Answer:

394mL

Explanation:

the molecular equation is

Pb(NO3)2 + 2 HI = PbI2 + 2 HNO3

the ratio between Pb(NO3)2 and HI is 1 : 2

moles HI required = 0.700 x 2 = 1.40

volume HI = 1.40 mol / 3.550 mol/L=0.394 L = 394 mL

Correctly complete the following about how light waves are arranged on the electromagnetic spectrum. The _____ of the waves ____
MrRa [10]

P.S. most textbooks should show that radiowaves are on the left side and UV or gamma rays on the right - if it's opposite in your one then just replace the second word with their appropriate antonyms.
