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:
0.30 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 25.0 mL
M₂ = 0.117 M
V₂ = 65.5 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
Putting the respective values -
M₁ * 25.0mL = 0.117 M * 65.5 mL
M₁ = 0.30 M
Answer:
The chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.
I am sorry if this isn't the answer you were hoping for so if it isn't, I greatly apologize.
I can change it to the correct one if you want

<span>The average molar bond enthalpy of the carbon-hydrogen bond in a CH4 molecule is 416 KJ/mol.
(+716.7 + (4 x 218) - (- 74.6) ) / 4
= + 1663.3 / 4
= 416</span>
Answer:
Screening for the presence of drugs in serum and urine using different separation modes of capillary electrophoresis. The most common mode is capillary zone electrophoresis (CZE), in which charged analytes migrate in a buffer under the influence of an electric field.
