<span>Dry ice is frozen carbon dioxide. It is easy to assume that the fog surrounds dry ice is carbon dioxide returning to it's gaseous however, you can not see that process. The vapors you see is the water molecules in the air condensing as a result of the cooling or energy removal by the dry ice. When energy is removed from water molecules they become colder and move slower than water in a gaseous. Similar to clouds in the air, the water condenses into a form that you can see.</span>
Answer:
Check Explanation.
Explanation:
When we are talking about the reservoirs of carbon we mean the places where carbon are been stored. So, we will be considering the places where carbon can be stored in our planet. Remember that carbon is the 6th element in the periodic table or chart.
Within these Reservoirs, the carbon moves from one to another and that is called Carbon cycle. The reservoirs of carbon can be in the atmosphere, the lithosphere and in the biosphere.
(1). Carbon can be stored in the atmosphere as Carbondioxide,CO2.
(2). Carbon can be found on lithosphere in sedimentary rock such as limestone. Also, as components in fossil fuels.
(3). Carbon can be found in the biosphere as soil carbon.
Answer:
The pressure of CO2 = 0.48 atm
Explanation:
Step 1: Data given
Kp = 0.23
Step 2: The balanced equation
2NaHCO3(s) ↔ Na2CO3(s) + CO2(g) + H2O(g)
Step 3: Calculate the pressure of CO2
Kp = (p(CO2))*(p(H2O))
For 1 mol CO2 we have 1 mol H2O
x = p(CO2) = p(H2O)
Kp = 0.23 = x*x
x = √0.23
x = 0.48
pCO2 = x atm = 0.48 atm
The pressure of CO2 = 0.48 atm
Explanation:
so, as you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. electronegativity increases as you move from left to right across a period on the periodic table.
