1. A factory employee drops a 100 L concentrated sulfate acid canister, which is full of pH, into a neutral pool containing 900 L of water, and all the sulphate acid in the canister mixes into the pool.

a) How many kg of pure NaOH should be added to neutralize the water in the pool.

b) To remove sulfate ions formed as a result of ionization of sulfate acid as BaSO4 and remove it from water b) How many kg of pure BaCl2 salt should be added to water?

NOTE: Concentrated sulfate acid is 98% by mass.

In R-Syntax, create a vector of 100 employees ("Employee 1", "Employee 2", ... "Employee 100") [Hint: use the `paste()` function and vector recycling to add a number to the word "Employee"] then create a vector of 100 random salaries for the year 2017 [Use the `runif()` function to pick random numbers between 40000 and 50000] and finally create a vector of 100 salary adjustments between -5000 and 10000 [use runif() to pick 100 random #'s in that range]
