The decomposition of the given compound, Pb(NO3)2, will yield 3 different simpler compounds which are lead oxide (PbO), nitrogen dioxide (NO2), and oxygen (O2). Based on the given chemical formula, the ionic component of the compound are Pb²⁺ and 2 ions of NO₃²⁻.
The phases of these compounds will have to be solid and aqueous.
Answer: %C = 63.5%, %H = 6.00%, %N = 9.3%, %O = 21.2%
The answer would be 1800. Why? bc if you're going 30 meters per second and trying to figure out how far you would go in a minute, you would multiply 30 x 60 bc there's 60 seconds in a minute. Giving you 1800 meters. hope this helped, have an amazing day :)
