Below are the choices:A. Ni(CO)4(g) ⇌ Ni(s) + 4CO(g)B. C(s) +2H2(g) ⇌ CH4(g)C. CaCO3(s) ⇌ CaO(s) + CO2(g)D. N2(g) + O2(g) ⇌ 2 NO(g)The answer is A. Ni(CO)4(g) ⇌ Ni(s) + 4CO(g)The Kp/Kc ratio is equal to (RT)Δn. K is a constant and the temperature is held constant. So, the Kp/Kc ratio depends on Δn or the difference of moles of gaseous product and reactant. The reaction with the greatest Kp/Kc ratio is Ni(CO)4(g) ⇌ Ni(s) + 4CO(g) with a Δn of 3.

Reaction c. has the largest value of at 300 KExplanation:Here is the complete question Converting between Kc and Kp For which of the following reactions is the ratio Kp/Kc largest at 300 K?  a. N2(g) + O2(g) ⇌ 2 NO(g)b. C(s) +2H2(g) ⇌ CH4(g)c. Ni(CO)4(g) ⇌ Ni(s) + 4CO(g)d. CaCO3(s) ⇌ CaO(s) + CO2(g)Solutionwhere R = molar gas constant = 8.314 J/mol-K, T = temperature = 300 K and n = number of moles of products - number of moles of reactantsFor reaction a. number of moles of gaseous products = 2, number of moles of gaseous reactants = 2. So n = 2 - 2 = 0 So, For reaction b. number of moles of gaseous products = 1, number of moles of gaseous reactants = 2. So n = 1 - 2 = -1 (we do not include the solid) So, For reaction c. number of moles of gaseous products = 5, number of moles of gaseous reactants = 1. So n = 4 - 1 = 3 (we do not include the solid)So, For reaction d. number of moles of gaseous products = 2, number of moles of gaseous reactants = 0. So n = 2 - 0 = 2 (we do not include the solid)So, Since for reaction c which is the largest value. So, reaction c. has the largest value of at 300 K

d.) circle motion requires a force to give it a centripetal acceleration.

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.
