June Pride STEM Stories- Brian

(From June 2nd, 2017)  "I'm getting my PhD in biology (studying neural development using the retina as a model system). As a gay man, I've been incredibly fortunate to benefit from the long struggle the previous generations of LGBT+ community has fought to change public opinion as well as to have lived in more progressive … Continue reading June Pride STEM Stories- Brian

June Pride STEM Stories- Joe

(From June 2nd, 2017) "I'm in the process of getting Bachelors in Physics and Mathematics. Being a gay person was one of the reasons I ended up studying and loving science. Growing up in a rural, conservative community I felt it was in my best interests to remain deeply closeted, and instead of dwelling on … Continue reading June Pride STEM Stories- Joe

June Pride STEM Stories- Stella

(From June 2nd, 2017) "I'm a mathematician who does CS research for a government consulting firm. I'm also bisexual and transgender. I've been shocked at how accepting my university professors (U. Chicago) were, and how accepting my company was (seriously, how many billion dollar cooperators are places where an autistic trans person would feel comfortable?)... … Continue reading June Pride STEM Stories- Stella

June Pride STEM Stories – Ari

(From June 2nd, 2017) "So here is my story. I have been in science for quite a while and have had a varying degrees of support as well as non support. I started out over a decade ago going from major to major until one professor ended up really engaging me and getting me excited … Continue reading June Pride STEM Stories – Ari

June Pride Month Stories

Hello everyone! Here at Heychem we're doing our best to be socially active in the STEM community. Last post, I chatted about my ideas for profiles on prominent LGBTQIA+ chemists as a sort of celebration. After that, I got an idea to reach out through social media to learn from everyday researchers, engineers, and scientists … Continue reading June Pride Month Stories

Determining the Molar Solubility of Iron (II) Hydroxide

Given Question: Calculate the molar solubility of Fe(OH)2 (Ksp=4.87*10^-7).  Tutor's Note: The Ksp radical that's written down comes in later, I got confuzzled by my own notes! Happens to all of us. Sorry students 🙂  Step 1: Write out the reaction equation with all ions. Make sure it's balanced! We'll use this in the next step with … Continue reading Determining the Molar Solubility of Iron (II) Hydroxide

Episode 4: Reactions

Episode 4: All about reactions! I wanted to address how to work with and use reactions/reaction equations. It is extremely useful to be well-versed in writing and balancing equations when studying chemistry. Troubles viewing this video? Check us out on Youtube. Music: Vulgaret- Continent Drift Comments?

Determining Precipitate Yield (g) in Aqueous Solution

Given Question: Given the reaction: K3(PO4)+ Ni(SO4)→ K3(SO4)(aq)+Ni(PO4)(s), with 100.0 ml of K3PO4 and 200.0 ml of NiSO4 under standard conditions, how many grams of precipitate form?  Step 1: Determine the limiting reactant and the precipitate.  In order to determine the limiting reactant, one must convert all reactants to moles (mol). In this case, we can … Continue reading Determining Precipitate Yield (g) in Aqueous Solution
