I am not to sure because I have not studied this
Mostly the electrons will determine the reactivity
Answer:
Approximately
.
Explanation:
Look up the specific heat of gaseous neon:
.
Calculate the required temperature change:
.
Let
denote the mass of a sample of specific heat
. Energy required to raise the temperature of this sample by
:
.
For the neon gas in this question:
Calculate the energy associated with this temperature change:
.
Balance the equation first:
2 Fe+6 HNO3→2 Fe(NO3)3+3H2
Then calculate mass of Iron :
4.5×3.0×3.5 cm3(1 mL1 cm3)(7.87 g Fe1 ml)=371.86 g Fe
Now use Stoichiometry:
371.86 g Fe×(1 mol Fe55.85 g Fe)×(6 mol HNO32 mol Fe)=19.97 mol HNO3
Convert moles of nitric acid to grams
19.97 mol HNO3×(63.01 g HNO31 mol HNO3)=1258.3 g HNO3
