the oxidation states of the elements before and after the reaction is;
Pb oxidation state changes from 0 to +2
SO₄²⁻ ion there's no change in the oxidation state during the reaction
Au oxidation state changes from +3 to 0
reduction reactions are when there's a decrease in the oxidation state of the species
oxidation reactions are when theres an increase in the oxidation state of the species
the element where there's a decrease in oxidation state is Au.
Therefore Au gets reduced.
answer is B) Au
Use the equation Q = mCT.
Q is the amount of energy in joules.
m is the mass in grams.
C is the specific heat of water (4.184 J/g °C).
T is the change in temperature.
0.700 pints = 331.224 g of water
Q = (331.224 g)(4.184 J/g °C)(100° C - 30° C)
Q = 97,008.885 J
Divide by 1,000 to convert to kilojoules:
97.009 kJ
Stannous flutoide is ionic
