The atomic number or (also called) the proton number, represents the number of protons, which also represents the number of electrons in that single atom itself (an atom which has not gone through reactions of any kind will have the same number of electrons as number of protons).
Hope this helps! :)
P.s. This question seems more of a Chemistry than Biology question in my opinion
To solve for the mass of a substance is to simply get the
product of volume and density, that is:
mass = density * volume
So calculating for mass:
mass = (2.76 g / cm^3) * 6 cm^3
mass = 16.56 g

Answer:
Driving a car, smoking, burning of woods for heating purpose and cooking food.
Explanation:
Driving a car, smoking, burning of woods for heating purpose and cooking food are the activities that are performed in our home daily. These activities greatly affected the biogeochemical and hydrologic cycles by increasing the concentration of carbondioxide gas in the atmosphere. Burning of fossil fuels in the car engine and burning of woods releases carbondioxide gas that causes air pollution. The use of electric cars and electric heater can decrease the impact on these biogeochemical and hydrologic cycles.
