Answer:
4O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 3H₂O (g)
4 would be the smallest possible integer for O₂
Explanation:
The balanced equation is this one:
8O₂ (g) + C₅H₁₂ (g) → 5CO₂ (g) + 6H₂O (g)
If we divide stoichiometry /2 (the half) we can consider that we use, the smallest possible integers.
8/2O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 6/2H₂O (g)
4O₂ (g) + 1/2C₅H₁₂ (g) → 5/2CO₂ (g) + 3H₂O (g)
Answer;
D. carbon-12 atom
Explanation;
-One atomic mass unit is the mass that is exactly equal to one-twelfth the mass of one carbon-12 atom. Therefore, the mass of carbon-12 is 12 amu and this provides the standard that is used in measuring the atomic mass of all other elements.
-The atomic mass of carbon is 12.01 and not 12.00 in the periodic table.
-Due to the fact that there are more than one element for most naturally occurring elements, the average mass of the naturally occurring mixture of isotopes is taken while determining the atomic mass of an element.
Answer:
activation energy hope this is right
Ans: 50m per sec
Explanation:
Speed= distance / time
therefore speed = 100m/2sec
=50m per sec
