Answer:
lAs can be seen from the chemical equation, each mole of
F
e
2
C
O
3
needs 3 moles of
C
O
. If 30 moles of
C
O
are used, only 10 moles of
F
e
2
C
O
3
can be reduced, generating 20 moles of
F
e
, corresponding to 1117 grams of iron.
Answer:
220g of CO2
Explanation:
Step 1:
The balanced equation for the reaction.
2C5H11OH + 15O2 —> 10CO2 + 12H2O
Step 2:
Determination of the number of mole of CO2 produced by burning 1 mole of C5H11OH.
From the balanced equation above,
2 moles of C5H11OH produced 10 moles CO2.
Therefore, 1 mole of C5H11OH will produce = (1 x 10)/2 = 5 moles of CO2.
Therefore, 5 moles of CO2 is produced from the reaction.
Step 3:
Conversion of 5 moles of CO2 to grams.
Molar mass of CO2 = 12 + (2x16) = 44g/mol
Number of mole of CO2 = 5 moles
Mass of CO2 =...?
Mass = mole x molar mass
Mass of CO2 = 5 x 44
Mass of CO2 = 220g.
Therefore, 220g of CO2 were obtained from the reaction.
Answer:
What happens when an acid is mixed with water?
Explanation:
When you mix acid with water, it's extremely important to add the acid to the water rather than the other way around. This is because acid and water react in a vigorous exothermic reaction, releasing heat, sometimes boiling the liquid. When you add water to acid, the water boils and the acid may splatter and splash.
Answer:
Exothermic interractive are the following: NaOH, KOH, CaCl₂
Endothermic interactive are the following: NaCl, NH₄NO₃, NaNO₃
Explanation:
Answer:
i think this is what you mean: nuclear energy produces too much waste, which will cause more problems, even if the electricity solves the problem of global warming
Explanation:
sorry if this isn't correct, i don't rly understand the way you phrased the question.
