<span>A fast way to separate the mixture would be to use a magnet. Iron is magnetic while copper is not. The second method would be to visually separate them since iron and copper distinctly different colors.</span>
Answer:
Answers are bellow.
Explanation:
The element with electron configuration 1s22s22p63s1 belong I A group in the periodic table and it is sodium because it loses one electron.
We have periodic table in attachments.
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell, which it readily donates, creating a positively charged ion—the Na+ cation. Its only stable isotope is 23Na.
The free metal does not occur in nature, and must be prepared from compounds.
It is soft metal, reactive and with a low melting point.
The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down.
Take note of the subscript written for each element in the compound. To find the total number of moles, make sure to multiply the subscript with the number of moles of compound. The answer for each is written below:
a. 3*1 = 3 moles Nitrogen; 3*3 = 9 moles Hydrogen
b. 0.25*2 = 0.5 moles Hydrogen; 0.25*1 = 0.25 moles Oxygen
c. 5*2 = 10 moles Hydrogen; 5*1 =5 moles Sulfur; 5*4 = 20 moles Oxygen
d. 0.75*1 = 0.75 moles Calcium; 0.75*1*2 = 1.5 moles Nitrogen; 0.75*3*2 = 4.5 moles Oxygen
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.
