Explanation:
HCH bond angle is ~110 degrees.
The answer is false.
That is the ticketing area is more secure than the area beyond the security check point is false rather than the area beyond security check point is more safe than the ticketing area.
There is more security in the area beyond security check point because of anti-terrorism actions .
There is less security on the ticketing area and more on security check point.
Answer:
Ka= 2.3 x 10^-11
Explanation:
so Ka x Kb = Kw where Kw=10^-14 at 25 degrees Celsius
plugging in Kb and Kw, we have
Ka x 4.4 x 10^-4 = 10^-14
solving for Ka,
Ka= (10^-14)/(4.4 x 10^-4)
Ka= 2.3 x 10^-11
Answer:
The Enthalpy of neutralization
Explanation:
The reaction of a base (KOH) with an acid (HCl) produce water and its salt (KCl) is called <em>Neutralization Reaction.</em>
This neutralization releases 57kJ/mol.
As the type of enthalpy is due the type of reaction. This enthalpy is:
<h3>The Enthalpy of neutralization</h3>
