Research the properties and use of road salt in winter conditions. Write a one page report

can u do it

Explanation:

just believe

A common way to clear icy roads is to apply a layer of salt, which lowers the freezing temperature of water and melts the ice. In fact, the American Highway Users Alliance found that road salt reduces collisions by up to 85%. However, road salt can cause vehicle parts to rust.

i hope this helps someee

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
