C. It has mass and volume
Explanation:
Every atom of an element has mass and volume. Mass is the amount of substance it contains this is usually a function of their subatomic particles.
The bulk of the mass of an atom is concentrated in the nucleus where we have protons and neutrons. Electrons do not really add much to the mass of an atom.
Atoms also have specific volume.
- The reason for our selection is that atoms are the smallest particle of matter.
- Matter is anything that has weight and occupies space.
- Since it is matter, it must have specific weight and volume

<span>The Mechanical energy in a mechanical system is determined by adding the potential and kinetic energy together. </span>
Momentum = mass x velocity 750x25 = 18750 kg-m/s.
Answer:
B?
Explanation:
In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles. Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
Answer:
D
Explanation: Decreasing the temperature of the system would lower the reaction rate.
