What is molar mass in chemistry? Physical Properties of Elements: Every element in the periodic table has unique characteristics and physical properties. These properties govern how elements behave in nature, including how they interact with their surroundings and other chemicals. Answer and Explanation...
Mass is defined as the amount of matter in an object while weight is defined as the force exerted by an object. SI unit of mass is kilograms while SI unit of weight is Newtons. Object weighing 1 kg mass will have 9.8 N weight.
If asked "What is an isotope ?" in GCSE Chemistry, a more detailed answer is required using one of the definitions below:Definitions of an isotope: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Another way to say the same ...
In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio ofsolutein a solution to eithersolventor totalsolution. Concentration is usually expressed in terms ofmassper unitvolume. However, the solute concentration may al...

By inspection, you can see this equation is not balanced because mass is not conserved. There are more oxygen atoms in ozone (O3) than there are in oxygen gas (O2).You cannot calculate mole ratio for an unbalanced equation.Balancing this equation yields: ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
Wet Chemistry:Wet chemistry lab techniques include colorimetry, gravimetry, and titrimetry, which may filter, distill, or dissolve samples to extract metals. Chemical analysis is the conventional method of element analysis using laboratory beakers and flasks to manipulate a sample to identify a single...
