Class one has one division.
What is the electron dot formula for SF6?
The electron dot formula for SF6 would show 6 pairs of dots around the central Sulfur atom, representing the 6 Fluorine atoms bonded to it. The Sulfur atom will have 12 valence electrons around it in total.
What is the probability that a rolled dot cube will stop with exactly two dots on top?
The probability of rolling a dot cube and stopping with exactly two dots on top is 1/6, because there are 6 possible outcomes when rolling a dot cube (1, 2, 3, 4, 5, 6) and only one of those outcomes has two dots on top.
Can you connect 9 dots set in a three on three array with four lines?
Yes, you can connect 9 dots set in a three on three array with four lines by imagining the array as a square with a dot at each corner and one dot in the center. You would draw a line from the top-left dot to the bottom-right dot, another line from the top-right dot to the bottom-left dot, one line horizontally through the center dot, and one line vertically through the center dot.

What is the most dangerous classes of dangerous goods?
The most dangerous classes of dangerous goods are Class 1 (Explosives), Class 2 (Gases), Class 3 (Flammable Liquids), Class 4 (Flammable Solids), Class 5 (Oxidizing Substances and Organic Peroxides), Class 6 (Toxic and Infectious Substances), Class 7 (Radioactive Material), Class 8 (Corrosives), and Class 9 (Miscellaneous Dangerous Goods). Among these, Class 1 and Class 7 are often considered the most hazardous due to their potential for catastrophic incidents or long-term health risks. Proper handling, storage, and transportation protocols are essential to minimize the risks associated with these materials.
