There are a total of four quantum numbers that govern the
electrons. These are the principal quantum number (n), the angular quantum
number (l), the magnetic quantum number (ml) and lastly the spin quantum number
(ms). Each electron has a unit set of the four quantum numbers.
Since the first 3 quantum numbers is already specified, so
the remaining to be filled is the ms quantum number which can only have values
of +1/2 and -1/2. So we have 2 electrons.
Answer:
<span>2 electrons</span>
According to the chemical equation, the reaction ratio between O2 and CO2 is 2:1, which mean for every 2 moles of O2 reacted there is 1 mole of CO2 formed.
Use the molar mass and mass of O2 to find out the moles of O2: moles of O2 = mass of O2/molar mass of O2 = 8.94g/32.00g/mol = 0.2794 mole. Therefore, the moles of CO2 that formed is 0.2794moles/2 = 0.1397 mole
Use the moles and molar mass CO2 to find out the mass of CO2:
Mass of CO2 = moles of CO2 * molar mass of CO2 = 0.1397 mole * .44.01g/mole = 6.15 g.
So the answer is B 6.15g.

Can you please make the question more precise..
Thanks..
The main cause of increased erosion is natural elements like rain, wind and ice. Erosion is the process by which the surface of the Earth gets worn down.
Soil erosion is also a big thing, it is caused by mostly rain that contributes to floods. This stuff is bad for farmers because they do a lot of farming and with erosion increasing the growing crops are decreasing because of erosion.
