Catalytic Converter is the correct answer. Toxic gases are produced in the combustion reaction of an engine, and when this gas adheres to the converter, it’s chemically transmuted into something that’s harmless.

For 2Na (s) + Cl2(g) - 2NaCI (s) ,how many grams of sodium Chloride will be made from 115 g of sodium metal when reacted with ex

Solnce55 [7]

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
