A set is always represents by the capital later of the alphabet and the elements of the set are written in the middle braces and separated by the commas. The intersection set C of two given sets A and B is the set that have the elements which are common in the...
Compound microscopes in particular work using an arrangement of lenses for refracting light to zoom in on cells and other specimens to take you into a micro-sized world. A microscope is called a compound microscope when it consists of more than one set of lenses. Compound microscopes, ...

If one mole of a substance has a mass of 58.44 grams, how many moles are in 1.0 grams of the substance? Molar Mass: Molar mass refers to the mass expressed in grams of all the elements that compose a substance. It can be simply described as t...
How many moles are in 11.3 grams of {eq}H_2 {/eq}? Molecular Compounds: Water is an example of a molecular compound that exists in terms of discrete molecules. A water molecule contains non-metal atoms known as H and O. These elements are combined by covalent bonds. ...
How to make many elements as ONE element for Gradient tool? Joninen Participant , Feb 24, 2019 Copy link to clipboard Hi! I've been useing Pathfinders Trim command when joining elements together. But when useing the Gradient tool for that trimmed element, it works ...
The root mean square is used in many engineering and statistical applications, especially when there are data points that can be negative. \(\begin{array}{l} X_{rms}=\sqrt{\frac{x_{1}^{2}+x_{2}^{2}+x_{3}^{2}….x_{n}^{2}}{n}}\end{array} \) ...
The number of ions in a compound depends on the structure of the compound and the oxidation states of the elements within the compound. An element's oxidation state is the number of electrons that an atom possesses or lacks relative to the number of protons in its nucleus. This determines ...
(light reflection/refraction), and thermal properties. A microscopic view of the elements and molecules in a solution can help provide a better idea of how molecules behave when they are in close proximity with other compounds, and can help explain some of the properties of so...
How are elements classified in the periodic table? How does the number of atoms change during a chemical reaction? How many naturally occurring elements are there? What are the types of chemical reactions? What is formed when two or more atoms join together chemically?
