A 31.5 mL aliquot of H2SO4 (aq) of unknown concentration was titrated with 0.0134 M NaOH (aq). 23.9 mL of base was required to reach the titration endpoint. The concentration (M) of the acid was .

there are two significant digits.

alchemy had no scientific methods of study, appeal to mysticism and fantasy, knowledge of chemistry and physics was modest at that time. alchemy was – but as new rules were discovered it either morphed into chemistry or became “unscientific”.

I believe the answer is balance! I hope my answer has you 🙂

The chemistry of living systems representing all chemical reactions is calledAnswer 1The chemistry of living systems which represent all chemical reactions is called metabolism. Metabolism is defined as a set of all chemical reactions within an organism. The objectives of metabolic processes are to convert food energy into energy necessary for cellular processes, to synthesize the constituent elements of proteins, lipids, nucleic acids and certain carbohydrates (macromolecules) and to eliminate nitrogenous waste products. Catabolism and anabolism are part of metabolism that work together to maintain functions within the cell.Catabolic processes (breakdown of macromolecules) are necessary for the release of energy (usually in the form of ATP) which is then used in the anabolism-synthesis of compounds needed by the cell.answer 2I needanswer 3what is the complaint?

What is the total number of valence electrons in a germanium atom in the ground state?

What is the total number of valence electrons in a ground state germanium atom? (1) 22 (3) 32(2) 2 (4) 4Answer 14+ Explanation: Germanium, an element of the fourth group of the periodic table, has a valence of 4, ie 4 electrons in its outermost shell.answer 2D.4 Explanation: The periodic table of elements shows Ge, Germanium, with an electron configuration of 2-8-18-4. Valence electrons are the electrons of the outermost principal energy level of an atom. Germanium has 4 valence electrons.answer 3The atomic number Ge is 32 and the condensed electron configuration is - [Ar] 3d¹⁰ 4s² 4p² valence electrons are electrons in the outermost energy shell involved in chemical bonding the number of electrons in the 4th energy shell is 4 electrons by definition valence electrons are electrons in the outermost energy layer of the energy layer The outermost layer of Ge is the 4th energy layer, so the valence electrons of a ground-state germanium atom are located in the (4th) fourth layeranswer 4Fourth shell. I hope this helps you.Answer 5It would be on the fourth shell.Answer 6The valence electrons of a ground state germanium atom are located in the fourth shell.Answer 7The answer is (4) – 4.
