You have obtained a job at a small microbrewery, and have been tasked with growing a new strain of yeast under purely aerobic conditions without any major products. the biologists working with you have told you that the biomass has a chemical formula of ch1.7900 54no.18 with 6% ash, the best substrate for optimal biomass production is sucrose, and ammonia should be used as the nitrogen source. the biomass yield from sucrose is 0.8 g/g. a) write down and balance the stoichiometric equation. use an electron balance to you solve this problem (assume nitrogen valency is relative to nh3). show your work and/or indicate what resources you used to solve this problem. b) what are the heating/cooling requirements for this process per g of biomass produced? (hint: read the problem statement indicate whether heat must be added or removed for full credit. c) did you need to solve the entire stoichiometric equation to solve part b? if not, what were the key values? write down the equations would you use to calculate these values efficiently.

When you are in a cool place and exhale into your mask, the mask blocks and re-directs some of your breath up toward the top edge of the mask and under your glasses. ... When the warm breath hits the cool lens, the water in the breath condenses causing your lenses to fog up.
