The average kinetic energy of translation of oxygen molecules in the gas is 5.05 × 10⁻²¹
The given data is
n = 2
v = 20
P = 92
K.E = 3 / 2 KbT
= 3 / 2 PV / N
= 3 / 2 Pv / nNa
K.E = 3 / 2 × 9 × 1.013 × 10⁵ × 20 × 10⁻³ / 2 × 6.022 × 10²³
K. E = 5.05 × 10⁻²¹ J
<h3>Average kinetic energy</h3>
The average kinetic energy (K) is equal to one half of the mass of each gas molecule times the RMS speed squared
Hence, the average kinetic energy is 5.05 × 10⁻²¹ J

Answer:
B. 0.7%
Explanation:
Given data:
Actual boiling point = 82.5°C
Experimental boiling point = 83.1°C
Percent error = ?
Solution:
Formula:
Percent error = ( actual value - experimental value / actual value )×100
by putting values,
Percent error = (82.5°C - 83.1 °C /82.5°C) × 100
Percent error = 0.007 × 100
Percent error = 0.7 %
Negative sign shows that experimental value is greater than accepted value. It can not written in result.
Strong acid does not conduct electricity. Question 4} A. H30 Question 5 } B. NaOH + CH3COOH
Mass is the amount of matter in an object, and weight is the downward pull on an object due to gravity. Which property of physical changes explains why matter is conserved in a physical change? The bonds between atoms do not break; it is only the arrangement that changes.
hope I helped! :)
Answer:The Peruvian west coast bordering the Pacific Ocean is a long desert strip that stretches from the departments of Tumbes in the north bordering Ecuador, to Tacna in the south bordering Chile for a total length of 1,555 miles or 2,500 km. The average temperature from December to April is 25 to 28C or 53 to 59F and the average temperature from May to November is 12 to 15C or 53 to 59F.
The coast covers about 10% of the territory but is home to more than 50% of the population. Large cities such as Lima, the capital, Trujillo, Chiclayo and Tacna are located in the coast. Cities along the coast are the center of economic activity attracting people from the interior of the country looking for economic prosperity.
idk hope this helps !!!!
