Since the two differ in molecular structure, their
recognition profiles for the two substances are very different. Substance
identification is a procedure by which the distinctiveness of the substance is recognized.
Octanoic acid is the eight-carbon straight chain fatty acid while octanol
is a fatty alcohol.
Answer:
An ignition coil can fail due to a high voltage puncture of its body, or an open primary or secondary winding. A few are killed by overheating when the control side of the primary side develops a short to ground. Something as simple as badly worn spark plugs will increase the demand from the coil, and eventually lead to failure.
But if I were to discuss the current leading cause of ignition coil replacement, I would have to say misdiagnosis and bad internet information. This is especially true of modern “coil on plug” systems. Often, the actual coil is fine, and the only damage is the replaceable spark plug boot.
I've seen countless examples of online “advice” to start with replacing all spark plugs and coils at the suggestion of any power loss or hiccup. Then the car owner purchases the cheapest set of coils that they can find. Not only is the initial problem still present , but they likely WILL have a future misfire due to poor quality parts selection. All misfires are not caused by coils and spark plugs.
Explanation:
In neutralisation reactions, acid and base reacts. Acid dissociates to give out H⁺ ions and bases dissociate to give out OH⁻ ions. These H⁺ ions and OH⁻ ions react to form H₂O molecules.
and the anion from the acid dissociation and cation from base dissociation form salts.
therefore in a neutralisation reaction acid reacts with base to form water and the corresponding salt
Mg(OH)₂ + 2HNO₃ ---> Mg(NO₃)₂ + 2H₂O
HCl + NaOH ---> NaCl + H₂O
I believe the answer is d
Answer:3480s⁻¹
Explanation:We can solve the following problem using the Arrhenius equation.
Arrhenius equation is given by:
A=Pre-exponential factor or frequency factor
Ea=Activation energy
R=Ideal gas constant
T=Temperature
K=Rate constant
From the Arrhenius equation we can see that the rate constant K is related with the activation energy and frequency factor.
In the question we are given with the following data:
Ea=42KJ/mol=42x 1000 J/mol
A=8.0×10¹ per second
T=298K
R=8.314J/K mol
when we substitute these given values in Arrhenius equation
K=3480s⁻¹
The value of rate constant obtained is 3480s⁻¹.
