Answer:
50.0 °C
Explanation:
If all other variables are being held constant, you can find the temperature using Guy-Lussac's Law. The equation looks like this:
P₁ / T₁ = P₂ / T₂
In this equation, "P₁" and "T₁" represent the initial pressure and temperature. "P₂" and "T₂" represent the final pressure and temperature. You can find the missing temperature (T₂) by plugging the given values into the equation and simplifying.
P₁ = 405 pKa P₂ = 1013 pKa
T₁ = 20 °C T₂ = ? °C
P₁ / T₁ = P₂ / T₂ <----- Guy-Lussac's Law
405 pKa / 20 °C = 1013 pKa / T₂ <----- Insert values
20.25 = 1013 pKa / T₂ <----- Divide 20 from 405
20.25 x T₂ = 1013 pKa <----- Multiply both sides by T₂
T₂ = 50.0 °C <----- Divide both sides by 20.25
Alpha particle is nucleus of a helium-4 atom, which is made of two protons and two neutrons.
Nuclear reaction: ²²²Rn → ²¹⁸Po + α (alpha particle).
Alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.
Hey there!
We use the Clapeyron equation :
P * V = n * R * T
2.45 * V = 0.500 * 0.0821 * 303
2.45 * V = 12.43815
V = 12.43815 / 2.45
V = 5.07 L
hope this helps !
The answer is work i believe
False. Because gas to a liquid is called condensation
