The equation below shows the decomposition of lead nitrate. how many grams of oxygen are produced when 4.60 g no is formed? pb(no3)2 (s) → pbo (s) + no2 (g) + o2 (g) show all the work

            0.8 g of O₂

Solution:

             The balance chemical equation is as follow,

                         2 Pb(NO₃)₂      →     2 PbO + 4 NO₂ + O₂

According to equation,

     184 g (4 moles) NO₂ is produced along with  =  32 g (1 mole) O₂ gas

So,

    4.60 g NO₂ when formed will produce along  =  X g of O₂

Solving for X,

                     X  =  (32 g × 4.60 g) ÷ 184 g

                     X  =  0.8 g of O₂

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
