The Fe is our limiting reactant here. First, convert the mass of Fe given to moles of Fe by dividing mass by the molar mass:
(51.3 g Fe)/(55.845 g/mol) = 0.9186 mol Fe.
According to the balanced equation, 2 moles of Fe2O3 are produced for every 4 moles of Fe that are consumed. In other words, half as many moles of Fe2O3 will be produced as there are Fe that react:
(0.9186 mol Fe)(2 mol Fe2O3/4 mol Fe) = 0.4593 mol Fe2O3.
Finally, convert the moles of Fe2O3 back to grams by multiplying by the molar mass of Fe2O3:
(0.4593 mol Fe2O3)(159.6882 g/mol) = 73.3 g Fe2O3.
So, 73.3 grams of Fe2O3 are formed.
What method can be used to separate benzoic acid and potassium carbonate
Answer:
To separate the components, a water wash may be attempted to remove benzoic acid, but benzoic acid is not particularly water-soluble due to its nonpolar aromatic ring, and only small amounts would be extracted into the aqueous layer
The method that can be used to separate Benzoic acid and potassium carbonate is : The application of water wash separation method
Benzoic acid is slightly soluble in cold water but becomes more soluble as the temperature of water is increased. Water wash separation method is a methodology used for the selective removal of unwanted compounds in a mixture.
Separation method based on solubility water wash methodprecipitationThe separation of benzoic acid and potassium carbonate is based on the solubility differences between Benzoic acid and potassium carbonate when dissolved in a solvent ( water ) therefore the water wash separation method is the most effective method.
Hence we can conclude that The method that can be used to separate Benzoic acid and potassium carbonate is : The application of water wash separation method.

a 5 g ice cube starts life at -1 C if 2182.5 j are added to it what will be the final temperature upon his demise ?
Answer:
Final Temp = 23.92°C
Explanation:
ΔH(total) = (m·c·ΔT)ice + (m·ΔH(f))melt'g + (m·c·ΔT)water
2182.5j = (5g)(2.092j/g·°C)(1°C) + (5g)(334.56j/g) + (5g)(4.184j/g·°C)(ΔT)
(2182.5 - 10.46 - 1672.8)j = 20.92j/°C·ΔT
ΔT = (2182.5 - 10.46 - 1672.8)j / 20.92j/°C = 23.92°C
Since the melting ice starts and ends at 0°C and is then warmed to 23.92°C then the temperature change is also the final temp of the water based upon given energy input values.

mmHg?
Round answer to 0.01 decimals
Answer:
.11 mol
Explanation:
Convert mmHg to atms by dividing by 760. Then multiply 6.3 by the atms and divide by .08206*(273+28) to get mol
A reaction in the laboratory yields 5.98 g KAI(SO2)2, How many moles of potassium aluminum
sulfate were produced?
Answer:
0.0308 mol
Explanation:
In order to convert from grams of any given substance to moles, we need to use its molar mass:
Molar mass of KAI(SO₂)₂ = MM of K + MM of Al + (MM of S + 2*MM of O)*2Molar mass of KAI(SO₂)₂ = 194 g/molNow we calculate the number of moles of KAI(SO₂)₂ contained in 5.98 g:
5.98 g ÷ 194 g/mol = 0.0308 molPlease help me with this question!!
Answer: 824.6 g of NaCl are produced from 500.0 g of chlorine.
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex] [tex]\text{Moles of} Cl_2=\frac{500.00g}{71g/mol}=7.04moles[/tex]
[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]
According to stoichiometry :
1 mole of [tex]Cl_2[/tex] produce = 2 moles of [tex]NaCl[/tex]
Thus 7.04 moles of [tex]Cl_2[/tex] will produce=[tex]\frac{2}{1}\times 7.04=14.08moles[/tex] of [tex]NaCl[/tex]
Mass of [tex]NaCl=moles\times {\text {Molar mass}}=14.08moles\times 58.5g/mol=824.26g[/tex]
Thus 824.6 g of NaCl are produced from 500.0 g of chlorine.
