The balanced equation for the above reaction is as follows;
2Ca + O₂ ---> 2CaO
stoichiometry of Ca to O₂ is 2:1
we first need to find the limiting reactant
number of Ca moles - 6.84 mol
number of O₂ moles - 4.00 mol
if Ca is the limiting reactant
if 2 mol of Ca reacts with 1 mol of O₂
then 6.84 mol of Ca reacts with - 6.84 / 2 = 3.42 mol of O₂
this means that Ca is the limiting reactant and O₂ is in excess
therefore amount of CaO produced depends on amount of limiting reactant present
stoichiometry of Ca to CaO is 2:2
number of moles of Ca reacted = number of CaO moles formed
number of moles of CaO formed - 6.84 mol
answer is 6.84 mol
Which of the following processes moves rock materials across the surface of the earth?
C. Erosion
Good luck! :)
(20*1000)÷(molecular weight of H3po4*50)
Explanation:
As it is given that W = = 28.9 lbf
Mass is given as 30.0 lbm
Now, calculate as follows.
=
= 0.9633 lbf/lbm
Since, it is known that 1 lbf = lbm \times . Therefore, local gravity (g') will be calculated as follows.
=
Thus, we can conclude that the value of local gravity is .
