Explanation:
1. carbon cycle
all of the physical processes and chemical reactions that result in the movement of carbon between the biosphere (living forms) and the geosphere (water, earth, and atmosphere)
Carbon cycle is the cyclic movement of carbon in various form on earth. This process entails both physical and chemical processes that ensures that carbon moves in different spheres of the earth. Carbon is one of the most important element in life. It is the building block of most organic processes on earth.
2. carbon footprint
a calculation that considers an individual's contribution to the process of global warming based on activities leading to greenhouse gas production
Carbon footprint is important in mapping the quota of carbon emitted into the atmosphere
It is the amount of greenhouse gases contributed into the atmosphere by individuals.
3. global warming
an overall increase in world temperatures that may be caused by additional heat being trapped by greenhouse gases
It is the overall increase in global temperature. It has severe consequences.
Global warming results when greenhouse gases in the atmosphere traps outgoing radiation in an anomalous way.
4. greenhouse gas
components of the air mixture that trap infrared (heat) energy
Greenhouse gases are gases that prevents long wave radiation from leaving the earth surface. They absorb the gases in turn, warming occurs on earth.

63.1 g of NaN3 is formed when 50.0 g of sodium is reacted with 40.5 g of nitrogen according to the balanced chemical reaction
The balanced reaction equation is;
2 Na + 3 N2--> 2 NaN3
Number of moles of Na = 50.0 g/23 g/mol = 2.17 moles of Na
Number of moles of Nitrogen = 40.5 g/28 g/mol = 1.45 moles of N2
We have to obtain the limiting reactant, this is the reactant that yields the least number of moles of product.
For Na
2 moles of Na yields 2 moles of NaN3
2.17 moles of Na yields 2.17 moles of NaN3 (reaction is 1:1).
For N2
3 moles of N2 yields 2 moles of NaN3
1.45 moles of N2 yields 1.45 * 2/3 = 0.97 moles of NaN3
So, N2 is the limiting reactant. Mass of product formed depends on the limiting reactant.
Mass of NaN3 = 0.97 moles of NaN3 * 65 g/mol = 63.1 g of NaN3
Therefore, 63.1 g of NaN3 is formed when 50.0 g of sodium is reacted with 40.5 g of nitrogen according to the balanced chemical reaction

It’s a Chemical Reaction so If one of the reactants is a solid, the surface area of the solid will affect how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid solid interface, i.e. on the surface of the solid. So the larger the surface area of the solid, the faster the reaction will be.
