Use dimensional analysis to perform the following calculations. Show K, U, and plan! Use correct sig figs and units! 3. How many mL are equal to .0024 L?
4. How many km are equal to 1.55 x 10^4 m?
5. How many mm are equal to 4.75 x 10^-2 m?

Idon't really understand this can you me and show your work.☺☺[ chemistry b] subject [ electron transfer in lonic bonds]grade( 12)

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.)

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3
