Answer:
S–34
Explanation:
From the question given above, the following data were obtained:
Neutron number = 18
The isotope of sulphur still retains its atomic number of 16.
Recall:
Atomic number = proton number
Atomic number of sulphur (S) = 16
Therefore,
Proton number = 16
Next, we shall determine the mass number of the sulphur isotope. This can be obtained as follow:
Proton number = 16
Neutron number = 18
Mass number =.?
Mass number = Proton + Neutron
Mass number = 16 + 18
Mass number = 34
The symbol for sulphur is S.
Thus, the symbol of sulfur isotope that contains 18 neutrons is S–34
Answer:Plant material, lignite, sub-bituminous, bituminous, and anthracite
Explanation: Decomposing plant material over time and under pressure forma lignite which is a very dirty type of coal. As time and pressure increase, more energy is released and the trend points that there are less pollutants when it is burned!
Answer:
nuclear energy and solar geothermal
Explanation:
nuclear energy generates heat to produce steam, which is used by a turbine generator to generate electricity
solar geothermal heat pump system allows homeowners to tap into the energy sent down from the sun that is stored by the earth
