The formula for K+ and S-2 is K2S because you need 2 potassium ions to balance out the sulfide ion
Answer:
rocks main constituent is calcium carbonate, which produce carbon dioxide and calcium oxide (quick lime) upon heating
Answer:
Explanation:
Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), and iodine monobromide (IBr). Covalent bonding between hydrogen atoms: Since each hydrogen atom has one electron, they are able to fill their outermost shells by sharing a pair of electrons through a covalent bond
Moles of NH3 = mass of NH3/molecular mass of NH3 = 1.7/17= O.1 MOLES.
Answer is "The salt Bridge"
Explanation:
During the spontaneous reaction in Voltaic Cell, the balance of ions get disturb due to increase in concentration of negative charge in one half cell and positive charge in another. In order to keep balance the charges in cell, concentration of ions on both sides and overall neutrality of the system, a U-shape tube filled with inert electrolyte is connected to both half cells. The electrolyte migrates in such a way that the charges of solution in cells keep constant.
