What is the gram formula mass of caso4.2h2o?

What is the mass of the formula gram of case4.2h2o?Answer 1So Ca = 40 g/mol S = 32 g/mol O = 16/mol H = 1 g/mol molar mass of CaSO4.2H2O = [(40) + (32) + (16 × 4) + (2 × 1 × 2) + (2 × 16)] = 172 g/moleanswer 2Answer: The gram mass formula is 172 g/mol Explanation: As we know, Molar mass of calcium (Ca) = 40 g/mol Molar mass of sulfur (S) = 32 g/mol Molar mass of oxygen (O ) = 16 g/mol Molar mass of hydrogen (H) = 1 g/mol We now need to calculate the mass from the gram formula of In , there is 1 atom of calcium, 1 atom of sulfur , 6 oxygen atoms and 4 hydrogen atoms. The formula gram mass of = Therefore, the formula gram mass of is, 172 g/molanswer 3a. The mass of formula gram of CaSO4.2H2O is equal to 172 grams/mol b. The mass percentage of H2O in CaSO4.2H2O is 20.9% c. The molecular formula of naphthalene is C10H8 d. The total number of moles in 80.0 grams of C2H5Cl is 1.24 moles e. 4.76 moles of Na3PO4 contain 780.64 grams of Na3PO4 Explanation: RMM = relative molecular mass. Read more

The chemistry of living systems representing all chemical reactions is called

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?

Product H* in solution.Answer 1D.Product H* in solution.answer 2Jehdhdhdhehejejeanswer 3Elijah is almost right. he just understood backwards. The correct answer is that it demonstrates that elastic potential energy transforms into kinetic energy.

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.
