A.) desertification is when you remove all the trees and most of the plant life in an ares
Calcium reacts gently with water to give hydrogen and calcium hydroxide, which is only slightly soluble, thus slows down the reaction.
It will be assumed that hydrochloric acid used is a dilute aqueous solution.
However, calcium reacts with hydrochloric acid to give calcium chloride which is readily soluble in water, and hydrogen, being a typical reaction of relatively active metals with acids.
Ca(s) + 2HCl(aq) -> CaCl2(aq) +H2(g) ↑ + heat
The clues that it is a chemical reaction could be:
- formation of a new substance, gaseous hydrogen
- disappearance of a metallic solid in the solution
- heat formed during the vigorous reaction.
As silver is below hydrogen in the electrochemical series, it will not be expected to react with dilute hydrocloric acid. (however, it dissolves in oxidizing acid such as nitric acid, but not displacing hydrogen as a product).
Answer:
Explanation: Organic chemistry have a wide variety from compounds of the presence of two elements namely
Organic molecules comprises of multiple chains of carbon atoms with different lengths and because of the ability of carbon to bond with many elements, This produces a variety of compounds which no other atom or element can. The main variety of compounds exists in the combination of carbon and hydrogen forming hydrocarbons which are virtuall everywhere around us
