Solutions of alkali metals in liquid ammonia areintensely colored and good conductors of electricitydue to the presence of solvated electrons (e−, NH3), which are not attached to single atoms. Why ammonia is highly soluble in water? It is highly soluble in water. The high solubility of amm...
Explain why the melting point and boiling point of alkali metals are low. Why do metals only form ionic compounds while metalloids and nonmetals form ionic and covalent compounds? Why do metals conduct heat and electricity? What happens when alkali metals react with molecular hydrogen? Why are m...
Why does silver become tarnished (react with air), but gold doesn't? Give two reasons why F_2 is the most reactive of the halogens. Explain why alkali metals produce a colored flame? Why do transition metals generally give colored compounds in a solution?
Step 2: Definition of Alkaline Earth MetalsThe term "alkaline earth metals" refers to the fact that these metals produce alkaline (basic) solutions when they react with water. The word "alkaline" comes from the Arabic word "al-qaly," which means "ashes of saltwort," and "earth" refers to...
The team wanted to try the same approach with water instead of ammonia, but faced a challenge: alkali metals tend to react explosively when mixed with water. The solution was to design an experimental set-up that would dramatically slow the reaction so that it would not be explosive. ...
Soap is a mixture of fat or oil, water, and an alkali, or basic salt. The ancient Babylonians are credited with being the first people to make soap. Their recipe for animal fats, wood ash and water has been found carved into clay containers dating back to 2800 B.C., according to ...
[16]) and that the second ionization potential of silver (which partly governs the formation of its compounds) approaches 21.5 eV in the gas phase, and it is by far the largest value among all metals (except, obviously, the alkali metals, which do not adopt divalent state in chemical ...
How does metallic bonding structure explain why metals are malleable? Why is barium more reactive than magnesium? Explain why group 7 elements react in a similar way with iron. Explain why the melting point and boiling point of alkali metals are low. ...
Explain why group 7 elements react in a similar way with iron. You are cooking spaghetti in water you have salted with NaCl. You notice that when the water boils over, it causes the flame of the gas burner to turn bright orange. How wou...
What happens when sodium chloride is added to boiling water and why? What happens when alkali metals react with molecular hydrogen? How does the law of conservation of mass affect the cleaning of dirty copper nails with acetic acid? What do y...
