Answer:
The answer to your question is 3 moles of Fe and 4.5 moles of S
Explanation:
Data
moles of Fe = ?
moles of S = ?
moles of Fe₂S₃
Unbalanced chemical reaction
Fe + S ⇒ Fe₂S₃
Reactants Elements Products
1 Fe 2
1 S 3
Balanced chemical reaction
2Fe + 3S ⇒ Fe₂S₃
Reactants Elements Products
2 Fe 2
3 S 3
-Calculate the moles of each reactant
2 moles of Fe ------------------- 1 mol of Fe₂S₃
x -------------------- 1.5 moles Fe₂S₃
x = (1.5 x 2) / 1
x = 3 moles of Fe
-Calculate the moles of S
3 moles of S --------------------- 1 mol of Fe₂S₃
x --------------------- 1.5 moles of Fe₂S₃
x = (1.5 x 3) / 1
x = 4.5 moles of S
Answer:
FLUORINE
Explanation:
It has 5 electrons In Its 2P shell!
11.0 kg = (11.0 kg)(1000 g/kg) = 11000 g
(11000 g)/(1400 cm3) = 7.857 g/cm3
Simplified = 7.86 g/cm3
Answer:
draw the carbon chain is containing 6 carbon then attach the aldehyde group with edge carbon in chain then put the put double bond at 3 no. carbon
Most definitely! Consider bacteria in a petri dish. Organisms need nutrition to survive, and when overcrowding is an issue (which by definition means that there is an insufficient amount of space/resources for the current population), organisms cannot survive and reproduce.
