Answer:
0.138 moles of oxygen are needed to combine with 0.276 moles of carbon.
Explanation:
Given data:
Moles of oxygen needed = ?
Moles of carbon present = 0.276 mol
Solution:
Chemical equation:
2C + O₂ → 2CO
Now we will compare the moles of carbon with oxygen.
C : O₂
2 : 1
0.276 : 1/2×0.276 = 0.138 mol
Thus, 0.138 moles of oxygen are needed to combine with 0.276 moles of carbon.
In polymer chemistry, polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize them.
Answer:
Well this is a metathesis or partner exchange reaction....and barium sulfate is as soluble as a brick...
Explanation:
And so...
Ba(NO3)2(aq)+K2SO4(aq)→2KNO3(aq)+BaSO4(s)⏐↓
Note that you simply HAVE TO KNOW that barium sulfate is insoluble....as is lead sulfate, and as is (less so) calcium sulfate
