How does the absorption and release of energy affect temperature change during a chemical reaction?

A 1-gram sample or a compound is added to 100 grams of H2O(l) and the resulting mixture is then thoroughly stirred. Some of the compound is then separated from the mixture by filtration. Based on Table F, the compound could be(1) AgCl (3) NaCl

(2) CaCl2 (4) NiCl2

Answers

The answer is AgCl or Silver Chloride. Silver chloride is a biological compound with the chemical formula of AgCl. This white crystal-like rock-solid is well recognized for its little solubility in water. Upon light or heating, silver chloride transforms to silver (and chlorine), which is gestured by greyish or purplish coloring to other samples.

True or false when elements chemically combine they usually form compounds that have properties that are similar to those of the uncombined elements

Answers

The statement is False, because compound made up of elements which may have different properties. water is made up to oxygen i.e. gas and hydrogen which is also a gas, while water is a liquid and a good solvent.

What are the characteristics of water  ?

Water can be amphoteric in nature, as it act as both acid as well as a base, highly viscous in nature due to the force of attraction exists between molecules.

Water can be used in  Redox reaction as it help to get dihydrogen molecules quite easily, the dielectric constant of water is also high, form many different connections and attachments with other chemical compounds known as hydrates.

A substance show the normal behavior when it  reacting to heat, like that compounds expand after exposed to heat and decreasing their density, and after some time their density increases, and matter contracts when cooled, while in case of water this property is opposite.

Below  the temperature of   4 degrees Celsius the water  behaves ordinarily, however when it is cooled further, its unusual properties are being observed.

when water cooled, the density slowly increases, further cooled down leads to decrease in the density of water and the matter expands, which is called as the anomalous property of water occurs between temperatures of 4 degrees Celsius to 0 degrees Celsius.
