An initial solution of HNO, is 15.4 M. How
much of the concentrated acid do you need to
make 200.0 mL of a new 3.50 M solution?

Here’s one way to follow the scientific method. place the missing steps in the correct position in the process

Brainliesttt me asap! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

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.)
