Substance which is found in dried up lakes of Tibet and California is_______________?
Correct answer: A. Tincal
- A. Tincal
- B. Boric acid
- C. Calcium carbonate
- D. Colemanite
Explanation
Tincal, or natural borax, occurs in evaporite deposits and dried-up lake beds, including those of Tibet and California. Students may choose colemanite because it is also a boron mineral, but colemanite is a calcium borate rather than the borax mineral called tincal.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
