I think its 2-, it gained 2 electrons.
Propanol molecular formula is C₃H₇OH
the balanced reaction for combustion of propanol is as follows;
2C₃H₇OH + 9O₂ --> 6CO₂ + 8H₂O
Molar ratio of reactants to products can be found out by the stoichiometry.
By looking at the coefficients of reactants and products in the balanced reaction equation, molar ratio can determined.
Therefore the molar ratio of propanol to CO₂ is 2:6, simplified --> 1:3
Answer:
emissions by factories is the answer
Explanation:
Factories produce air pollution which is polluted air, the other options
decay of organisms, photosynthesis (convert light energy into chemical energy - and returns CO2), and cellular respiration are all of the ways carbon dioxide returns to the atmosphere.
Hope this helped! Have a nice day, be safe and healthy :)
Answer:
The table is preventing the book from accelerating downwards.
Explanation:
Answer:
4)Particle Arrangement
Explanation:
When solid carbon dioxide CO₂ will evaporate in gaseous carbon dioxide CO₂ the particles arrangement will change from ordered in solid state to completely disordered in gaseous state.
Bond type, gram formula mass and molecular polarity are not changed in the described physical transformation.
