Answer:
candle.
Explanation:
Candle has more than one change chemical and physical.
Answer:
Explanation:
Molar heat capacity at constant volume Cv of a gas = n x .5 R where n is degree of freedom of the gas molecules
CO₂ is a linear molecule , so number of degree of freedom = 3 + 2 = 5
3 is translational and 2 is rotational degree of freedom . There is no vibrational degree of freedom given .
So Cv = 5 / 2 R
= 2.5 R .
All particles (atoms and molecules) of matter have kinetic energy because they are always in motion.
A measure of the kinetic energy of particle motion within a substance is temperature. If the particles move faster, they have more kinetic energy, and the substance has a higher temperature
O is what should go in the blank. O stands for Oxygen.
Answer:
The pH of the solution is 7, 52
Explanation:
The pH gives us an idea of the acidity or alkalinity of a solution. Is calculated:
pH = -log (H +)
pH= -log ( 3x10-8)= <em>7, 52</em>
