If A Reaction Takes 10s To Go To Completion At 0°C, How Long Will It Take To Go At 100°C?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

The mass of a neutron is equal to the mass of a proton plus the mass of an electron. true or false false true

The element that has the greatest electronegativity is
