while the net ionic equation is:
<span>Cl-(aq) + Ag+(aq) → AgCl(s)
</span>
From this ionic equations, we can see that Co2+ and NO3- remained unchanged in the ionic equations. Therefore <span>Co2+ and NO3- are the spectator ions.</span>

Determine the volume, in liters, of 3.2 mol of CO2 gas at STP.
Allushta [10]

Answer:

71.7 L

Explanation:

Using the ideal gas equation;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/Kmol)

T = temperature (K)

According to the information provided in this question;

P = 1 atm (STP)

V = ?

n = 3.2mol

T = 273K (STP)

Using PV = nRT

V = nRT/P

V = 3.2 × 0.0821 × 273/1

V = 71.7 L
