5.25 grams of baking soda (NaHCO3) and excess vinegar were combined (reaction below).NaHCO3 (s) + CH3COOH (aq) NaCH3COO (aq) + H2O (l) + CO2(g)
a.How many moles of CO2gas areproduced? Hint: use mole ratio.
b.Whatvolume of CO2gas is produced when the reaction takes place at1.12 atm, 22.85 °C?
c.Instead of doing this reaction in an air-conditioned classroom, the same reaction is performed outside on a hot Indiana summer day at 32.22 °C. Will the volume of CO2gas produced increase, decrease, or stay the same?Explain your choice.
4. At 10°C and 1 atm, x L of O2 gas is required to react with 0.85 g of glucose, what is the value of x? The unbalanced reaction is shown below:
C6H12O6 (s) + O2(g) → CO2(g) + H2O(l)
Consider these reactions:
Reaction 1: H 2 (g)+Cl 2 (g) longrightarrow 2HCl(g) Delta*H = - 184.6kJ
Reaction 2: 2OF 2 (g) longrightarrow O_{2}(g) + 2F_{2}(g) Delta*H = - 49.4kJ
Reaction 3: N 2 (g)+2O 2 (g) longrightarrow 2N*O_{2}(g) Delta*H = 66.4kJ
Use Reaction 3.
