Through ratio and proportion, for every mole of O2, there is also a mole equivalent of CO2. In this case, we divide first 8.94 g O2 by 32 g/mol to convert the mass to mole. That is equivalent to 0.279375 mol which is also the amount of CO2. Multiplied by 44g/mol which is the molar mass of CO2, the answer is 12.29 grams CO2.
The answer would be condensation. In the other answer choices you're giving an action that would change the temperature. (eg. Melting, Heating, Cooling).
The answer is D
Because the bread cannot go back to its previous state, and because a new substance was formed. :)
Answer:
if you have 8 moles of O2 how many moles of H2O can be producedhhdg
CH4+O2 = CO2+2H2O
C-1 C-1
O-2 O-4
H-4 H-4
CH4+<u><em>2 </em></u>O2 = CO2+2 H2O
C-1 C-1
O-2-4 O-4
H-4 H-4
You add a 2 in front of the O2 on the reactant side so the Oxygen can balance on the Product side
