We use the famous equation:
E = mc2
Where E is energy, m is the mass of the object and c is the speed of light.
We plug in our values:
E = (1 x 10-3 kg) (3 x 108)2
E = 9 x 1013 J
If 1.0g of matter were converted to energy, how much energy would be formed?

the density of most solids is greater than 1.0g/cm^3. the density of carbon dioxide gas is much smaller than that (0.002g/cm^3). How does our particle model of matter account for the difference? perticle diagram needed.
2. If the ammonia solution of Na were not completely converted to NaNH2, how would this affect the subsequent preparation of [Cr(NH3)6](NO3)3? 3. If a large excess of Fe(NO3)39H2O were added to the NH3 solution of Na, how would this affect the yield of [Cr(NH3)6](NO3)3 and why?
How much energy is required to accelerate a spaceship with a rest mass of 139 metric tons to a speed of 0.528 c? Hints: In the acceleration process the energy we have is converted to the kinetic energy of the spaceship. The classical kinetic energy of an object is half of the mass multiplied by the square of the velocity. What is the relativistic form of the kinetic energy? Incorrect.
