Answer: c12 has a mass of 12 amu
Explanation:
mass of one mole of c12 = g. So mass of 1 atom of c12 = 1.9927e-23g
Answer: A. O2
Explanation:
If photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), subsequent analysis will show that 18O first appears then 3-phosphoglycerate molecule produced by the algae.
Explanation:
The temperature of the molten iron remained constant at 2750°C because of the heat absorbed to effect the phase change and not to change the temperature.
The heat of vaporization is a latent or hidden heat absorbed by substances that causes a phase change from liquid to gas.
- In essence, the heat is used to break intermolecular bonds between the particles of the melted vat.
- If enough heat is no supplied the molten vat will not boil off and become vapor.
- In transitioning from liquid to gas, heat is absorbed by a body to effect the phase change.
- When the body acquires enough heat, the particles are able to break off and boil.
- At the 2750°C mark, this is what is happening.
