Answer:
— Molten Potassium Chlorate + sugar (gummi bear) ->
Answer:
liquid's heat of vaporization = 38.4 kJ/mol
Explanation:
given data
vapor pressure P1 = 6.91 mmHg
at temperature = 0 °C = 273.15 K
boiling temperature = 105 °C
solution
for vapor pressure and temperature we get here
P2 = 760.0 mmHg
T2 = 68.73°C = 378.15 K
we use here the Clausius-Clapeyron Equation that is
ln = .................1
put here value
In
solve it we get
x = 38445 J/mol
liquid's heat of vaporization = 38.4 kJ/mol
Answer:
The protonated form is predominant when aspirin is absorbed more readily. The ratio of conjugate base to acid is 1 to 100.
Explanation:
Aspirin is more readily absorbed when it is protonated, that is when pH is lower than pKa (<em>more H⁺ available in the medium</em>). We can confirm this using Henderson-Hasselbalch equation for pH = 1.5:
When aspirin is absorbed more readily the ratio of conjugate base to acid is 1 to 100, being the acid the <em>predominant</em> form.
Answer:
Explanation:
Hello.
In this case, given the described reaction, the formation of nitric acid turns out:
Since two hydrogen atoms are present at the reactants we balance it as follows:
In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:
Best regards!
Answer:
Hurricanes cover large areas typically hundreds of miles across. Tornadoes are small in meteorological terms, often affecting less than a square mile of an area.
Explanation:
Hurricanes cover large areas typically hundreds of miles across. Tornadoes are small in meteorological terms, often affecting less than a square mile of an area. A hurricane is a large rotating storm with high speed winds that form over warm waters in tropical areas. Hurricanes have sustained winds of at least 74 miles per hour and an area of low air pressure in the center called the eye. The eye of a hurricane usually only lasts for a day or two before a new eye forms and takes its place. For tornadoes, however, the three sizes are: weak, strong, and violent. Their size is based on how large the tornado is as well as the time that the tornado lasts and how it compares to the Enhanced Fujita Scale.
