which reaction is more vigorous calcium metal for sale

Chemistry 1.3.2 Group 2 Flashcards | Quizlet

When barium metal is added to water, the reaction taking place is much more vigorous than with calcium. Explain why barium is more reactive than calcium (4) Barium atoms are larger; have more shielding; which outweighs increase in nuclear charge; barium electrons therefore lost more easily.

Edurite - Aluminum Hydrochloric Acid Reaction

Question:When aluminum foil is placed in hydrochloric acid, nothing happens for about 30 seconds or so.This is followed by vigorous bubbling and the eventual disappearance of the foil. Explain these observations. Answers:The reaction that occurs is 2 Al + 6 HCL ---> 2 AlCl3 + 3 H2 So the bubbling gas is hydrogen.The reason there is a slight delay is that aluminum forms a very thin oxide layer

Carbonate Minerals - ThoughtCo

Aragonite and calcite are polymorphs of calcium carbonate. It is harder than calcite (3.5 to 4, rather than 3, on the Mohs scale) and somewhat denser, but like calcite it responds to weak acid by vigorous bubbling. You may pronounce it a-RAG-onite or AR-agonite, though the majority of American geologists use the first pronunciation.

Reducing agent - Revolvy

A reducing agent (also called a reductant or reducer ) is an element (such as calcium) or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons, it is said to have been oxidized. If any chemical is an electron donor (reducing agent), another must be an electron recipient ( oxidizing agent ).
