Balance the following oxidation-reduction reactions, which take place in acidic solution, by using the "half-reaction" method.
LuckyWell [14K]
First identify which is being oxidized and reduced. In this case, the Mg is being oxidized and the Hg is being reduced. 

Mg --> Mg+2 
 
<span>Hg+2 --> Hg+1 
</span>
Then you have to balance each half reaction first with electrons before adding them together in one equation

Mg ⇒ Mg^{+2}  +  2e^{-1}

and

2Hg^{+2} + 2e^{-1} ⇒ Hg_{2} ^{+2}
 
and then combine them together to form 

Mg + 2 Hg^{+2} + 2e ⇒ Mg^{+2} + 2e ^{-} + 2 Hg^{+1} + 2 e^{-}

It isn't necessary to keep the electrons but its essential to know how many there are in order to know how many are in the equation in order to calculate the reaction energy. Note: A<span>dd H+ and H2O to balance the H's and O's in acidic solution if needed.</span>

A sample of nitrogen gas is stored in a 489.6 mL flask at 108 kPa and 10.0°C. The gas is transferred to a 750.0 mL flask at 28.7
Wewaii [24]

Answer:

P2= 125.26 Kpa

Explanation:

V1= 489.6 ml=0.4896L

V2= 750 ml= 0.750L

V1= 180 KPa= 180000 Pa

P2= ?

T1= 10 = 10 + 273.15 = 283.15K

T2= 28.7+273.15= 301.85K

180000Pa* 0.4896L/ 283.15K * 301.85K/0.75L

P2= 12526.28553

P2= 125.26 KPa

Calculate the volume occupied by 16.3 moles of nitrogen gas at 273 K and 101.3kPa
erma4kov [3.2K]

Answer: V= 366.3 L

Explanation:

Using the ideal gas law; PV = nRT

P= pressure = 101 kPa  , n =  Number of moles = 16.3 moles

V = Volume = ?               R= Gas constant =  8.31 kPa L/Mol K

T= Temperature = 273K

We make ''V'' the subject of the formular;

V = n R T/ P =  16.3mol  x 8.31 kPa. L / mol. K x 273 K

                        -----------------------------------------------------

                                           101 kPa

                V  = 366.3 L
