Christmas Trivia

Happy Tuesday and Merry Christmas to those who celebrate this holiday! If you’re anything like me, you started singing Christmas carols and getting out your lights the day after Halloween. And if you’re like me, you view Thanksgiving as the “halfway to Christmas” holiday. These days, it seems like Christmas gets recognized for nearly 3 months out of the year, but I enjoy every minute of it. To me, it’s a wonderful time of the year – the holly, ornaments, carols, cookies, wreaths, lights and garlands – I can’t get enough.

Happy Tuesday! The final question for 2018 focuses on the EPA 500 Series methods that have been developed to quantify organic contaminants in drinking water. For those unfamiliar, EPA Method 525.2 outlines the extraction and quantification of organic compounds in drinking water. The EPA eventually revised the method and released Method 525.3. The updated revision incorporates a number of changes to improve the extraction and quantification of drinking water contaminants. Continue reading Tuesday Trivia – December 11, 2018

Tuesday Trivia – Answer for November 13, 2018

Just a reminder of last week’s post:

The United States has been using pesticides for decades to protect crops and livestock from disease, mold, insect damage and many other types of pesky organisms. According to the United States Geological Survey (USGS), roughly 540 million pounds of pesticides were used in 1964. How many pounds of pesticides were being used across the nation by 1993?

Answer: 1.1 billion

Technically, the term “pesticide” is a somewhat generic term to describe a substance that controls pests. Based on that definition, pesticides include herbicides, fungicides, insecticides and many more chemical solutions. Given the increase in the U.S. population between 1964 and 1993, and the growth in the number of viruses, fungi, bacteria and other organisms that could endanger the health of our crops and livestock, it’s not surprising that our use of pesticides rose significantly over that period of time.

Tuesday Trivia – October 30, 2018

On the eve of Halloween, I find myself reminiscing about how I celebrated the holiday as a child. I remember the excitement of getting dressed up as my favorite animal or TV character, and bringing home a sack full of candy after a successful night of trick or treating. I also remember doing fun activities like making glow in the dark slime or ghost rockets.

Tuesday Trivia – Answer for October 16, 2018

During National Chemistry Week, we’re continuing our trivia with an “Out of this World” focus.

Just a reminder of last week’s post:

An interesting study at the University of Georgia revealed the major component of interstellar clouds to be:

(a) Hydrogen and helium atoms
(b) Mothballs
(c) My dreams
(d) Ammonia
(e) Carbon Monoxide

Answer: mothballs

A handful of researchers measured infrared emission from some interstellar clouds and found a measurable concentration of gas-phase naphthalene, which is the main compound in mothballs. Just to clarify, naphthalene is pretty flammable so modern day mothballs are primarily composed of 1,4-dichlorobenzene, but older mothballs contained lots of naphthalene.

It’s only the third day of National Chemistry Week so you have 4 more days to celebrate the fact that chemistry is out of this world!
