Matter is never destroyed, nor created. So, this is false.
Given:
Mass, m = 51.1 g
Volume, V = 6.63 cm³
By definition,
Density = Mass/Volume
= (51.1 g)/(6.63 cm³)
= 7.7074 g/cm³
In SI units,
Density = (7.7074 g/cm³)*(10⁻³ kg/g)*(10² cm/m)³
= 7707.4 kg/m³
Answer: 7.707 g/cm³ or 7707.4 kg/m³
Answer:
Potential Energy:
- Hot water
- Ball at the top of a hill
- Battery
- Food
Kinetic Energy:
- Wave in the ocean
- Ball rolling down a hill
- Spinning motor
- Person running
Explanation:
Potential energy is the energy that is capable of generating work as a consequence of the position of a body.
The kinetic energy of a body is that energy that it possesses due to its movement.
(29.8 g) / [0.184 mol (44.00964 g CO2/mol)] =0.832= 83.2% yield CO2
(hope this helps)
