The February ChemQuiz.net newsletter is out with lots of NEW stuff to announce: a quiz timer, Beer-Lambert Law problems, font options for your assignments, answer explanations on the Naming Compounds Quiz, and more! #chemed #iteachchem mailchi.mp/chemquiz.net...
A screenshot from the Calorimetry Quiz on ChemQuiz.net shows the new timer feature as a partially colored green ring in the upper right corner, with the time "6:02" displayed below the ring and a pink arrow pointing at the ring A screenshot from the ChemQuiz.net Dashboard shows a new "Font to use for questions" option on the Assignment Settings page that lists the following fonts: Arial, Consolas, Courier New, Garamond, Georgia, Helvectica Neue (default), Times New Roman A screenshot from the Concentrations & Colligative Properties of Solutions Quiz on ChemQuiz.net shows an example of the new Beer-Lambert Law problems, which reads "A 7. x 10^-5 M solution of NADH with a molar absorptivity of 6200 M^-1 cm^-1 at 340 nm is measured in a spectrometer using a 1.00-cm cuvette. What is the absorbance of this solution?" A screenshot from the ChemQuiz.net Dashboard shows an answer explanation from the Naming Compounds & Calculating Molar Masses Quiz for that reads: "iron (II) acetate The first ion (iron) is a metal, so use the ionic compound formula rules. Start by writing out both ion formulas: Fe C2H302 Then, determine the charge for each ion. The Roman numeral for iron is (Il), so its charge is 2+. The charge for acetate ion is always 1-. Write these two ion formulas together with their respective charges: Fe^2+ C2H3O2^- Since the ion charges are not equal but opposite, you will need to balance them out to make a neutral compound. Copy the charge from the positive ion (2) so that it's to the right of the negative ion: Fe^2+ C2H3O2^- Because acetate is a polyatomic ion, put parentheses around it so that the multiple subscripts aren't confusing: Fe^2+ (C2H3O2^-)^2 Rewrite the final formula without the charges:"

Just added a new feature to most of the quizzes - pop-up periodic table! If your students happen to misplace their periodic table or you've activated tab-switch detection on an assignment, they can now use this instead. The pop-up calculator works alongside it, too! #chemed #iteachchem
A screenshot from ChemQuiz.net shows the new pop-up periodic table feature, which displays all of the elements with their element numbers, symbols and masses as well as different colors for each category (metals, metalloids, nonmetals and unknowns) A screenshot from ChemQuiz.net shows the new pop-up periodic table feature when the mouse is hovering over the square for element 26, which has expanded and is showing the element name "iron" instead of its element symbol A screenshot from ChemQuiz.net shows the new pop-up periodic table feature alongside the existing pop-up calculator feature

I was looking for a clean and simple periodic table that was easy to read with a fixed-width serif font that clearly differentiated between lowercase L, uppercase i, and 1. I couldn't quite find what I wanted, so I made my own! 0.001 precision here #chemed #iteachchem docs.google.com/document/d/1...

Just added the Coulomb's Law Quiz to ChemQuiz.net! Borrowed from PhysQuiz.net, the quiz now features diagrams and a new question type to calculate the force between an atom's nucleus and its outermost electron. Check it out & let me know what you think! chemquiz.net/cou #chemed #iteachchem #chemsky
A screenshot from the Coulomb's Law Quiz at ChemQuiz.net (https://chemquiz.net/cou/) shows a diagram of a polonium nucleus and its outermost electron with the question, "The atomic radius of polonium (Z = 84) is 1.35 × 10^-10 m. What is the magnitude of the electric force on its outermost electron?" A screenshot from the Coulomb's Law Quiz at ChemQuiz.net (https://chemquiz.net/cou/) shows a diagram of an iodine nucleus and its outermost electron with the question, "The nucleus of iodine (Z = 53) exerts -9.22 × 10^-7 N of force on its outermost electron. What is the atomic radius of iodine?" A screenshot from the Coulomb's Law Quiz at ChemQuiz.net (https://chemquiz.net/cou/) shows a diagram of a polonium nucleus and its outermost electron with the question, "Two charged particles, q1 = 3 × 10^-6 C and q2 = -1 × 10^-7 C, are arranged in such a way that they each experience -830 N of force. What is the distance between them?" A screenshot from the Coulomb's Law Quiz at ChemQuiz.net (https://chemquiz.net/cou/) shows a diagram of a polonium nucleus and its outermost electron with the question, "Three charged particles are placed in a line. The first particle has a charge of -7.2 x 10^-5 C and is found to the left of the other two. The second particle has a charge of 8.60 × 10^-4 C and is 1.90 x 10^-5 m to the right of the first particle. The third particle has a charge of 3 × 10^-6 C and is 7.0 × 10^-5 m to the right of the first particle. What is the magnitude of the force on the third particle?"
