Which element at 101.3kPa and 298 K?
At 101.3 kPa and 298 K, the element present is likely to be oxygen (O2) due to its high natural abundance in the atmosphere and its physical properties at that temperature and pressure.
Which compound is formed from its elements by an exothermic reaction at 298 K and 101.3 kPa?
Carbon dioxide (CO2) is formed from its elements (carbon and oxygen) by an exothermic reaction at 298 K and 101.3 kPa.
How do you convert 298 degrees Fahrenheit to kelvin?
To convert Fahrenheit to Kelvin, you can use the formula K = (F - 32) x 5/9 + 273.15. Plugging in 298 degrees Fahrenheit gives you K = (298 - 32) x 5/9 + 273.15, which equals approximately 425.37 Kelvin.
What is the Kelvin temperature of 25 degree Celsius?
To convert Celsius to Kelvin, add 273. So, the Kelvin temperature of 25 degrees Celsius is 298 Kelvin (25 + 273 = 298).
A sample of nitrogen occupies 10 liters at 25oC and 98 7 kPa What would be the volume at 20oC and 102 7 kPa?
To solve this problem, we can use the combined gas law formula: P1V1/T1 = P2V2/T2 By substituting the values: (98.7 kPa)(10 L)/(298 K) = (102.7 kPa)(V2)/(293 K) Rearranging the equation gives: V2 = (98.7 kPa * 10 L * 293 K) / (102.7 kPa * 298 K) ≈ 9.75 L Therefore, the volume at 20°C and 102.7 kPa would be approximately 9.75 liters.
On which of the temperature scales does water boil at the highest numerical value?
Water boils at the highest numerical value on the Kelvin scale, at 373.15 K.
What state is oxygen at 298 K?
Oxygen is a gas at 298 K.
Is pOH found in acid?
Yes, there is a pOH value in acidic solutions which is above 7.0 at the temperature of 298 K.
What is 298 Fahrenheit converted into kelvins?
298 degrees Fahrenheit = 420.93 K.
Which pH number is considered acidic?
At the temperature of 298 K, any pH value lesser than 7.0 is considered to be acidic.
What is the general from of equation of all vertical lines?
It is: x = k whereas k is a numerical value on the x axis and is a line parallel to the y axis through (k, 0)
How do you firgure Kw from watts?
That ' K ' means ' 1,000 '. Divide 'watts' by 1,000 to get 'Kw' .
When do multiples of A and 9 meet?
To answer that, you'll need to have a numerical value for the letters.
Why do you use k after a numerical value?
It means thousand. So if someone said their salary is 200k then they mean 200 thousand.
What is the velocity of hydrogen at 298 K?
The average velocity of hydrogen molecules at 298 K can be calculated using the root mean square velocity formula, v = √(3kT/m), where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the mass of a hydrogen molecule. The average velocity of hydrogen at 298 K would be around 1926 m/s.
