A container contains CO2, CO, and N2O. If the P co2 = 450 mm Hg and Pco = 243 mm Hg and P N2O = 328 mm Hg. What is the total pressure of the container of
gases?

there all right good

explanation:

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

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
