Answer:
<em>The correct option is C) The number of collisions of gas particles decreases</em>
Explanation:
The molecules in a gas are not located close to each other as molecules in a solid or a liquid. The molecules in a gas have more energy. If we decrease the number of particles in a gas, then there will be reduced collisions as the molecules are already located further apart.
However, a decrease in the volume will affect the pressure of a gas, not the decrease in the number of gas particles.
Energy will always be transferred from the hottest to the coolest object until their temperatures are equal.
Answer:
The empirical formula of ribose (a sugar) is CH2O. In a separate experiment, using a mass spectrometer, the molar mass of ribose was determined to be 150 g/mol.Explanation:
