A linear creep law is observed in an experiment on an alloy at high temperatures. Over time, the steady-state creep rate is observed to decrease. Briefly explain why. (b) Stainless steels are good high-temperature alloys because of the protection against oxidation provided by the passive oxide layer (Cr2O3). At high temperatures, Cr reacts with the Fe3C to form Cr23C6. What effect might this have on the corrosion resistance

h let me think

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

b
