Answer:
Density of aluminum is 2.699 g/cm^3
Explanation:
Density of a given material can be defined as the mass of the substance present in a unit volume. Mathematically it can be expressed as:
Units: g/cm^3 or kg/m^3
Aluminum (Al) is one the lightest element and is known to have a density of 2.699 g/cm^3
The field of energy is wide and interesting due to it can be expressed by differents way.
The thermal energy is associated like internal energy of the atoms or molecules of a substance. The transfer of thermal energy as heat can take place via convection.
Convection via is the transfer of thermal energy due to the motion of the substance that contains the thermal energy.
Answer:
C.) 2-butyne
Explanation:
Since the molecule has 4 central carbons, it has the prefix but-.
Since the molecule has a triple bond between central carbons, it has an ending of -yne.
Since the triple bond starts on the second carbon, it has a 2 - prefix.
Silicon, it's bring brother would be the prime candidate, although its compounds are notably different from those of carbon.
Answer:
Carbon or the symbol C has a mass percentage of 42.880% while Oxygen or symbol O has a mass percentage of 57.120%
