Why does benzoyl chloride react preferentially with an amine rather than Na2CO3 or water? Give two reasons why F_2 is the most reactive of the halogens. What are the physical and chemical properties of chlorine? Why metals react more vigorously in acids than in water? Can sodium chloride and...
Explain why calcium is more reactive than magnesium yet they are in the same chemical group. Explain the way in which atoms are held together in a chemical compound. What are the differences between physical and chemical properties in Chemistry?
Explain (i) Why alkali metals are normally kept in kerosene oil. (ii) Why alkali metal impact colour to the flame? (iii) Explain, why lithium chloride h
Take the first element. Hydrogen has one electron in its outermost shell so you might assume it belongs exactly where it is, in group 1 above lithium and sodium, which also have one electron in their outermost shell. Yet hydrogen is a gas, not a metal, so its properties don’t f...
Sodium is a metal element, which means it is more prone to lose electrons than gain them. So sodium becomes a positive ion or cation. Because of... Learn more about this topic: Ionic Bond | Definition, Properties & Examples from
Why lattice energy of lithium chloride is more exothermic than that of sodium chloride? Why does NH_3 have a lower boiling point than H_2O? Briefly explain why the solubility of most salts increases with increasing temperatures. Why is it necessary to dry the purified acetanilide before takin...
c) lithium and sodium. d) germanium and arsenic. e) argon and bromine.Name the four common halogens and tell the normal phase of each. Which one is the most reactive of all elements?What do the members of the noble gas family have in c...
Why are metals more reactive in acids? Sodium metal is extremely reactive with chlorine gas. Is this a physical property or a chemical property? Explain. What is/are the forms in which sulfur and chromium can be found? Explain your answer. Why do elem...
Why potassium is more reactive than sodium Why do elements in the same group of the periodic table have similar properties? Why does metallic bonding only occur between metals? Why do halogens have high ionization energy? Why does chlorine have high ionization energy but forms an ion relativ...
Lithium hydroxide, like sodium hydroxide, becomes contaminated when exposed to air. What is the source of this contamination? What reactions take place? 1) Methanol and toluene are flammable liquids whose vapor pressures at 68 F (20 ^oC) ...
