Is the following reaction spontaneous at 298 k? (answer by calculating delta g)
h2o(g)+c(s) -> co(g)+ h2(g)
delta h= 131.3 kj/mole
delta s = 134 j/mole k

The reaction H2O(g)+C(s) -> CO(g)+ H2(g) is NOT spontaneous because its ΔG =  91 kJ/moles

Explanation:

ΔG is calculated by ΔH - TΔS

ΔG = ΔH - TΔS

ΔG = 131.3 kJ/mole - 298K . 0,134kJ/mole K

ΔG = 91.068 kJ/moles

Be careful with the ΔS, because you have J, and in ΔH, you have kJ

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
