What reaction is depicted by the given equation: au3 3e− au
mrs_skeptik [129]
This is a reduction half-reaction. Initially, gold exists as Au^{3+}, and after the reaction, it has been converted to elemental gold. To make this possible, three electrons must be added to <span>Au^{3+}. This fits within the definition of reduction reactions, where the reactant gains electrons in the reaction.</span>

A gas has a pressure of 0.470 atm at 60.0 C. What is the pressure at standard temperature?
OLEGan [10]

Answer:

P2=0.385atm

Explanation:

step one:

Given that the temperature T1=  60 Celcius

we can convert this to kelvin by adding 273k to 60 Celcius

we have T1= 333k

pressure P1= 0.470 atm

step two:

we know that the standard temperature is T2= 273K

Applying the temperature and pressure relationship we have

P1/T1=P2/T2

substituting our given data we have

0.47/333=P2/273

cross multiply we have

P2= (0.47*273)/333

P2= 128.31/333

P2=0.385 atm
