The process of converting sugar into alcohol by yeast is called: MCQ with Answer and Explanation

Explanation:
Na+, Mg2+, Al3+, and F- are isoelectronic species, each having 10 electrons. For isoelectronic ions, the ionic radius decreases as the nuclear charge (number of protons) increases because the greater positive charge pulls the same number of electrons closer. F- has the lowest nuclear charge (9), so it has the largest radius.

Explanation:
Liquefied Petroleum Gas (LPG) consists primarily of propane (C₃H₈) and butane (C₄H₁₀) liquefied under pressure. A strong-smelling mercaptan is added as odorant to detect leaks. CNG is mainly methane. LPG is used for cooking and as automotive fuel (autogas). It has higher calorific value than natural gas. It is heavier than air, so it settles in low areas, posing a safety hazard if leaked.

Explanation:
Atomic number is the number of protons, which is 17 for all chlorine atoms. Mass numbers differ due to different neutrons (18 and 20). Isotopes have same atomic number, different mass number.
