Periodic Videos (also known as The Periodic Table of Videos) is a video project and YouTube channel on chemistry.It consists of a series of videos about chemical elements and the periodic table, with additional videos on other topics in chemistry and related fields.
Braun had been making videos, mainly tutorials, for fun since his teenage years, creating a YouTube channel on March 10, 2014. His first video was uploaded on March 24, 2014, and many of his early videos were recordings of his projects as a laboratory technician or at his parents' garage, with them later being filmed at his industrial-grade laboratory.

The leftmost or largest digit position among the last significant figures of these terms is the ones place, so the calculated result should also have its last significant figure in the ones place. The rule to calculate significant figures for multiplication and division are not the same as the rule for addition and subtraction.
MinutePhysics is an educational YouTube channel created by Henry Reich in 2011. The channel's videos use whiteboard animation to explain physics-related topics. Early videos on the channel were approximately one minute long. [2] As of March 2024, the channel has over 5.7 million subscribers.
Instead, the slow step involves two molecules of NO 2. A possible mechanism for the overall reaction that explains the rate law is: 2 NO 2 → NO 3 + NO (slow) NO 3 + CO → NO 2 + CO 2 (fast) Each step is called an elementary step, and each has its own rate law and molecularity. The sum of the elementary steps gives the net reaction.

While at the interface of physics and chemistry, chemical physics is distinct from physical chemistry as it focuses more on using physical theories to understand and explain chemical phenomena at the microscopic level, such as quantum mechanics, statistical mechanics, and molecular dynamics. Meanwhile, physical chemistry uses a broader range of ...
