An iron nail is placed in a solution of blue copper(II) sulfate. Over time, a brown solid appears and the solution becomes colourless. This is because copper and a solution of iron(II) sulfate ...

Electron dot structures or Lewis dot formula can be drawn if the molecular formula of the compound is known. The representation of molecules in Lewis electron dot structure or just a Lewis structure is in honour of the American chemist Gilbert Newton Lewis. Lewis dot structures also called electron dot structures are diagrams that describe the chem...
Lewis dot structures reflect the electronic structures of the elements, including how the electrons are paired. Lewis structures are a useful way to summarize certain information about bonding and may be thought of as “electron bookkeeping”. In Lewis dot structures each dot represents an electron. A pair of dots between chemical symbols for atoms r...
A Lewis Electron Dot Formula comprises one dot for every valence electron and an element’s symbol. Stages to articulate the electron dot formula are stated beneath. Note down a skeletal structure displaying a realistic bonding pattern by means of only the element symbols. Pick up every valence electrons from every atom and toss them into a make-bel...
A Lewis electron dot structure describes the bonding atoms, the number of bonds in the molecule, and the lone pairs left in the bonding atoms. The steps that must be followed while drawing a Lewis structure are listed below. 1. 1.1. 1.1.1. 1.1.1.1. 1.1.1.1.1. 1.1.1.1.1.1. First, the total number of valence electrons present in the molecule is calcu...
Problem-1: In terms of electron dot formulas, define the electron structure of the carbonate ion CO32-. Solution: One potential electron dot formula for the carbonate ion is Since all carbon-oxygen bonds are likely to be equal, the electron structure in resonance terms is shown below. Over the region of all three carbon-oxygen bonds, one electron p...

About this unit. Water can exist as ice, which is a solid; it can exist as liquid; or it can exist in the gaseous state as water vapour or steam. In this fifth unit of class 11, chemistry, we will learn more about these three physical states of matter particularly liquid and gaseous states. We learn about intermolecular forces, gas laws, ideal ...
Kinetic energy can’t be negative, although the change in kinetic energy. Δ K. \Delta K ΔK. delta, K. can be negative. Because mass can’t be negative and the square of speed gives a non-negative number, kinetic energy can’t be negative. Either something is moving and has positive kinetic energy, or it is not moving and has zero kinetic ...
Sep 10, 2018 · Mapping physical meaning onto symbols. As discussed in our page, How math in science is different from math in math, in science our symbols don't just stand for numbers, they stand for physical quantities. Here's a "biologically relevant" problem from a calculus class that is trying to be "biologically relevant" and missing some critical issues.
