Balanced equation
2Pb(NO₃)₂⇒2PbO+4NO₂+O₂
<h3>Further explanation</h3>
Given
Reaction
Pb(NO₃)₂⇒PbO+NO₂+O₂
Required
Balanced equation
Solution
Pb(NO₃)₂⇒aPbO+bNO₂+cO₂
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>
Answer:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Thermal energy is defined as the total kinetic energy of all particles in an object. Even though the cup of water has a higher temperature, the bathtub has more thermal energy because it contains much more mass of water compared to the cup.
The mass would still be the same 25.0 g but the volume would be bigger
