Overview of Chemistry Terms The scientific study of matter's characteristics and behaviour is known as chemistry. Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, m...
What is a substance in chemistry? What are some metals on the periodic table? What is a pure substance in chemistry? What is chemistry? What is a metallic atom? What are the metal elements and non-metal elements involved in the chemical reaction: CaCl2 + AgNO3 -- Ca(NO3)2 + AgCl2 ...
A solvent (e.g., water) is something that serves to dissolve a solute, while a solute, such as NaCl, is something that dissolves within a solvent. In inorganic chemistry and also organic chcemistry, much time is spent in learning the relative solubility of compounds....
When 1.75 g of CaCl2 dissolves in 125 g of water in a coffee-cup calorimeter, the temperature increases by 2.44 C. What is the heat change per mole of CaCl2 dissolved in water? Assume that all the heat is absorbed by the water (c = 4.18 J/g C). ...
One of a very unique benefit of its presence is that it avoids thecorrosion of steel rebarsbecause of its chemical nature. Tri-calcium aluminate combines with chloride ions to form CaCl2 thereby decreasing the concentration of chloride responsible for erosion of steel reinforcement. However, this as...
What is the molar mass of Barium? Atomic Mass and Molar Mass The periodic table lists the atomic mass and molar mass of each element. The values are the same, but their units are different. Atomic mass has the units atomic-mass-units, or AMU. Molar mass is the mass of one mole of ...
Generally, liquid PAC products should be used in a short period of time (solid products have stable performance). , it can be stored for a longer time). Adding some inorganic salts (such as CaCl2, MnCl2, etc.) or macromolecules (such as polyvinyl alcohol, polyacrylamide,...
having both calcium and carbonate in your final water will boost your LSI, I can’t say for sure that this water will be safe against corrosion. Ultimately it depends on what your machine is made of: for more on this, check out myAMA on water chemistrywhere I discuss this in more ...
What is a nonelectrolyte in chemistry?Question: What is a nonelectrolyte? Nonelectrolytes: Chemicals that dissociate in water break into ions that form electrolytes. Electrolytes are classified as strong, weak, or non-electrolytes based on the amount of chemical that dissociates in water. Answer ...
In 0.03 mol/kg CaCl2(aq) solution the concentration of Cl-(aq) ions is [{Blank}]. What dissolved species are present in a solution of NaClO4? If you are given a 0.05 M solution of K_2CrO_4, what is the concentration of each type of ion in the solution? Aside from wat...
