M(O₂)=20g
M(O₂)=32.0 g/mol
n(O₂)=20/32.0=0.625 mol
m(C)=12 g
M(C)=12.0 g/mol
n(C)=12/12.0=1.0 mol
2C + O₂ → 2CO
1 mol 0.625 mol 1 mol
0.625-0.5=0.125 mol
2CO + O₂ → 2CO₂
0.250 mol 0.125 mol 0.250 mol
n(CO)=1 mol - 0.250 mol = 0.750 mol
M(CO)=28.0 g/mol
m(CO)=0.750*28.0=21.0 g
n(CO₂)=0.250 mol
M(CO₂)=44.0 g/mol
m(CO₂)=0.250*44.0=11.0 g

PLEASE GIVE ME BRAINLIEST!
Answer:
Explanation:
Scientists don't stop with the first step of their experiment because they want other scientists' opinions because they may not trust their own observations.
OR
Scientists don't stop with the first step of their experiment because they would rather plan and run experiments than just observe the world around them
Hope any one of these helps you
Hydrogen bonds
Guanine-cytosine and adenine-thymine <em>hydrogen bonds</em> hold the strands of a DNA helix together.
Answer:
Explanation:
Hello, in this case, the lead is catching heat and the water losing it, that's why the heat relation ship is (D is for Δ):

Now, by stating the heat capacity definition:

Solving for the equilibrium temperature:

Which is very close to the water's temperature since the lead's both mass and head capacity are lower than those for water.
Best regards.
