Chemistry is the study of matter and the ways in which different forms of matter combine with each other
Chemistry is the study of matter. Our understanding of chemical processes thus depends on our ability to acquire accurate information about matter. Often, this information is quantitative, in the form of measurements. In this lab, you will be introduced to some common measuring devices, and learn how to use them to obtain correct measurements, each with correct precision. A metric ruler will be used to measure length in centimeters (cm).
Short Description:
The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"The Journal of Materials Research is proud to announce the 2019 Gordon E. Pike JMR Paper of the Year Award. This award recognizes excellence in advancing materials knowledge through written scholarship. This year’s honors go to a team of researchers from China and the US for their report on a new form of flexible and rechargeable supercapacitor wire, which was published in the September 14, 2019 issue of Journal of Materials Research. With the rapid growth of portable and wearable electronics, researchers face many important challenges. They’re tasked with fabricating devices that are smaller, lighter, and more flexible than ever—all while delivering the same or higher levels of performance. Wire-shaped supercapacitors are among the most promising technologies developed to address these challenges. These flexible devices store and deliver energy in the form of tightly wound fibers of electrochemically active materials, such as carbon nanotubes..."

The ACS (American Chemical Society) citation style guide uses color-coded citation examples to assist chemistry students in converting MLA and APA citations to the ACS citation style. The MLA and APA citation styles are widely used in college courses, and many students are familiar with those styles. This guide makes citation in chemistry courses simple by giving examples of frequently referenced resources.

this document contains usses of polymers in various parts of the automobile and respective examples with the requirement of material to make product and polymers selected with similar properties.
Learn more about ATP: how it stores energy, and how that energy is released when it's converted to ADP and phosphate. Created by Sal Khan.
Determine the enthalpy of the ATP reaction.
This video segment adapted from First Light explains why the highest peak in the Pacific, Mauna Kea, is an ideal site for astronomical observations. Featured are new telescope technologies that allow astronomers to explore the universe in more depth.

This segment from Swift: Eyes through Time traces the history military officers and engineers discovering a strange phenomenon in the sky that astronomers now know are gamma-ray bursts.
In this lab exercise, students practice correctly using measurement tools, recording data, calculating density, using significant figures, and exploring the concepts of accuracy and precision.
This unit of investigation is introduced using the anchoring phenomenon of a rocket launch. Students investigate the concepts of what is fuel, why some materials react and others do not, the role energy plays in the rearrangement of atoms, and where does the energy to do this come from and finally what makes the rocket lift off if fire itself is not causing this.
In this activity, students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several things that engineers are doing to reduce the effects of acid rain.
How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?
