Answer(H2PO4- (aq) + OH- (aq) HPO4-2 (aq) + H2O (l) ) Question= Neutralization reactions typically occur between a strong acid and a strong base to produce a salt and water question When sodium carbonate (Na2CO3) dissolves in water‚ it partially ionizes. The carbonate (CO3-) ion takes up a hydrogen ion and forms

The prevalence of white-collar crime casts a long shadow over discussions in business ethics. One of the effects that has been the development of a strong emphasis upon questions of moral motivation within the field. Often in business ethics‚ there is no real dispute about the content of our moral obligations

Magnesium‚ an abundant mineral in the body‚ is naturally present in many foods‚ added to other food products‚ available as a dietary supplement‚ and present in some medicines (such as antacids and laxatives). Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body‚ including protein synthesis‚ muscle and nerve function‚ blood glucose control‚ and blood pressure regulation [1-3]. Magnesium is required for energy production‚ oxidative phosphorylation

Acid Base And Salt Acid Acids:- The word ‘Acid’ came from Latin word ‘Acidus or Acere’ which means sour. Sour taste is the most common characteristic of acid. Acid turns blue litmus paper red. There are many substances which contain acid and hence taste sour‚ such as curd‚ tamarind‚ lemon‚ etc. Types of Acids:- Acids are divided into two types on the basis of their occurrence – Natural acids and Mineral acids. Natural Acid:- Acids which are obtained from natural sources are called natural

In this lab it is hypothesized that every chemical reaction which was observed would fall under already set categories (that are: synthesis‚ decomposition‚ single displacement‚ double displacement‚ combustion and neutralization). Synthesis reactions occur when multiple reactants combine to produce a product (i.e. 2H2 (g) + O2 (g) 2H2O (l)). Decomposition reactions occur when a single reactant breaks down into multiple products (i.e. 2KCl (S) 2K (s) + Cl2 (g)). Single

Introduction The primary objective of this lab is to be able to determine the specific heat of a reaction by using a calorimeter. A calorimeter is a device used to determine the specific heat of chemical reaction or a physical change. The specific heat a reactions is used to refer to the amount of heat that is lost or gained when one gram of a particular substance increases or decreases by one degree Celsius. When a chemical reaction occurs in an open container most of the energy gained or lost
