Answer:
which produces hydrogen ion in water, called acid. A substance which produces hydroxide ion in water, called base. According to Bronsted-Lowry theory, an acid is proton donor and base is proton acceptor. Actually, Arrhenius theory is limited only to the aqueous solution.
Explanation:
Chemical formulas for ionic compounds are written in lowest common multiples of the charges of each ion. This is true unlike covalent compounds where the transformation to lowest common multiple is not applicable such that this reflects to the naming of covalent compounds using prefixes mono-, di-, tri-, tetra-, etc. Answer is a.
Answer:
Here's what I get.
Explanation:
(a) F, Cl, Br, and I are called halogens (salt formers)
(i) They are placed in Group 17, the Group just before Group 18 (the noble gases), because they need just one more valence electron to get a noble gas electron configuration.
(ii) At room temperature, iodine is a lustrous, purple-black solid that melts to form a deep violet liquid at 114 °C.
