Answer: Double replacement reaction
Explanation:
use ideal gas equation PV=nRT
find P fro the above equation all other are available in the your question.
V= volume
T= temperature
n= moles of gas
R is constant = 8.314 4621(75). J K−1 mol−1
Answer:
1) 3-methylpentane 2) Butyne
Explanation:
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>
