Balanced equation

2Pb(NO₃)₂⇒2PbO+4NO₂+O₂

<h3>Further explanation</h3>

Given

Reaction

Pb(NO₃)₂⇒PbO+NO₂+O₂

Required

Balanced equation

Solution

  • Give coefficient

Pb(NO₃)₂⇒aPbO+bNO₂+cO₂

  • Make equation

Pb, left=1, right=a⇒a=1

N, left=2, right=b⇒b=2

O, left=6, right=a+2b+2c⇒6=1+2.2+2c⇒6=5+2c⇒1=2c⇒c=1/2

The reaction becomes :

Pb(NO₃)₂⇒PbO+2NO₂+1/2O₂ x2

<em>2Pb(NO₃)₂⇒2PbO+4NO₂+O₂</em>

tankabanditka [31]
The Earth, Mars or Jupiter should be denser than the Sun. Density is defined by mass and volume — components of object or matter. Although the sun is huge, it’s component is made up of mostly gas (hydrogen and helium). While Earth, though smaller than the Sun, contains heavier elements such as iron, sulfur, rocks, sediments, granite, basalt and water. Mars (composed of rocks and nutrients) and Jupiter (contains gases and compounds) as well are denser when compared to the Sun’s density. Referencing to our basic understanding of matter: solid and liquid should be heavier than gas.
