How is the cost of a bolt 5 cents? If one nut costs $1.00 and the total cost is $1.10, that leaves 10 cents remaining. If one bolt costs 5 cents then you’d have two bolts and one nut, unless the cost of the bolt is supposed to be 10 cents. Less

Oh never mind, I answered my own question.

let Y=nut, X=bolt Y=X+$1-----------------eq(1) Given X+Y=$1.1 X+X+$1=$1.1-----from eq(1), Y=X+$1 Bolt X=0.05=5cents nut Y= $1.05 Less

Thought of a specific moment when I had fixed a problem that immediately hindered the companies operations. They want details so it can be difficult to recall a specific moment or to choose one out of many possible times. The idea is to already have something interesting before hand. Less


Please write down the equations for pH and Arrhenius Law.

1 Answers

I wrote down the equation for pH. I got the Arrhenius Law about 85% correct - and noted that I couldn't fully recall the exact calculation because my background is in production chemicals. If that is necessary, I would google the formula needed. Less

Yes to all .


They are looking for more environmentally friendly way to approach the need for organic solvents and the carcinogenic vapors. They were looking for someone to manage the building of the on-site lab for product manufacturing and designing the SOPs for manufacture.

The product is awesome and inspiring. Solvents can be managed following EPA and OSHA requirements, particularly with activated charcoal in the vent hoods as recovery would be expensive and unnecessary. The lab is going to need floor drains for the eye wash station and shower, which can be installed with a raised floor on the existing slab. I recommend ergonomic mechanical apparatus for chemical processing as too much human interface leaves employees vulnerable to accidental exposure. Double gloves, and kitchen warming trays are a bad idea. Organic solvents will dissolve gloves and kitchen warming trays increase vaporization rate and product loss. Proper PPE is strongly recommended along with closed systems for processing. Less
