Look at the following reaction.

Suppose that you are given the following information for this reaction at room temperature:
for SO₂(g) = -300.19 kJ/mol
for O₂ = 0.0 kJ/mol
for SO₃ = -371.1 kJmol
Find the value for ΔG° for this reaction and state whether the forward reaction is spontaneous, non-spontaneous, or at equilibrium.
a. ΔG° = 141.8 kJ / mol. The forward reaction is spontaneous.
b. ΔG° = 70.91 kJ / mol. The forward reaction is non-spontaneous.
c. ΔG° = 141.8 kJ / mol. The forward reaction is non-spontaneous.
d. ΔG° = 141.8 kJ / mol. The reaction is at equilibrium.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

he would use the colour black

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
